Bar Solder

Dross Comparison of KI/KEWEI New Electropure Bar vs. Competitors

500 pounds of each type of alloy was heated in a wave solder pot at 500°F for 6 hours.  

The pot was de-drossed every 3 hours.  After 6 hours the amount of dross generated from each type of solder was weighed.

KI/KEWEI Solder bar solder has proven to reduce drossing as compared to competitive brands.

Zero defect wave soldering requires consistent solder quality. 

Contaminants and high oxide levels in bar solder can result in a variety of wave soldering defects such as bridging, projections, and poor wetting. 

To avoid these issues,  our low drossing solder bar alloys provide a high purity product exceeding IPC, JEDEC and IEC requirements.

Our solder bar is processed from high-quality, virgin metals in a proprietary method that removes contaminants and reduces dissolved oxides. 

And the technique results in an extremely pure, low-drossing solder bar that increases throughput and decreases defects.
