 Quality Management for Lead-free Solder Products

Using the Atomic Emission Spectrum (AES) equipment imported from Germany (Spectro Co.,), every batch of lead-free solder product will be carefully checked from the beginning mixing to the finished stage. For all of the lead-free solder products, we could ensure the Pb content is less than 1000ppm and the Cd content is less than 20ppm.

Further, all of our lead-free solder products have the inspection reports provided by the independent third-party inspector, SGS
