Hi all, How can I convince my equipment purchasing supervisors that to properly solder BGA's a 7 zone oven would be far superior than a four zone? We currently own a 4 zone oven and I'm fearful that the BGA will not get adequate heat for solder

Wow, Chunks, condescension becomes you. Not. I think that in this forum when someone mentions *stencil* printing and doesn't specify what material, we tend to gravitate towards a scenario that involves printing solder paste first, then adhesive. If

The loaders/carriers work well on CP643's in my opinion. We have had ours for about 4 years. However, if you crash them it can be a beeoch to get everything back into proper function. We have very little issue as long as we have our techs do rail wi

We have carriers that we use in wave flow solderers that are machined specifically for each board out of ESD composite. I was wondering if anyone knows about lead contamination of this material and the cleaning of composite? I know that it is a p

I agree with Sr. and Doug. Capable equipment will run like sh^t if the process is not in control. Number one, don't be scard of BGAs. They are pretty easy if done in control and will cause you less pain than you ever thought. X-Ray is your best i

Since the implementation of the ROHS process in our Company with the higher temp requirements, we had observed an increase in problems related to delamination in the PCB's. Actually we are using FR408 and Gracescore materials and are changing to a Ve

Don't do it.!!!! Are you nucking futs? Why is pre-bake required? Are you producing in high humidity? Is the package of the device poroues enough to suck in moisture? Think, consider you will not get an even "bake", the outside of the reel will get
