Conformal Coating Facility Setup: General Requirements

Posted by Sean Horn on Mon, Aug 06, 2012 @ 12:23 PM

We get a lot of requests from customers looking to keep their conformal coating an in-house process.  A lot goes into the conformal coating process, so it may be easy to overlook allThe coating room area should be clean and dust free since printed circuit boards are especially susceptible to particles sticking to the drying coating.  The temperature range should be reasonably controlled within the sensible limits since the visocity of the coating is dependent upon the temperature.  However, a more critical point than temperature is the humidty which needs to be controlled to be above 35% for ESD reasons and <55% due to moisture issues which can affect the coating integrity and the application method.
