IPC-HDBK-001 w/Amendment 1 Handbook and Guide to Supplement J-STD-001 (Includes J-STD-001B to C Comparison). During fabrication and storage, both components and PWBs will often absorb water. If left in the device, this water will vaporize at solderi

| We have experienced poor adhesion of acrylic conformal coating to plastic bodied IC�s. The observed symptoms of this are a blistering or lifting of the coating at the surface of the component, although peel testing has revealed that this is not al

Good morning Jamie. I work at a CM and can offer some input on process flexability. I do not have any data on how reliable the coating is but I can say that they are both very difficult to control. Will you be selective coating or full coating? Ho

You'd more than likely have repairability issues with the Acrylic based one. The acrylic-based finish is alot harder and more brittle versus the silicone. Some of the new silicones, you can just "peel" with your fingernail, while still getting reli

My guess would be that the adhesive used on the dots contains silicone. We use 1B73 which is also acrylic and it hates silicone. We use silicone RTV to permanently mask around some connectors and unless its fully cured before coating it will cause l

Contact your distributor for the coating or Humiseal directly. Humiseal has had a recent issue with batches of 1B31. The specific problem is lack of adhesion, which is what you have as well. You need to find out if your batch # is one of the affected
