TAMURA EC-19S-8 scaling powder
Brief introduction of Tamura Tamura EC-19S-8 flux characteristics;
- Uniform coating effect can be achieved by foaming or spraying.
- The flux residue is non-corrosive, so the electrical insulation performance of the welded product is excellent.
- 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.
- EC-19S-8 has good weldability, and can be used for welding 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.
