20 Pin ZIF Socket Base

20 Pin Zero Insertion Force (ZIF) Socket Base provides a crucial, reliable connection solution for easily and frequently testing, programming, or debugging 20-pin integrated circuits (ICs) without risking damage to the component leads. This ZIF socket uses a mechanical lever mechanism to open and close the contacts, allowing you to insert or remove a chip with literally zero force, hence its name. You will find this specialized socket essential for design engineers, students, and technicians who handle DIP (Dual In-line Package) components often, significantly speeding up workflow and extending the lifespan of valuable chips.

Key Features:

• Zero Insertion Force (ZIF): The lever-actuated mechanism permits effortless component insertion and extraction, entirely preventing lead bending and damage, which is critical for expensive or sensitive ICs.
• DIP Compatibility: The socket supports a standard 20-pin Dual In-line Package (DIP) IC, accommodating widely used microcontrollers, memory chips, and programmable logic devices.
• High Durability: Engineered for a high number of mating cycles (often ≥ 10,000), making it ideal for continuous use in testing and programming environments.
• Solder Tail Pins: The base features standard through-hole pins for permanent mounting onto a PCB or for use with a prototyping breadboard/adapter.
• Wipe-Action Contacts: The internal contact structure ensures a reliable, low-resistance connection every time the lever closes.

Technical Specifications:

• Number of Pins: 20 (10 pins per side)
• IC Package Supported: DIP-20 (0.3 inch or 7.62 mm row-to-row spacing)
• Contact Material: Beryllium Copper or Phosphor Bronze (Typically Gold plating over Nickel)
• Insulator Material: PPS (Polyphenylene Sulfide) or PBT (Polybutylene Terephthalate)
• Contact Resistance (R_c): Typically ≤ 20 mΩ
• Dielectric Withstanding Voltage: 1000 V AC/minute
• Operating Temperature Range: −55°C to +105°C

Mechanical Specifications:

• Mounting Style: Through-Hole (THT)
• Actuation Mechanism: Cam-Operated Lever
• Insertion/Extraction Force: 0 N (Zero Newton) when lever is open
• Durability (Mating Cycles): ≥ 10,000 cycles (Typical)
• Pin Layout: Standard DIP (2.54 mm or 0.1 inch pitch)

Dimensions:

• Row-to-Row Spacing (IC): 7.62 mm (0.3 in)
• Pin Pitch (Base Pins): 2.54 mm (0.1 in)
• Body Length (L): ≈ 27.9 mm
• Body Width (W): ≈ 12.0 mm (Excluding lever)
• Body Height (H): ≈ 9.8 mm (Excluding lever)

Pinout and Wiring:

• Pin Numbering: Follows the standard DIP convention, starting at pin 1 (marked by a notch or dot) and proceeding counter-clockwise.
• Pin 1 Location: Always located at the bottom-left corner when the lever is positioned on the side, or according to the socket’s designated mark.
• Wiring: Each of the 20 pins connects directly to the corresponding solder tail pin, ensuring a 1:1 electrical connection from the inserted IC to your PCB or programmer board.
• Solder Connection: Use proper soldering techniques for a robust connection to a main board or prototype adapter.

Commonly Used in:

• IC Programmers: Essential interfaces for burning firmware onto programmable microcontrollers (MCUs) and EEPROM/FLASH memory chips.
• Testing Fixtures: Used in QA (Quality Assurance) environments for performing functional or burn-in testing on DIP ICs.
• Development Boards: Integrated into prototyping and educational boards that require quick IC swapping for different experiments or projects.

Applications:

• Microcontroller Flashing: Easily program devices like certain PIC, AVR, or low-pin-count 8051 microcontrollers that come in a 20-pin DIP package.
• Logic Circuit Prototyping: Quickly test different combinations of gates or shift registers in a breadboard setup.
• Fault Isolation: Rapidly swap out suspected faulty ICs during repair or debugging processes to isolate system issues.
