28 Pin ZIF socket
This content will be shared across all product pages.
A 28-pin ZIF (Zero Insertion Force) socket is specifically designed to accommodate integrated circuits (ICs) with 28 pins, typically in Dual In-line Package (DIP) format. The ZIF socket is renowned for its ease of use, allowing ICs to be inserted and removed without applying any significant force, thus minimizing the risk of damage to the IC or the socket itself.
Key Features:
- Compatibility: Supports 28-pin DIP ICs.
- Insertion Mechanism: Features a ZIF mechanism that facilitates easy insertion and removal of ICs.
- Operating Principle: Uses a lever or slide to open and close the socket contacts, securing the IC in place when engaged.
- Contact Material: Typically employs gold-plated contacts for optimal conductivity and corrosion resistance.
- Material: Constructed from durable materials to withstand multiple insertion and removal cycles.
- Mounting Options: Can be mounted on a PCB using through-hole or surface-mount techniques.
- Applications: Ideal for prototyping, testing, and applications requiring frequent IC changes without soldering.
- Pin Count: 28
- Pin Pitch: Standard 2.54 mm (0.1 inches) pitch.
- Socket Type: Zero Insertion Force (ZIF).
- Contact Material: Gold-plated contacts for enhanced conductivity.
- Housing Material: Typically made from high-temperature resistant plastic.
- Dimensions: Designed to fit standard 28-pin DIP ICs.
- Prototyping and Development: Enables rapid swapping of ICs during design iterations.
- Testing and Debugging: Facilitates easy replacement of ICs for troubleshooting purposes.
- Education: Used in educational settings to teach about IC handling and circuit design.
- Repair and Maintenance: Simplifies the replacement of ICs in electronic equipment.
