Breakaway header for board-to-board stacking — 16 pins at 0.100" pitch
For a 16-pin connector carrying mixed power and signal, budget the total current across the shared temperature rise — the 125°C upper operating limit gives headroom in a 70°C cabinet.
Gold GXT mating surface — 30µinch over nickel for 500+ cycles
The solder tails are tin (78.7µinch) for good wetting during reflow. Phosphor bronze contact material provides a good spring-force retention over the temperature range. The square pin geometry mates with standard 0.025" square receptacles found in matching BERGSTIK sockets or industry-standard IDC connectors.
Surface mount termination — reflow profile and board layout
Termination is solder to surface mount pads — no through-holes, so the board backside stays clear for routing.
