This 44-pin through-hole PLCC socket provides a dedicated solderless interface for 44-lead square J-lead IC chips on printed circuit boards. It allows engineers to mount and replace microcontrollers, CPLDs, and custom ASIC processors without soldering heat, eliminating thermal risks during assembly and testing. The socket is widely used on industrial automation controllers, embedded development boards, and automotive electronics.
Key Features
- Available Positions: Standard options in 20, 28, 32, 44, 52, 68, and 84 pins.
- Mating Pitch: 1.27 mm (.050″) pitch for 44-lead J-lead PLCC packaged chips.
- Board Termination: Converts fine-pitch IC pins to a 2.54 mm (.100″) through-hole grid.
- Mounting Style: Vertical through-hole wave soldering with standard tail length.
- Solderless Swapping: Protects chips from soldering heat and enables fast field replacement.
