The criteria below is what we use in our internal conformal coating document. If you can't see the criteria below please let me know and I can forward it to you directly.

I am look at Class 3 and I am loss on its interpretation, especially 'Voids or bubbles'. Acceptable - Class 1, 2, 3 No bridging of adjacent lands or conductive surfaces from : * Loss of adhesion (mealing) * Voids or bubbles * Dewetting * Cracks * Ripples * Fisheyes or orange peel It is common to find bubbles trapped between the soldered leads of those gull-leaded components and between closely mounted SMDs passives for brushing method. Are these bubbles allow for Class 3?
