Hi Dave, Sorry about that. Specifically, I am referring to radial leads on a crystal. The leads are supposed to be gold plated but only 1/2 to 2/3 of the lead is plated. We bend the lead to form a foot which is soldered to a pad on the PCB. Normally

To be honest this product its only a part of bigger PCB, so we have only substrate with 3 FETs on it so no other components at substrate occurs and all substrate are staying at metal fixture. WE have already window pan aperture. WE producing this pro

Our design group is looking at using a IMPCB material for a power amplifier design. They would like to to use this because of it's excellent thermal properties. This would be used to create a "SIP" module that would plug into a std FR4 pcb with the c
