Advancements in Conformal Coating Process Controls

Methods for applying conformal coating to Printed Circuit Boards (PCBs) have evolved from the crude dip and spray processes to selective coating. This paper will review the history of process development and how the use of process controls evolved. Quality improvement, ease of use, and system safety are all other benefits attained with process controls that will be discussed in detail. Author: Michael A. Reighard, Nicholas A.
