The RoHS Directive, adopted by the European Union, helps regulate the use of hazardous materials in printed circuit boards.
RoHS prohibits the use of mercury, lead, polybrominated biphenyls, etc., in the manufacture of printed circuit boards.
Lead-free PCBs have better thermal properties than lead-containing boards, making them more efficient and stable in operation. In addition, avoiding lead and other hazardous substances reduces environmental pollution and the risk of metal poisoning.
When selecting PCB materials, manufacturers must consider RoHS material characteristics such as moisture absorption, glass transition temperature, delamination time, and coefficients of thermal expansion. The reliability of printed circuit boards and the quality of their production depend on the correct selection of RoHS materials and consideration of these properties.
