Lesd-free solder wire

Lesd-free solder wire(1)

From the selection of high-quality pure tin to strict process monitoring, to the finalThe product delivery inspection fully ensures the best weldability of lead-free tin wire and its productsQuality, in the EU ROSH directive two hazardous substances lead (Pb), chromium (Cd)The content is far below the international standard. Comply with RoSH, REACH, etcRelevant regulations.
