Ultrasonic and air bubble in plating bath


I want to reduce the non-plating problem caused by air or hydrogen bubble in nickel plating bath for PCB.

My Question is:

1. Is ultrasonic effective to separate bubble from the metal surface?

2. Can in affect any property of plated metal layer?

Thank you,

I don't think you want ultrasonics (it actually creates bubbles). Try adding a surfactant to the bath; you can probably purchase it from your nickel bath supplier.

The answer is yes to both. The bubble gets broken down by the ultrasonic and increases plating speed substantially. The coating is much harder (I haven't measured it so I can't commit).

This may aggravate the problem actually for your PCBs with faster edge build up on your holes. I have used Reverse pulse plating to great advantage and I would say that is the way to go.
