When I said "In this area, there is no difference between your experience in ceramic substrates and PTFE substrates." I was referring to the area we were discussing ... gold plating. I am sorry if you thought I ment than the wire bonding process wa

Thanks Chris. As I was writing my last message our mailperson dropped off the latest issue of Circuit Assembly. It has an article on mixing SMT and COB on the same board. The author recommends as a compromise 10-20 micro inches of gold over 70-100 of

For soldered areas, we like to keep gold thickness substantially below the maximum you propose. Search the fine SMTnet Archives for our discussions on the topic of acceptable levels of gold with solder connections. Let�s fix this �no one seems be s

What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

ENEPIG or Imm Pd? Concerns about palladium as a solderability protection are: * Palladium is more difficult to process in fab than gold * Palladium solder alloys can be brittle, similar to gold, without proper soldering process and/or specification/
