The circuit board is mainly composed of pads, vias, mounting holes, wires, components, connectors, filling, electrical boundaries, etc. The circuit board makes the circuit miniaturized and intuitive, which plays an important role in the mass production of fixed circuits and optimizing the layout of electrical appliances. The circuit board can be called a printed circuit board or a printed circuit board. The export of circuit boards to the EU requires environmental ROHS testing.
RoHS certification is also called environmental certification, which is in line with European and American standards. It is the abbreviation of \"The restriction of the use of certain hazardous substances in electrical and electronic equipment\" (The restriction of the use of certain hazardous substances in electrical and electronic equipment). It stipulates that if lead, Pb, Imports of harmful heavy metals such as cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated diphenyl ethers PBDE and polybrominated biphenyls PBB have been banned by the EU from July 1, 2006.
With the widespread use of lithium batteries in mobile communications, electronic appliances and other fields, safety accidents caused by lithium battery explosions are not uncommon in recent years.
