Base on the PORON foam rubber recommended, is it possible to apply on small BGA chip of 4x4 ball size 0.3mm. Any specific part no and supplier for this type of foam and is it a anti-static material? Would it be possible to punch out at dia. 3mm?

We are currently considering purchasing a Quad 4c. Any recomendations or discouragements for this machine? All comments will be greatly appreciated.

From personal experience with 4c's: run away as fast and as far away from them as you can. These will bring you nothing but grief.

I have run the 4Cs for over 8 years it has been a good little machine. We use it for placing 10 mil pitch flip chips. I buy the yearly insurance through Tyco every year.

Hi, CP3 will have trouble placing 0603 parts - I wouldn`t use a CP3 for these parts - A CP4 will be more suitable. A older CP4 feeder will fit and function on a CP3.

Please your comments for placing 0402 on CP4? Which are the difficulties to expect and how to threat them? How to adapt the feeders for the smaller interdistance of the tape?? Thanks
