HOW DOES IT WORK:
For Sodium hypophosphite monohydrate reduction electroless copper plating and other electroless copper plating processes, they have the same chemical principle.
Sodium hypophosphite monohydrates essence is also an electroless copper plating method to reduce the free copper ions in the copper plating solution to solid copper crystals and plate them on the surface of the substrate with the help of a suitable reducing agent.
Nowadays, the electroless copper plating process for Sodium hypophosphite monohydrate reduction is very similar to the electroless copper plating process for formaldehyde reduction, but the reaction mechanism is much more complicated.
This is because pure metallic copper has no catalytic activity for the oxidation reaction of sodium hypophosphite.
When using Sodium hypophosphite monohydrate as a reducing agent for electroless copper plating, Sodium hypophosphite monohydrate cannot achieve an autocatalytic electroless plating reaction through the copper particles and silver particles produced in the activation and sensitization stages like the formaldehyde system.
To make the electroless copper plating reaction of the sodium hypophosphite system continue, Sodium hypophosphite monohydrate is necessary to add a substance with catalytic activity for the electroless plating reaction.
The current way to solve this technical problem is to learn from the process principle of electroless nickel plating.
Nickel ions are added to the plating solution, and a copper plating layer containing a small amount of nickel is obtained through the co-deposition of metallic nickel and copper.
The deposited nickel particles can catalyze the reaction of sodium hypophosphite reducing Cu2+, so as to ensure the continuous progress of the electroless copper plating reaction, and finally obtain a high-quality copper coating.
