The through-hole termination and push-pull fastening are straightforward for wave-solder assembly.
Mating and footprint considerations
This is an unshrouded header — the 42 pins are fully exposed. The mating half is a Bergstik II receptacle housing (or any 0.100" pitch dual-row socket strip) that provides the keying and retention. The overall contact length of 0.525" (13.34 mm) with a 0.318" (8.08 mm) mating section means the receptacle needs enough depth to fully engage the pins. The 0.107" (2.71 mm) solder tail length is suited for standard 0.062" (1.6 mm) PCBs.
