John Gulley:

Vibration equipment is becoming more and more common today on both electroless 
copper and electroplating tanks. Typcially a frame is mounted on the tank on 
vibration isolators and the plating rack and vibrator motor are mounted on the 
vibration frame. Cost depends on the size of your tank and the weight of your 
loaded plating rack. You could spend $1000-2000 per tank getting the right frame
and vibrator motor. We have found that the vibrator frame design is critical to 
optimizing the vibration effect and we have also learned that the mounting of 
the vibrator motor is critical to the life of the motor.

One source of Vibrator motors is:

Address,

No PUN intended.

Does anyone have experience in using external solution vibrators 
in Wet area Processes?  Ultrasonics is out of the question, due to 
cost.  Direct attachment of vibrators to the plating tanks is out 
of the question, since we are using polypropylene tanks.  

For the past several weeks I've been evaluating Teflon and some 
new chemicals by manual vibration (a hammer to the plating racks). 
I now know this works, but who and where do I get the vibrators 
from?  And what type of cost are we looking at?  

Can someone advise immediately.  I would like to continue my 
evaluations with automated vibrators.
