I have a part that is made out of .005 thick Beryllium Copper with a finish per MIL-G-45204 Type 1 with 5 micro-inches Hard Gold. This part is a surface mount part and attached to the PCB via solder paste then re-flowed. My question is, should I experience any long term reliability or soldering problems with the attachment of this part? Thanking you in advance for your comments.
