Dual in-line package

The Dual in-line package (DIP), also referred to as the dual inline package, is a type of integrated circuit (IC) packaging format characterized by a rectangular body—typically made of molded plastic, ceramic, or epoxy—with two parallel rows of electrical connecting pins extending from the longer sides.^[1] These pins, usually numbering from 4 to 68 or more, are arranged on a standard 2.54 mm (0.1 inch) pitch and designed for through-hole insertion into printed circuit boards (PCBs), where they are soldered in place for mechanical and electrical connection.^[1] Originating from Fairchild Semiconductor in 1964, the DIP revolutionized semiconductor assembly by enabling higher pin counts than prior formats like the TO-5 metal can, facilitating the mass production of complex ICs and becoming the industry standard through the 1970s and 1980s.^[1]^[2] The DIP's development addressed the growing complexity of ICs, which demanded more input/output connections beyond the roughly 10 pins supported by early packages.^[2] Invented by Fairchild engineers Don Forbes, Rex Rice, and Bryant Rogers, the initial 14-lead ceramic version featured pins spaced 100 mils (2.54 mm) apart, allowing direct socket insertion or PCB soldering while supporting automated handling and testing.^[2]^[3] This innovation marked a pivotal shift toward system-level design considerations in packaging, as it prioritized compatibility with PCB layouts and machine assembly over die protection alone.^[3] Key advantages of the DIP include its low cost, mechanical robustness, ease of prototyping, and compatibility with wave soldering processes, making it ideal for low- to medium-pin-count applications in consumer electronics, microcomputers, and embedded systems.^[1] However, limitations such as larger footprint, higher profile, and challenges with high I/O densities led to its gradual replacement by surface-mount technologies like small-outline integrated circuits (SOICs) and ball grid arrays (BGAs) starting in the late 1980s.^[1]^[2] Despite this, DIPs persist in niche uses, including hobbyist projects, educational tools, and legacy repairs, with modern variants occasionally incorporating enhanced thermal or electrical performance.^[1]

Overview

Definition and Characteristics

The dual in-line package (DIP), also known as dual in-line integrated circuit (DIL IC), is an electronic component enclosure featuring a rectangular housing with two parallel rows of pins extending from the base on opposite sides.^[4] This configuration allows for straightforward insertion into sockets or printed circuit boards (PCBs), making it a staple for housing integrated circuits (ICs) and discrete semiconductor devices.^[5] Key characteristics of the DIP include its through-hole mounting design, where the pins pass through holes in the PCB and are soldered on the opposite side for secure attachment.^[6] The standard pin spacing, or pitch, measures 0.1 inches (2.54 mm) between adjacent pins in each row, facilitating compatibility with common PCB grids.^[7] Body width, defined by the row spacing between the two parallel pin sets, is typically 0.3 inches (7.62 mm) for standard DIPs accommodating up to 40 pins, though narrower variants exist at 0.15 inches (3.81 mm) or 0.2 inches (5.08 mm) for space-constrained applications.^[7] The package height generally ranges from 0.13 to 0.2 inches (3.3 to 5.08 mm), with pins extending outward and often pre-bent at a 90-degree angle for perpendicular insertion into the board. The primary purpose of the DIP is to offer robust mechanical support, reliable electrical interconnections via the pins, and protection against environmental factors such as moisture, dust, and mechanical stress for enclosed ICs or components.^[8] Package length varies with pin count to accommodate the internal die and bonding; for instance, an 8-pin DIP typically measures about 0.4 inches (10.16 mm) in body length, while higher-pin-count versions like 16-pin extend to approximately 0.75 inches (19 mm).^[9] These dimensions adhere to JEDEC standards, ensuring interoperability across manufacturers.^[7]

