Sn99Ag0.3Cu0.7 Solder

Sn99Ag0.3Cu0.7 Solder

Introduction

This tin silver copper alloy solder wire/bar/rod (Sn99Ag0.3Cu0.7) is also known as SAC0307 lead-free solder. It is applicable for precise LED, mobile phone chips, PCBs, etc. in many hi-tech wave soldering machines and small-sized tin furnaces. With composition of 99% tin, 0.3% silver and 0.7% copper, the lead free Sn-Cu-Ag solders have a high melting point; besides, its lead content is below 100 ppm such as to meet customers’ requirements of environment protection. 




Features

1. Flux content is 2%, the wire diameter reaches over0.15 mm.

2. Our tin silver copper alloy solder wire/bar/rod is produced strictly according to RoHS directive and SS-00259 standards.

3. Two kinds of materials are adopted: the 99.99% refined electrolytic lead and the 99.97% refined quality tin.

4. Lead free Sn-Cu-Ag solders produced by us are popularly sold. They have been exported to countries likePoland,Argentina,Peru,Pakistan,Italy, and so on.
