ROHS/Lead Free in PCB Manufacturing
WellerPCB as a China Printed Circuit Board manufacturer and your offshore PCB Manufacturer has several years of experience successfully manufacturing PCB’s that are RoHS compliant and are compliant with lead-free assembly. We offer a variety of laminate and surface finish options.
Due to environmental concerns, WellerPCB provides PCB fabrication and assembly services conforming to RoHS regulations that require rigorous concentration of 6 hazardous substances including Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr VI), Polybrominated Biphenyls (PBB) and Polybrominated Diphenyl Ethers (PBDE) in the manufacturing of electronic and electrical products. Among the 6 types of substances, lead is the most widely applied as it plays a fundamental role in electronic plating. Therefore, lead-free solutions are the optimal prescription for RoHS-compatible PCB assembly.
Generally speaking, lead free manufacturing primarily comes in lead-free solder technology and lead-free components and materials.
As a lead-free PCB manufacturer,WellerPCB takes advantage of solder ball formation technology, electro plating technology, solder dipping technology and barrel plating technology all of which belong to the family of lead-free solder technology. These solder technologies ensure our increased capabilities to successfully deal with problems, tin whiskers for example, that affect reliability of products and to implement lead-free surface finishes like HASL, ENIG, ImAg, etc. on PCBs and PCBAs.
Furthermore, it is of much significance to select lead-free materials that are capable of withstanding high temperature as replacement of traditional solder material. Moreover, flux in lead-free solder should be much more active than the rosin flux in traditional solder.
In addition, components involved in lead-free PCB assembly have to meet the requirements for lead-free compliance accounting for reliability and suitability of final products. Owing to more than 10 years’ experience in this field, WellerPCB has maintained such long-term and friendly cooperation relationship between renowned component manufacturers and distributors around the world that we’ re capable of procuring high quality lead-free components for our customers filled with environmental concerns.