Historical Development

The dual in-line package (DIP) was invented in 1964 by engineers Don Forbes, Rex Rice, and Bryant Rogers at Fairchild Semiconductor to address the need for a more reliable and manufacturable housing for integrated circuits (ICs) with expanding pin counts, replacing fragile earlier designs like flat-packs.^[10]^[3] This innovation emerged amid rapid advancements in IC technology, enabling better protection against handling damage and improved compatibility with assembly processes.^[2] During the 1960s and 1970s, the DIP saw widespread early adoption, particularly for transistor-transistor logic (TTL) chips such as the 7400 series and pioneering microprocessors including the Intel 4004 introduced in 1971.^[11]^[12] Its straightforward pin arrangement and robust construction facilitated automated insertion into circuit boards, contributing to its status as a de facto industry standard by the mid-1970s for logic and computing applications.^[2] The Joint Electron Device Engineering Council (JEDEC) formalized these designs in the late 1960s through standards like MS-001, which defined dimensions for plastic DIPs accommodating 8 to 40 pins with a 0.300-inch row spacing.^[7] The DIP achieved peak popularity in the 1980s, powering consumer electronics from personal computers to televisions due to its low cost, ease of prototyping, and proven reliability in high-volume production.^[13] Its dominance began to wane in the 1990s as surface-mount technologies, such as the small-outline integrated circuit (SOIC), offered greater density and suitability for automated surface-mount assembly lines.^[14] In niche sectors, high-reliability variants of the DIP—often ceramic for enhanced hermetic sealing and radiation tolerance—persist for demanding environments, with specialized offerings for aerospace and defense applications that meet stringent military specifications like MIL-PRF-19500.^[15]

Construction

Materials and Body Types

The dual in-line package (DIP) primarily utilizes two main materials for its body construction: epoxy-based plastic for the plastic dual in-line package (PDIP) and ceramic for the ceramic dual in-line package (CERDIP). PDIPs employ an opaque molded epoxy resin, which encapsulates the internal components cost-effectively while providing basic mechanical protection.^[16] In contrast, CERDIPs use high-purity alumina ceramic, offering superior reliability in demanding environments such as military and aerospace applications due to its enhanced resistance to environmental stressors.^[17] The manufacturing process for DIPs begins with die attachment, where the semiconductor die is bonded to a metal lead frame using adhesive or solder, followed by wire bonding to establish electrical connections between the die and the lead frame. For PDIPs, encapsulation occurs via transfer molding, in which preheated epoxy resin pellets are injected under pressure into a mold cavity containing the assembled lead frame, forming a non-hermetic seal that solidifies to protect the die from handling damage. CERDIPs, however, involve a hermetic sealing process after wire bonding, typically using a metal lid brazed or welded onto the ceramic body with glass frit or solder, ensuring an airtight barrier against external contaminants.^[18]^[19] DIP body types include molded plastic for standard non-hermetic applications, ceramic packages with metal lids for hermetic protection, and open-cavity variants such as windowed CERDIPs, which feature a transparent quartz or glass lid for ultraviolet light access in erasable programmable read-only memory (EPROM) prototyping. These open-cavity designs facilitate reprogramming during development but require careful handling to maintain integrity.^[19] The choice of material significantly impacts performance: epoxy plastic in PDIPs provides economical production with adequate durability for consumer electronics but exhibits lower thermal conductivity (typically 0.5–1 W/m·K), limiting heat dissipation in high-power scenarios. Ceramic bodies in CERDIPs, with thermal conductivity around 20–30 W/m·K, excel in heat transfer and offer robust protection against moisture ingress and ionizing radiation, enhancing longevity in harsh conditions, though at higher cost.^[20]^[21]

Lead Design and Configuration

The lead frame in a dual in-line package (DIP) is constructed from a thin sheet of copper or copper alloy, which is stamped or etched to create a precise structure that supports the integrated circuit die and forms the electrical pathways to the external leads. This lead frame undergoes surface plating with tin, gold, or solderable alloys to improve wettability during soldering and protect against corrosion.^[22]^[23] Internally, the leads of the frame connect to the die via fine bond wires, typically made of gold or aluminum alloy with diameters around 25 μm, which are ultrasonically or thermosonically bonded from the die's contact pads to the inner lead fingers. These connections are then fully encapsulated within the package body to shield them from environmental factors and mechanical stress, ensuring reliable signal transmission.^[24] The external leads extend from the package body and are formed by bending the lead frame material at approximately 90 degrees, resulting in straight, parallel projections suitable for through-hole insertion into printed circuit boards; common configurations include straight leads for vertical mounting or slight gull-wing bends for surface-mount adaptations in some variants. These leads typically project 0.125 to 0.2 inches (3.2 to 5.1 mm) to accommodate PCB hole insertion and soldering.^[25]^[23] In terms of configuration, DIP leads are arranged in two parallel rows along the longer sides of the rectangular package body, with an even number of total pins—ranging from 8 to 64 in standard types—for symmetrical electrical and mechanical balance; the rows are spaced according to established standards such as those from JEDEC to facilitate consistent board mounting.^[1]^[26]

