Frank,

How long have you used this method and satisfied with it's performance, repeatability of SM thickness measurements.   Have you used this tool on populated board and established correlation?

Jean-Francois,

we do our measuring of coating thickness with Coating Thickness Testsystem 
Minitest on a testcoupon.

Hi Technetters,

 

What is the proper method for measuring conformal coating thickness? 
Were're using a micrometer but I doubt that the method is reliable.  A wet 
gauge is not out of the question but we would prefer to measure thickness 
once the coating is cured.

 

Thanks!
