It is the main compound for acid copper plating and the source of Cu2+In the plating solution. The JHD copper sulfate is processed so that metallic ions and organic impurities affecting the plating bath's perfomance can be removed effectively.
Due to its high quality and direct usability without treatment, it can be used for plastic plating, electroforming finishing, PCBs, electronic contacts, chemical copper plating, microelectronic interconnection technology and encapsulation.
The key to process stability is to select high-grade plating materials.
Properties:
Density=2.2844g/cm3, Toxic; Metallic acerbity smell; the aqueous blue solution has weak acidic properties.
At 150 degrees centigrade, it loses its moisture and becomes a white powder (Copper sulfate anhydrous). At 650 degrees, it diffuses into copper oxide and sulfur trioxide.
Advantages:
1. Our advance production process ensures that our product has a high content of copper, low metallic ions,
chloride and organic impurities which guarantees high stability.
2. Our product can be used directly in the supplementation of copper salt in both the bath cleaning and the
production processes. As there is no need to deal with the impurities, it leads to economization and stability.
3. Our product dissolves quickly without bubbling effects in the dissolution process.
