What are the Ways to Coat PCBA with Conformal Coating
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...
