These days customers have been receiving calls asking how to put coated PCB circuit board conformal coating repair, today, let us take the next discuss this issue. The method has been applied to repair the devices usually have three ways to repair, cleaning solvents, except machinery and high-temperature paint coating dissolved: If you have already coated device repair, simply soldering soldering iron can be removed in direct contact with the coating components . Then install the new components, and then clean the area with a brush or solvents; may also be solvent cleaned; After drying re-paint coated well. Environmental and safety precautions when a coating, the coating operation should not be less than all 16 ℃ and 75% relative humidity above conditions. PCB as composites, moisture absorption. If not tide, conformal coating can not be adequately protective effect. Pre-dried, and dried in vacuo to remove most of the moisture. 2, part of the conformal coating products containing flammable solvents; should avoid high temperatures and avoid flames; should have adequate ventilation to facilitate gum solvent evaporation and fast curing; avoid prolonged or repeated inhalation of vapors and contact with the skin for a long time; After curing the workpiece is essentially harmless. Attention to safety and protective coating operations, the environment should be well ventilated, employees should wear protective masks. 3. When part of the product by contacting moisture in the air to cure. The higher the moisture content in the air, the faster the drying and curing of the layer; higher the temperature, the faster the curing layer (but not more than 80 ℃). 4, run out of the brush, airbrush, etc. should be promptly cleaned with thinner to prepare for the next reuse. 5, after pouring plastic bottle, the bottle should be a clean eraser Department, tighten the cap, save seal shade. When used again, if the seal a little crust, its removal can not affect the normal use. If you want to know more information, please visit (PCB conformal coating http://www.sanfangqi.com) Website
