Problems solved by technology

[0002] Printed circuit boards, also known as printed circuit boards, are providers of electrical connections for electronic components. Due to the dense distribution of circuits and parts on the surface, some dust, fingerprints and other residues left during the preparation of printed circuit boards are not easy to Clean, if the dirt accumulates too much, it will easily affect the use of the circuit board
