Werner,
Thank you for your response. The part is not bare Beryllium Copper
but is finished per MIL-G-45204 Type 1 with 5 micro-inches of Hard Gold. We
are experiencing some of these parts coming off the PCB from vibration
during shipment to us from our sub-contract assembly house. We are looking
at all options and wanted to solicite other options.
Best regards,
Wes

Hi Wes,
Beryllium Copper has a long history with people having problems soldering to
it.
My advice: solder some and pull them off, if the break gives you a smooth
impression of the BeCu surface in the solder, you have poor or no wetting.
