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 seem to pretty far from shore to begin thinking about boats and floatation devices. Most laser trimmers are used by: * Semiconductor fabricators * Resistive component fabricators * Hybrid circuit assemblers Component fabricators and hybrid [

Dear Dave and Mike, I do not normally respond to threads of the forum. However, I do enjoy reading other's comments. There is a lot of valuable information provided by both suppliers and users. You seem to be making light of Bill Schreiber's com

Are your voids looking like blow holes also? Is this only occurring on the solder joints of the Thru Hole components and Via's? Or does this happen on SMD pads? My experience is that we have seen this but only with some of our older PCB's which are

Like I said it was only a rumor I heard but intrigued me enough to play around with it one day. The lambda wave worked better than the chip wave did with makes me believe it was the surface tension of the solder not melting the already soldered parts

David Fish alerted me to this dialogue, after visiting my web site. I am one of the "anal" consultants that are trying to help people "learn from things that go wrong." I don't know where to start. Perhaps by asking you not to lump all of us toget

JAX Is right. ROI. How much will it cost to subcontract your assembly for the next 3 years vs. buying your own equipment AND staffing (ie: Process Eng, Maintenance, Skilled operators, etc.). Then, ask how much will it cost you to buy new equipment

Hi Dave, I looked into the South Coast Air Quality Management District Clean Air Solvent Certification when I was having my problems with VOCs. The problem with the SCAQMD CAS Certification is that it only certifies chemicals as they are found in t

I think we've miscommunicated....I don't use that thing for measuring paste height or volume as part of the process because it's not repeatable from one operator to the next. I use it more to measure radial tape and reel parts against EIA-486, actual

We had the same problem years ago when we started using a radial inserter. The inserter would dutyfully insert and clinch the leads. The problem in our case was the component body sealing to the fab, especially on electrolytics caps with a film jac
