Sn Cu Solder

Sn Cu Solder

Introduction

As lead free product, Sn-Cu alloy solder has replaced the lead solder and widely works for soldering electronic elements and fix the silicone products. This tin copper alloy is made up of 99.3% tin and 0.7% copper (Sn99.3Cu0.7) and has the melting point of approximately 227 degrees Celsius. Sn99.3Cu0.7 is available in both wave soldering and dip soldering, because it is eco-friendly and meets high demands for environmental protection.      

  


                           


Hazardous Chemical Elements in Sn-Cu Alloy Solder
1. Lead (Pb)
In each kind of homogeneous material, the amount of lead is less than 0.1% by weight.
2. Mercury (Hg)
The amount of mercury in each kind of homogeneous material is less than 0.1% by weight.
3. Cadmium (Cd)
In each homogeneous material, the amount of cadmium is less than 0.01% by weight.
