| We have developed ES-CuO as a copper products
for plating of printed circuit board (PCB). We collect waste etching
solution, separate a copper and refine it through chemical processes
for the production of ES-CuO. We provide the complete chain of
recycling as follows. |
| - |
ES-CuO is mainly used for a plating
system used an insoluble anode with following features. |
| - |
ES-CuO is copper oxide powder, dissolving
quickly and easily. |
| - |
Less residue and high purity. |
| - |
Able to preserve the composition of
a solution uniform. |
| - |
Excellent fluidity and low dust makes
preventing filter from clogging. |
| - |
No need for replenishing and bathing
works associated which are enabitable copper ball. |
| - |
PCB industries (through hole plating/vias
filling) |
| - |
Decorative plating on plastics |
