I can't add much to Joe's suggestions however what I can add is:

The B52 incorporates some thru-hole connectors so that you can also run
wave soldering if that is part of your process. It is certainly here
that I would first expect there to be any problems.

The B52 has a cousin: the TB57 that features in the International
Standard IEC 61189-5. This was a design that originated at NPL in the UK
and from which Doug "tweaked" to create the B52. He loves to do that -
tweaking that is!

There is a fast growing data set on this and, on behalf of the SIR TG at
IPC, would ask that you share your results with us if you do go down
this route? We can keep it anonymous to protect the innocent....

Kindest regards
Graham Naisbitt
Managing Director
