PCBA It's an empty board （pcb） after SMT Patches and DIP The whole process completed by the plug-in ,( Extended reading ：PCBA Circuit board production process flow ) In the process , Reflow soldering will occur 、 Wave soldering , Manual welding, etc , Because the electronic products are getting smaller and smaller ,PCBA The size requirements of are becoming smaller and smaller , But the requirements for quality （ Including product reliability and stability ） It is getting higher and higher ,

Therefore, many brands or solution providers require smt The patch processing plant is right pcba Apply three proofing paint , Increase the stability and reliability of the product , Ensure product quality and performance , But before the three proofing paint is applied , You have to deal with pcba Clean the plate ,

Because after welding, various flux residues will appear on the board , Some residues are acidic 、 Solubility 、 Corrosivity, etc , If you don't clean the residue , The coating will also cause great damage to the product , Next, Jiangxi Inteli electronic technology will introduce to you pcba Relevant precautions for plate cleaning .

SMT Patch processing pcba Precautions for plate cleaning

1.pcba The plate is welded , It should be cleaned as soon as possible （ Flux residues can produce corrosion over time ）, cleaning pcba Residual flux and other contaminants on the plate ;

2. cleaning pcba Board time , Prevent the cleaning agent from invading the unsealed components , To avoid damage to components , After cleaning , Should be placed in 30-50 In an oven of about degrees , After about half an hour of baking , Take out after drying PCBA plate ;

3. cleaning pcba Board time , Protect the components on the board 、 identification , Otherwise, it will cost you a lot , Waste mounting and welding pcba plate .

cleaning PCBA Boards affect the life and reliability of electronic products , There are some PCBA The board is not cleaned , May cause a short circuit 、 Electric leakage , Lead to unqualified products and many failures , Increase recall and repair costs , So do not clean PCBA The gains outweigh the losses .
