TAMURA EC-25 scaling powder
Brief introduction of Tamura Tamura EC-25 flux characteristics;
- Good weldability, suitable for welding with different lead-free alloys such as tin/silver/copper, tin/silver/copper/bismuth and tin/copper.
- This product can eliminate the defects such as non-wetting and continuous welding when soldering printed circuit boards with patches and bulk components.
- Excellent through-hole tin plating.
- Excellent solder extinction performance
- Flux residue is non-corrosive, so the electrical insulation performance of the welded product is excellent.
- No matter foaming or spraying, uniform coating effect can be formed.
