We produce various solder preforms for micro assembly, the category covers more than 100 kinds of alloy such as Au80Sn20、Sn42Bi58、In97Ag3 etc.
And we are capable to provide standard and customized solder preforms with different noble metal alloys, sizes, and shapes to satisfy our customers’needs.
PACKAGING
To protect the solder preforms during shipping and handling, we provide designed packs, like VR pack, Waffle pack, Tape & Reel, Jar or Bulk pack etc.
