If you are a CEM you are setting yourself up for failure and will be left holding the bag. Flash gold has one purpose. It is a protective coating for the base medal to keep it from oxidizing. It is very thin and will be absorbed into the solder joint

The mechanical centering is used for testing resistors, caps, and other various components. It is also used to center parts by "tapping" them with a set of jaws. When the head picks up the component, it is between these jaws. Each part is setup to
