Jim, You may want to consider the use of compliant pin press-fit connectors. They would completely alleviate soldering for these connectors and the associated mating problems. These connectors are available in various types from AMP and other connector suppliers. Ed Harkess Sr. Manufacturing Engineer AMP Packaging Systems [log in to unmask] >>> Jeffery L.

It is necessary to use a mask over adjacent components, and you attach the correct size fountain tool to match component size, but works nicely even for fairly fine pitch connectors. > > ---------------------------------- Jeffery L.
