Can anyone tell me if there is a reference for smt component height specs on the bottom side of a board, which will also go through wave soldering. A current design I am reviewing has tant caps(7343) and a crystal on the back side. Should I only be

You said your gold processing is immersion. More importantly, what is the process used for your nickel? Electroless correct? What is the percent by weight of phosphorus found in your analysis? How many times was the nickel plated? [You should be a
