Hi again, I forgot to ask if you were cleaning your boards ? Is so what is your process and media ? Leigh Jansen (Mr) Technical Support Manager Concoat Limited - Engineering Electronics Reliability -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Lance Mayes Sent: 10 June 2004 00:18 To: [log in to unmask] Subject: [TN] Conformal Coating Importance: High Hello again Techies; We are having issues with our conformal coating on some of our components. It pulls back from some of the components leads along the edges. We are wondering if this will make a difference in the protection of the board. We're using Humiseal Acrylic 1B31 and Humiseal Thinner 521 in a mixture. The conformal machine sprays a nice coating and then the coating starts to recede. Sometimes this happens even when we paint the acrylic manually. Has anyone else ran into this problem, and what to do to overcome it? This is a good one for the end of the day. I'll be waiting. Thanks again P.
