High filling copper sulfate plating additive for horizontal conveying plating equipment.
A new copper sulfate plating additive has been developed specifically for horizontal conveyor roll-to-roll plating equipment, enabling via filling plating on flexible circuit boards.
In conventional horizontal transport Roll to Roll plating equipment, there was a problem where copper oxidized during the transfer of substrates, leading to a decrease in via filling performance. Our company has successfully developed an additive that incorporates components to control the weak current flowing during inter-cell movement, achieving both good filling properties and throwing power (patent obtained). The high-filling copper sulfate plating additive, Topruchina SVP, enables further densification and multilayering of flexible circuits, making it ideal for improving the efficiency of flexible circuit board manufacturing.
