      PCBA conformal   coating   is a kind of protective coating, which will form a transparent protective film after curing to protect PCBA from environmental erosion.   PCBA  factorie s generally classify the types of PCBA conformal coatings according to the solvent content.       1.  Solvent -based   Conformal  Coating Solvent-based conformal  c oating  is a coating made of organic solvents as a dispersion medium, and it is also the type of conformal  c oatings used most by PCBA  factorie s .   Solvent-based conformal   c oating   has the advantages of good protective effect, cheap price, and easy repair. Its disadvantage is that it contains volatile toxic gases.     The solvent types of solvent-based conformal coatings mainly include hydrocarbon solvents, oxygen-containing solvents and water solvents. 1.  Hydrocarbon solvents are mixtures of materials of different molec...

       Conformal coating is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion. In addition to anti-mildew, anti-salt spray and anti-humid heat, it also has many functions such as dust-proof, anti-aging, insulation, etc., which plays a vital role in enhancing the reliability and service life of PCBA boards. Different coating methods are suitable for different processing scenarios, so what are the ways to coat PCBA with conformal coating?       1.  Spraying Spraying is the main coating method of conformal coating at present, which is divided into manual spraying and machine spraying. Among them, machine spraying belongs to the automatic spraying method, which is automatically sprayed by the machine, which has the advantages of uniform spraying, high efficiency and automatic detection of spraying effect.  The disadvantage is that some blocked corners cannot be sprayed, such as the posi...
