Call Ken Gribble at (408) 383-0704. He is the SRT Rep. for the San Jose, CA area. I just purchased an SRT from him about 6 months ago. SRT is top of the line. I haven't heard of the model you referenced. You want to make sure that your not gettin

Chryzs, I've used AIRVAC and SRT (with their old adjustable 4 piece nozzle system). I also saw the APE Chipmaster... Here's my 2C after all that: Whoever claims he/she has a user friendly system is a big liar. The words are correct but the order is

We have seen this problem several times. It always goes back to pad solderability, very seldom does it have anything to do with ball size. If there is no evidence of wetting on that pad, but all of the other pads did solder, you need to ask yourself

Dear Dreamsniper, A big hidden cost in any cleaning system is the cost of diminished production and rework. I assume you are cleaning the adhesive stencils manually since there is no equipment cost in your formula. Manual cleaning of adhesive sten

I work for a contract manufacture of PCB's, we are also in the BGA rework business. We see all kinds of different size boards, as well as different types of BGA's and micro BGA's. We selected the Conceptronics Freedom 2000 over the Air Vac and SRT. T

Chris: Whatever way you decide to define your pads, use the same type on the component and the board. Non-solder mask defined pad advantages: � No point-of-stress concentration at edge mask and solder ball � No CTE mismatch at edge mask and solder

The solder ball collapse is associated with overheating. Of coarse there's no problem taking it off, your nuking it. The problem, as your aware, is in the replacement. The machine your using is overdriving the process. The key to this repair is in

You're not sposed to pull the mask from the BGA when reworking it!!!! ;-) Well, if you insist. You can be as fancy as you want. Basically, all you need to do form a dam to prevent the solder from flowing from the pad to the via and starving the
