[0002] Circuit boards, commonly known as PCBs, are an indispensable basic component in modern electronic devices. They achieve electrical connections between electronic components by printing or etching conductive paths on insulating substrates. Circuit boards can assemble electronic components together in an orderly manner to form complex electronic circuits, thereby ensuring the normal operation of electronic equipment. On circuit boards, conductive paths are usually made of copper materials, while insulating substrates may be made of phenolic resin, epoxy resin or other high-temperature resistant materials with good insulation properties. Circuit boards can be divided into single-sided boards, double-sided boards, multi-layer boards and other types according to different manufacturing processes and application scenarios.
