Welllllll, it depends. Define "not a concern". I have had some instances
where the coating on connector pins was too heavy, but in all honesty that
was during the "I have no damn idea what I am doing" phase. Once you get
the parameters dialed in, then no, but take that with a grain of salt. It
may depend on whether you spray it on or dip coat (as I have). If dip
coating, the applied film thickness is related to withdrawal speed from the
bath. You can never really separate a manufacturing material from its
manufacturing process.
