What are the different types of PCB connectors?

Learn PCB connector types: board-to-board, wire-to-board & wire-to-wire + rugged options. Select by environment, space, assembly to prevent failures & save troubleshooting time.
Which is better, HASL or ENIG?

HASL is cheaper upfront for simple PCBs. Choose ENIG for fine-pitch HDI designs, long-term reliability, or high-speed signals to avoid costly reworks and signal loss.
