latest company case about [#aname#]


Due to environmental concerns, PCBCart 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 PCB manufacturing primarily comes in lead-free solder technology and lead-free components and materials.


As a lead-free PCB manufacturer, PCBCart applies lead-free solder technologies including solder ball formation technology, electro plating technology, solder dipping technology and barrel plating technology, which ensures us 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 bare boards (PCBs) and assembled printed circuit boards (PCBAs).


Furthermore, we select lead-free materials that can withstand 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, we have 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.