Variants

Standard DIP Types

The Plastic Dual In-line Package (PDIP) is the most common variant of the DIP, characterized by its molded plastic body and two parallel rows of leads spaced 0.3 inches (7.62 mm) apart, making it suitable for low-cost, general-purpose applications in consumer electronics and prototyping. Defined under JEDEC standard MS-001, the PDIP features a rectangular body typically 0.3 inches wide, with lead counts ranging from 8 to 40 pins, and is designed for through-hole mounting on printed circuit boards.^[27] Its non-hermetic construction prioritizes affordability and ease of manufacturing over extreme environmental resilience, with operating temperatures generally limited to -40°C to 85°C in standard grades.^[27] The Ceramic Dual In-line Package (CERDIP), also known as CDIP, employs a hermetically sealed pressed ceramic body for enhanced reliability in harsh environments, particularly military and aerospace applications where protection against moisture, contaminants, and mechanical stress is essential. Constructed from two dry-pressed alumina ceramic sections joined with glass frit, the CERDIP maintains the standard 0.3-inch lead row spacing but offers superior thermal conductivity and resistance to outgassing compared to plastic variants.^[28] It supports high-temperature operation up to 175°C or more in certain configurations, enabling use in high-reliability systems such as avionics and defense electronics.^[29] Footprint-compatible with PDIP, CERDIP packages are qualified under MIL-STD specifications for extended life cycles in radiation-prone settings.^[30] The Shrink Dual In-line Package (SDIP or SPDIP) is a compact evolution of the standard DIP, featuring the standard body width of 0.3 inches (7.62 mm) but with closer lead spacing (typically 0.07 inches or 1.78 mm) to enable higher pin counts and component density on circuit boards while retaining the dual-row lead configuration. Primarily molded in plastic like the PDIP, the SDIP reduces the pitch between pins for improved board real estate efficiency, making it ideal for space-constrained designs in telecommunications and computing hardware.^[31] Available in lead counts up to 64 pins, it supports similar general-purpose uses as PDIP but may require adjusted socket or soldering techniques due to the reduced dimensions.^[31] High-reliability DIP variants, including radiation-hardened types, adapt the ceramic-based CERDIP structure for space and defense missions, incorporating specialized materials and processes to withstand total ionizing dose levels exceeding 100 krad and single-event effects. These variants use enhanced alumina ceramics and lead frames tested for neutron and gamma radiation tolerance. They maintain compatibility with standard DIP footprints but prioritize hermetic sealing and burnout-resistant designs for mission-critical reliability.^[32] The Single In-line Package (SIP) features a rectangular body with leads arranged in a single row along one side, typically the longer edge, resulting in a narrower footprint compared to the dual-row configuration of standard DIPs.^[33] This design, standardized under JEDEC as an in-line package with leads on only one side, emerged in the 1960s and is commonly employed for passive components such as resistor networks, capacitors, and inductors, as well as low-capacity memory chips and simple operational amplifiers.^[26]^[34] By eliminating the second row of pins, SIP reduces the overall width required on printed circuit boards, facilitating denser layouts in applications like filters and small circuit modules while maintaining through-hole mounting compatibility.^[35] The Quad In-line Package (QIP), also referred to as QUIP in some standards, extends the in-line concept with four parallel rows of pins positioned along the edges of a rectangular housing, enabling higher pin counts than dual-row packages for legacy through-hole systems.^[36] Developed in the 1970s primarily for single-sided PCBs, this configuration supports up to 42 pins or more in examples like the QIP-42, accommodating complex connectivity in older electronics without expanding the package footprint excessively.^[37] The staggered rows improve solder pad spacing and reliability on boards with limited routing layers, though they introduce mounting challenges due to the increased pin density and alignment precision required.^[38] The Zig-zag In-line Package (ZIP) modifies the single-side lead arrangement by offsetting pins in a staggered, alternating pattern along one edge, achieving denser spacing than traditional SIP or DIP while preserving through-hole insertion.^[26] Evolving in the early 1980s as a DIP alternative for compact designs, ZIP was particularly applied to dynamic RAM chips, transistor arrays, resistor networks, amplifiers, and small integrated circuits, with lead pitches around 1.27 mm allowing up to 40% higher pin density in memory modules.^[39] This zig-zag formation enhances board space efficiency but demands careful handling to avoid lead deformation during assembly.^[40] These related packages differ from standard dual-row DIP variants by altering pin row count and arrangement to optimize for specific constraints: SIP minimizes width for narrow applications, QIP boosts pin capacity at the cost of mounting complexity, and ZIP provides denser single-side integration for evolving 1980s demands like higher-density memory.^[36]^[26]

