Everyone who is involved in PCB industry knows that PCBs which have copper finishes on the surface require a protective layer to protect it against oxidation and deterioration.

2 years ago, we received a request from our customer, they were looking for a coating solution which produces a fine gold and bronze colors on the copper PCBs which is used for 5G SIM card, social security cards and smart cards module. We spent 6 months in R&D, made over 20 experiments to finalize the proper coating processes. In March 2020, we delivered the machine to customer’s site with great satisfaction.
