TAMURA EC-19S-A scaling powder
Brief introduction of Tamura Tamura EC-19S-A flux characteristics;
- It has good weldability and can be used 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.
- Because this flux is extinction flux, the welding surface after welding is even extinction, which is convenient for visual inspection in the latter part of welding.
- Excellent tin plating on through holes
- There is little flux residue, and the color of the product is close to transparency, so the substrate does not stick to hands after welding.
- Excellent solder extinction performance
- The flux residue is non-corrosive, so the electrical insulation performance of the welded product is excellent.
- Uniform coating effect can be achieved by foaming or spraying.
