All,

The IPC draft IPC-4553 spec listed below mentions two types of valid
silver plating.
Thin 3-5 micro inch and Thick as 8-12 micro inch.

What are board fabricators typically using Thin or Thick?

Also, I saw a presentation from a board shop  recently
with Silver thickness up to 25 micro inch.

It that too thick?

What is too Thick?

Thanks in advance,
Dave Seymour
