52-Pin PLCC Socket – High-Density Surface Mount (SMT) or Through-Hole (TH) IC Adapter, J-Lead Reliable Interface for Microcontrollers and PLDs

The 52-Pin PLCC Socket is an essential component for engineers and developers working with specialized integrated circuits such as 16-bit microcontrollers, complex programmable logic devices (CPLDs), and older-generation memory controllers. By using a socket instead of soldering the chip directly to the board, you allow for easy firmware chips swaps, simplified troubleshooting, and protection for sensitive silicon from the thermal stress of production-line soldering. The internal contact geometry is precision-tuned to accommodate the "J-bend" leads of a PLCC-52 package. This design ensures that all 52 pins maintain solid electrical contact even as the device ages or experiences mechanical shock. The socket’s construction facilitates the use of a standard PLCC extraction tool, which is highly recommended to avoid damaging the socket’s sidewalls or bending the internal spring contacts during chip removal. Whether you are building a prototype for industrial automation or maintaining legacy hardware, the 52-pin PLCC socket provides a robust, professional-grade mounting solution. It bridges the gap between the flexibility of a socketed design and the space-saving benefits of modern surface-mount technology.

Key Features:

Polarized Orientation: Features a distinct chamfered (angled) corner that corresponds to the Pin 1 indicator on the IC, ensuring correct alignment and preventing circuit damage.

High-Retention Spring Contacts: Equipped with tin-plated phosphor bronze contacts that maintain consistent, high-pressure force against the J-leads for a vibration-resistant connection.

Open-Bottom Frame: Designed with a center aperture to improve thermal dissipation and allow for easy inspection of the PCB surface and solder joints beneath the socket.

High-Temperature Performance: Molded from glass-reinforced thermoplastic (PPS or PBT), making it compatible with standard industrial reflow or wave soldering temperatures.

Space-Saving Footprint: Maximizes PCB real estate by utilizing a square geometry that mirrors the compact dimensions of the PLCC-52 package.
