40-Pin Wire Wrap IC Socket – 0.6" Wide (DIP-40), Gold-Plated Machined Pins with Extended Square Posts for High-Reliability Prototyping

The 40-Pin Wire Wrap IC Socket is the definitive choice for engineers and researchers developing large-scale digital systems or restoring iconic 8-bit and 16-bit computer hardware. Wire wrapping is a specialized point-to-point wiring technique that eliminates the need for a custom PCB during the development phase. This 40-pin variant is an industry standard for "large" microprocessors and specialized interface chips that require a robust and flexible mounting solution. A primary advantage of these machined sockets is the "closed-bottom" design of the pins. This prevents any solder or flux from wicking up into the contact area if the base of the posts is mounted to a carrier board. The extended square posts are specifically engineered to accommodate up to three separate wraps of 30 AWG Kynar wire, allowing for incredibly complex logic signal routing on a single pin without cross-talk or interference. Whether you are prototyping a complex industrial controller, building a custom Z80/6502-based computer, or developing a high-reliability aerospace module, these 40-pin sockets provide a professional-grade foundation. They offer the modularity of a breadboard with the long-term electrical durability of a hard-wired system.

Key Features:

Machined 4-Finger Contacts: Equipped with precision-turned internal contacts that provide a high-pressure, multi-point grip on IC leads for superior vibration resistance and signal stability.

Gold-Plated Signal Integrity: The inner "fingers" are gold-plated to prevent oxidation and ensure ultra-low contact resistance throughout the life of the prototype.

Standard 0.6" Row Spacing: Designed for "Wide" 40-pin DIP (Dual In-Line Package) components, perfectly fitting high-performance microcontrollers (like the ATmega16/32 or PIC16F877A), 8051 variants, and legacy CPUs.

Gas-Tight Reliability: The sharp corners of the square posts create a gas-tight electrical bond when wrapped, providing a connection that is often more reliable than solder in high-vibration or extreme-temperature environments.

High-Durability Housing: Molded from glass-filled polyester (PBT), ensuring the socket remains stable under thermal stress and mechanical insertion forces.
