Yes, you must thin Dow CC for any spray operations. We use Dow 2577 daily for multiple customers and we always thin it for spray operations and 2577 is considered medium viscosity. Dow recommends using up to 60% solvent (Xylene). Your 2620 is low vis

At this time we will be hand spraying acrylic, probably using spray cans until we decide on a spray gun or an air brush, and get one ordered. Our volume is too low to even consider an automated system. Our current requirement is on an item designed

are you going to clean the boards prior to coating?

Hi Cecil, We using conformal coating in our manufacturing area, we did use to use Humiseal, others have been Bectron and Peters. We recentalt switched all lacquering to Peters, since it is lead free and it is a lot friendly than Humiseal. To answer

Does anyone have any input on the need to bake out an assembly prior to the conformal coat process? I understand baking out components/pwb's prior to processing through the reflow or wave solder process if the material shows excess moisture absorbtio

Hi! We have both Dip & Spray conformal coating processes & have never done any kind of baking before the process! I am assuming the reason for baking would be the same - ie, remove any moisture on the brds since moisture will create failure of the co

Tell them every action taken with the boards carries risk of damage. Process steps that don't do anything should be avoided because they carry the risk of causing defects. Even inspection causes the occasional defect, and board handling in general s

Stephen, If you have ever gotten QC to buy into this logic you have a much better QC department than most. Jerry
