What are the usage processes of the three proofing paint? Now let the editor take you to understand.
1. Automatic dip coating - dip coating ensures complete film coverage and does not cause material waste due to excessive spraying.
2. Spraying - the use of spray can type products can be easily applied to maintenance and small-scale production. The spray gun is suitable for large-scale production, but these two spraying methods have high requirements for the accuracy of operation, and may produce shadows (where the lower part of the components is not covered with three proofing paint).
3. Brush coating - widely used and can produce excellent coating effects on smooth surfaces.
4. Selective coating - Accurate coating without wasting materials, suitable for large-scale film covering, but with high requirements for coating equipment. Most suitable for large-scale lamination. Using a prepared XY table can reduce masking. When painting PCB boards, there are many connectors that do not require painting. If the adhesive tape is too slow to apply and there is too much residual adhesive when tearing, consider making a combination cover according to the shape, size, and position of the connector, and positioning it with installation holes. Cover areas that do not require painting.
The above are the four major usage processes of the three proofing paint that I will introduce to you.
