PCBA<\/a> includes components assembly\u00a0and DIP plug-in, in the whole\u00a0process, there will be reflow soldering, wave soldering, manual soldering, due to the current Electronic products are getting smaller and smaller, and the size requirements of PCBA are getting smaller and smaller, but the requirements for quality (including product reliability and stability, etc.) are getting higher and higher.\u00a0Many customers\u00a0require PCBA boards with\u00a0conformal coating\u00a0to increase stability and reliability and ensure product quality and performance. But the PCBA board must be cleaned before with conformal coating.<\/p>\n\n\n\n

Because there will be a variety of flux residues on the soldered MCPCB board, some of which are acidic, soluble and corrosive, etc., if these residues are not cleaned, the coating will also cause very great damage to the product. In this blog I’d like to share some notes for cleaning PCBA.<\/p>\n\n\n\n

  1. PCBA<\/a> board after soldering, should be cleaned as soon as possible (flux residue will produce corrosion over time), cleaning residual flux and other pollutants on PCBA board.<\/li><\/ol>\n\n\n