Applications

Device Integration

The dual in-line package (DIP) primarily houses integrated circuits (ICs) such as logic gates from the 7400 series and early microprocessors, as well as discrete components including DIP switches, light-emitting diodes (LEDs), and relays. For ICs, the semiconductor die is attached to a central paddle or lead frame within the package using epoxy adhesive, providing mechanical support and thermal conductivity. This die attachment process ensures the silicon chip is securely positioned before subsequent encapsulation.^[41]^[42] Following die attachment, electrical connections are established via wire bonding, where fine gold or aluminum wires link the die's bonding pads to the package leads, enabling signal transmission to external circuits. The assembly is then encapsulated in a protective plastic or ceramic body, sealing the internal components against environmental factors. In contrast, discrete components in DIP formats embed their functional elements directly into the molded body; for instance, DIP switches incorporate mechanical sliders and contacts within the plastic housing for manual configuration, while LEDs feature a semiconductor die bonded to leads and encapsulated for light emission, and relays enclose electromagnetic coils and switch contacts in the body for isolation and operation.^[38]^[43]^[44] Common implementations include the 14-pin DIP for quad operational amplifiers like the LM324, which integrates four independent op-amps on a single die for compact analog signal processing, and the 40-pin DIP for early microprocessors such as the Intel 8080, housing an 8-bit CPU with address and data bus interfaces. These configurations leverage the DIP's standardized pin spacing and footprint for reliable internal connectivity. DIPs are designed for compatibility with insertion into zero-insertion-force sockets during prototyping or direct soldering in production, facilitating versatile device integration without altering external board mounting approaches.^[45]^[46]^[47]

Mounting Techniques

Dual in-line packages (DIPs) are primarily mounted using through-hole technology, where the component's leads are inserted into pre-drilled holes on a printed circuit board (PCB) and secured by soldering on the underside. This method ensures a robust mechanical and electrical connection suitable for applications requiring durability, such as legacy electronics and prototyping. Wave soldering is commonly employed for high-volume production, involving a conveyor system that passes the PCB over a molten solder bath at approximately 260°C with a dwell time of 10 seconds to form joints without excessive heat exposure to the package body.^[48]^[49] For manual or low-volume assembly, hand soldering with a temperature-controlled iron set to a maximum of 350°C is used, limiting contact time per lead to 3-5 seconds maximum and allowing only one pass per lead to prevent thermal damage. Integrated circuit (IC) sockets provide an alternative mounting approach, allowing DIPs to be plugged into a pre-soldered socket on the PCB for easier insertion, removal, and replacement without desoldering, which is particularly beneficial during testing or repairs. Insertion tools, such as plastic extractors or alignment jigs, are recommended for high-pin-count DIPs (e.g., 28 or 40 pins) to prevent lead bending or misalignment during placement.^[49]^[50]^[38] Best practices emphasize pre-mounting preparation, including lead forming to achieve straight, parallel alignment for smooth insertion into PCB holes or sockets, using fixtures to apply minimal force and avoid stressing the package. Anti-static handling is critical to prevent electrostatic discharge (ESD) damage; personnel should ground themselves via wrist straps, and components must be stored and transported in ESD-safe packaging to maintain a common potential and dissipate charges safely. During soldering, no-clean, halogen-free flux is preferred to minimize residue, and preheating the PCB to 100-120°C helps activate flux and control overall thermal profiles.^[38]^[51]^[49] A key challenge in DIP mounting is the heat sensitivity of plastic-encapsulated variants, which can deform or degrade if the body temperature exceeds 260°C during wave soldering or if prolonged exposure occurs in hand soldering. To mitigate this, monitoring with a fast-response thermocouple placed 1 mm from the package edge is advised, ensuring the body remains under 270°C, while selective soldering techniques can target specific leads to reduce overall heat input in mixed assemblies.^[49]^[48]

