What are the dust prevention measures for recas PCBA processing?
Time:2022-06-30 Read: 187

PCBA processing requires many protective measures, such as dust-proof, moisture-proof, anti-salt spray, anti-static, etc. Today, we mainly understand the dust-proof measures in the PCBA processing process. Anyone familiar with the PCBA industry knows that there will always be various dust-proof measures in the PCBA processing process to prevent dust from adhering to the PCBA circuit board. So what harm will dust cause to PCBA circuit boards? What are the dust-proof measures? Let's take a closer look.


1. The harm of dust to PCBA circuit boards;


Dust is not very harmful to circuit boards. If a lot of dust is attached to the circuit board during the processing process, it is easy to cause short-circuit and other faults, resulting in the circuit board not working properly and reducing the production yield. Therefore, the processing board of the PCBA circuit usually needs to be carried out in a dust-free workshop.


2. What are the dust-proof measures during PCBA processing?


①. Dust-proof clothing: During the PCBA processing process, employees need to wear more slippery dust-free clothing to enter the dust-free workshop to avoid dust contamination on the clothes.


②. Air shower room: When employees enter the clean room, they need to enter the air shower room and rotate their bodies 365° for air shower to further remove foreign objects such as clothing and dust attached to their bodies.


3. Three-proof paint: PCBA is usually coated with three-proof paint during the processing process to further eliminate the harm of dust to PCBA, and can also play the role of moisture-proof and anti-corrosion.


④, vacuum packaging: PCBA will also be vacuum packaged and stored during processing to prevent dust from further adhering to the circuit board.
