It seems similar "more" towards IPC 620...soldering wire to solder cap/pin. The joints seems good but you have to ensure mechanical stress relief is designed within the whole module where these boards are installed.

Hi James,

We want to avoid installing the straight lead directly to a PCB pad.  Due to the mechanical construction of the housing, we cannot form the leads prior to pin installation (nor after) to add stress relief.  The only other option is to use "jumper" wires between the pin and PCB, which is more labor intensive.

Thanks,
Adrian

Can I ask why you are doing it this way?  Is for mechanical reasons or a component that's fitted after solderbath?

James
