Board-fit and routing check
In a quarterly maintenance schedule, that gold thickness translates to decades of reliable contact before the underplate sees wear. The post-side is tin-plated (39.4 µinch), which is the standard for solder-joint compatibility with SAC305 reflow profiles.

The latch is audible on full mate; if it does not click, the pair is not seated. The insulation height of 7.30 mm gives the mated pair a low profile above the board — useful when the cable bundle routes close to the PCB surface.
