What are the operating requirements for PCBA conformal coating?

Hits:1  Add Date:2021/6/25

1.The coating work of the conformal coating should be carried out in a separateroom, but it should not be completely airtight, and there must be goodventilation facilities.

2.Smoking, eating and drinking are prohibited in the operation room, andalcoholic beverages should not be used before work.

3.Wear masks or gas masks, rubber gloves, chemical protective glasses and otherprotective equipment during operation to avoid harm to the body. This alsodepends on the selected three-proof paint product. If it contains stupidproducts, pay great attention to protection. And fireproof, and if it is aTIS-NM environmental protection conformal coating product, the safety is muchhigher and there is no risk of burning.

4.After the work is finished, clean the used utensils in time, arrange and testtools and equipment, and cover tightly the container with the conformal coating.

5.The workplace should be clean and dust-free, and there should be no flyingdust, and irrelevant personnel should be prohibited from entering.

6.Tools and equipment should be fully grounded, and electrostatic protectionmeasures should be taken.

7.Do not overlap PCBA during operation; PCB boards should be placed horizontally.

8.Before using each batch of raw materials, a small sample curing test (3-5PCS)should be done.

9.Clean and bake the board to remove moisture and moisture. The dust, moistureand oil on the surface of the object to be coated must be removed first, sothat it can give full play to its protective effect. Thorough cleaning canensure that the corrosive residues are completely removed, and make the conformalcoating adhere to the surface of the circuit board well. Drying conditions: 60<span style=""font-size:12.0pt;font-family:宋體;mso-ascii-font-family:"Times New Roman";">°C, 10-20 minutes,take it out of the oven and apply it while it is hot, the effect will be better.