Usage Conventions

Orientation and Pin Numbering

The orientation of a dual in-line package (DIP) is standardized to facilitate consistent identification and handling. When the package is viewed with its leads facing downward and the body upright, the end featuring a notch, chamfer, or dot mark indicates the location of pin 1, typically positioned at the top-left corner.^[52] This marking convention, established by JEDEC Standard SPP-012, requires a pin #1 identifier at the corner adjacent to pin 1, ensuring compatibility across manufacturers.^[53] Pin numbering in DIP packages follows a counter-clockwise sequence starting from pin 1. For a 14-pin DIP, pins are assigned from 1 to 14, proceeding around the package perimeter, with the left row containing odd-numbered pins (1, 3, 5, 7, 9, 11, 13) and the right row even-numbered pins (2, 4, 6, 8, 10, 12, 14).^[52] This dual-row arrangement aligns with the package's parallel lead rows, spaced at 0.1 inches (2.54 mm) per JEDEC guidelines, promoting uniform circuit board placement. In many integrated circuits housed in 14-pin DIPs, such as standard TTL logic devices, power and ground connections follow conventional assignments to simplify design and reduce noise: pin 14 serves as Vcc (positive supply), and pin 7 as GND (ground).^[52] These assignments are not universal but are prevalent in families like the 74xx series, where they support efficient power distribution across the die.^[52] Datasheet conventions for DIP packages typically include schematic pinout diagrams that depict the counter-clockwise numbering and functional labels relative to the pin 1 marker, often shown in a top-view orientation with the notch upward for clarity.^[52] These diagrams ensure users can map electrical functions to physical pins without ambiguity, aiding in prototyping and assembly.^[52]

Lead Count and Spacing Standards

The dual in-line package (DIP) features lead counts in even numbers ranging from 4 to 64 pins to accommodate various integrated circuit complexities, with the most prevalent configurations being 8, 14, 16, 18, 20, 24, 28, and 40 pins for standard applications.^[38]^[16] These counts ensure compatibility with common socket and board layouts while balancing pin density and mechanical stability. The fundamental spacing standard for DIPs is a uniform pin pitch of 0.1 inches (2.54 mm) between adjacent leads within each row, promoting reliable soldering and electrical isolation.^[7] Row spacing, defined as the distance between the two parallel rows of leads (dimension E in JEDEC outlines), is typically 0.3 inches (7.62 mm) for low- to medium-pin-count packages up to 22 leads.^[7] For higher pin counts, this expands to 0.6 inches (15.24 mm) to prevent lead bending and enhance heat dissipation.^[54] JEDEC specifications govern these dimensions through the MS-001 series for the standard 0.3-inch row spacing family, covering plastic DIPs with body lengths (dimension A) varying by lead count—for example, approximately 0.380 inches for 8-pin, 0.750 inches for 14-pin, and 1.100 inches for 24-pin configurations—and lead spans (dimension E) precisely at 0.300 inches ±0.010 inches.^[7]^[6]^[55]^[56] The MS-011 series addresses wider 0.6-inch row spacing for packages like 24-40 pins, with corresponding body widths (dimension E1) around 0.580 inches to support increased thermal requirements.^[54] These outlines ensure interoperability across manufacturers by specifying tolerances for lead thickness (0.015-0.021 inches) and protrusion. Variations include narrow-body DIPs, where the package body width (dimension E1) is reduced to 0.15-0.2 inches for space-constrained designs while maintaining the 0.3-inch row spacing, as seen in JEDEC MS-001 variants like BB for 16-lead configurations.^[57] For power-handling devices, wider body variants—such as 0.6-inch spacing for 20-pin packages—accommodate thicker leads and better airflow, per MS-011 adaptations.^[58]

