Product Description
This board-to-board PCB connector is designed for compact, high-reliability signal transmission between stacked or parallel circuit boards. A single row of gold-plated mating pads provides stable, low-loss contact for digital and analog signals, while tin-plated solder tails ensure strong mechanical retention and easy assembly onto standard PCBs.
The high-temperature, UL94V-0 housing maintains dimensional stability during reflow or wave soldering and offers excellent insulation performance in harsh industrial and automotive environments. Flexible customization of pitch, pin count and connector height allows the design to be adapted to different control boards, communication modules and power-assist circuits.

Precautions
Design PCB pad layout according to the recommended footprint to guarantee correct coplanarity and solder joint reliability.
Do not exceed the specified current and voltage ratings; apply suitable derating in high-temperature or densely packed enclosures.
Avoid twisting or side loading when mating and unmating; always align boards before pressing to prevent bent terminals.
Keep the gold mating area clean and free from flux, dust or oil to maintain low contact resistance and stable signal quality.
For applications with strong vibration or shock, combine this connector with mechanical board supports or screws for additional reinforcement.
