Board-Level Stacking Header for Tight Pitch Mezzanine Designs
The DF17(4.0)-20DP-0.5V(57): The outer shroud contacts and board guide aid alignment during reflow, while the solder retention features hold the part in place before the paste sets. Mated stack heights of 7mm or 8mm are achieved by pairing this header with the matching DF17 receptacle — the height selection depends on the clearance needed between the two PCBs. Gold contact finish supports repeated mating cycles, making it suitable for assemblies that see periodic disconnect and reconnect.
