Hello Doug We don't actually do the insertion. We coat the PCBs, partially cure and supply them back to the customer. Through typical empirical efforts (ie trial and error) we determined long ago the optimum time for sending the coated PCBs depending on the coating itself. For example, a particular acrylic solvent based coating must be press fit the day after we apply the coating. The customer then ensures he does not send them on a Thursday / Friday so we can give him time to place the components. We apply typically 30-40um of coating as again too much coating can cause problems. Interestingly, for a particular material we have to partially bake in our China facility but for the same coating we don't in the UK. This is even though we have air conditioned coating service facilities in China. So, the travel time, conditions of the boards stored etc does make a difference. Doing it this way the customer saves 60-80% of his costs since the labour on masking and de-masking is the really expensive part.

Lee, What do you mean when you say "as long as y ou get the timings right"? Are you inserting through the liquid state or tack free/pre-cure state?

Sent by: TechNet <[log in to unmask]> _____ Hello Steve Our coating services globally do this for a well known connector company for their back planes on very regular basis. Its highly efficient as long as you get the timings right. Let me know what you need to know about it or contact me directly off line to discuss.