Evolution and Alternatives

Advantages and Disadvantages

The dual in-line package (DIP) offers several advantages that make it suitable for specific applications, particularly in low-volume and prototyping scenarios. One key benefit is its compatibility with breadboards and sockets, allowing for straightforward insertion and removal during circuit prototyping without specialized equipment.^[59] Additionally, DIP's through-hole design provides mechanical robustness, as the leads create strong physical bonds to the printed circuit board (PCB), enhancing durability under vibration or stress compared to surface-mount alternatives.^[60] For low-volume production, DIP assembly is cost-effective, relying on manual soldering that avoids the high setup costs of automated surface-mount processes.^[61] Furthermore, components in DIP packages are repairable through desoldering techniques, enabling individual IC replacement without discarding the entire board. Despite these strengths, DIP has notable disadvantages that limit its use in modern, high-density electronics. The package's larger footprint, with pins spaced at 0.1 inches (2.54 mm) and body widths up to 0.3 inches (7.62 mm), restricts component density on PCBs, making it less efficient for compact designs.^[62] Through-hole assembly requires drilling holes in the board and longer soldering times, increasing overall production time and costs, especially in high-volume manufacturing where automation favors surface-mount technology.^[61] DIP is also suboptimal for high-speed signals, as the extended lead lengths introduce significant inductance—typically 5–10 nH per pin—leading to signal distortion, ringing, and reduced performance above a few hundred MHz.^[63] In terms of performance, DIP variants differ by material. Ceramic DIP packages excel in thermal dissipation due to the material's higher conductivity (around 20–30 W/m·K) and ability to handle junction temperatures up to 175°C, making them ideal for harsh environments.^[64] In contrast, plastic DIP packages are limited to operating temperature ranges of 0°C to 70°C for commercial grades, −40°C to 85°C for industrial grades, or up to −40°C to 125°C for extended versions, owing to the lower thermal conductivity of epoxy molding compounds (typically 0.5–1.2 W/m·K for standard compounds).^[65] DIP remains viable for hobbyist, educational, and legacy systems where simplicity outweighs density needs, but its market share is declining in high-volume production as surface-mount packages enable smaller, faster assemblies.^[62]

Descendants and Modern Successors

The dual in-line package (DIP) significantly influenced subsequent integrated circuit (IC) packaging designs, particularly those transitioning to surface-mount technology (SMT) for greater density and automated assembly. Direct descendants include the small-outline integrated circuit (SOIC), introduced by Texas Instruments in 1985 as a compact SMT alternative with a narrower body and 1.27 mm lead pitch compared to DIP's 2.54 mm, enabling reduced board space while maintaining compatibility with existing manufacturing lines.^[66] Similarly, the shrink small-outline package (SSOP), developed in the late 1980s, further miniaturized the form factor with lead pitches below 1.27 mm (typically 0.65 mm), supporting higher integration in consumer electronics and facilitating the shift from through-hole to SMT processes.^[67] Other successors expanded beyond DIP's linear pin arrangement to accommodate increasing pin counts and performance demands. The plastic leaded chip carrier (PLCC), first released in 1976 and standardized in the early 1980s, adopted a square footprint with J-shaped leads on all four sides, allowing up to 84 pins in a smaller area than equivalent DIPs and bridging through-hole and SMT assembly.^[68] The quad flat package (QFP), pioneered by Hitachi in 1977, featured gull-wing leads on four sides with pitches as fine as 0.4 mm, enabling pin counts from 32 to over 300 for microprocessors and logic devices, thus addressing DIP's limitations in high-I/O applications.^[69] For ultra-high density, the ball grid array (BGA), emerging in the late 1980s and widely adopted in the 1990s, replaced leads with an array of solder balls on the package underside, supporting thousands of connections in a compact footprint ideal for advanced computing and mobile devices.^[2] The primary drivers for these transitions were the industry's move to SMT starting in the early 1980s, which gained momentum through the 1990s to enable automation via pick-and-place machines and reflow soldering, alongside demands for miniaturization as IC complexity grew.^[2] This shift reduced manufacturing costs and board real estate by up to 70% in some designs, though DIP persisted in specialized niches like DIP switches for user-configurable settings.^[70] In modern applications, DIP maintains a legacy role in automotive and industrial sectors, where its mechanical robustness and ease of socketed replacement ensure reliability in harsh environments such as engine control modules and control systems.^[71] Hybrid boards combining through-hole DIP components with SMT successors like SOIC or BGA remain common in mixed-technology designs for prototyping and legacy upgrades, balancing cost and performance in non-consumer electronics.^[72]
