SMTneters, I'm conducting a workshop titled "Circuit board repair on the Internet" at our California facility on November 10. Similar to a recent posting, I'm seeking suggestions for online resources to discuss with the attendees. In addition to

I have two of the servo boards of the Fuji CP4-2 SMD3 version are mulfunctionaled. I don't know if it can be fixed or not. May be the moisture killed the board. A new one costs about USD 5,000 each. I wonder if anyone knows who or which company can

Fuji is usually the cheapest you will find. I think around $750 for them to repair it. the last time I checked they have an exclusive patent on their PCB backplane design so there would not be any real way to bench test it. they also have rights to t

Dave: Thanks for the info, I appreciate it. You start off by naming a +/- 2 sigma process, is that equivalant to an AQL of 0.25 ? What is a 6 sigma equivalant to? You mentioned the AQL at incoming inspection, what should that be in relationship to

I just wanted to thank all of you who responded via e-mail to me regarding this subject. After a lot of looking and talking, I decided to keep using Unicam. I'm working on adapting my use of UC to fit my process a bit better, and hopfully, more effic

Working DFM SMT issues with respect to a client's artwork together with a heavily modified solder stencil, I was able to reduce 0402 tombstoning from 80% across the board to 3%. I winged the aperture reductions, but are there any "rules" or guidelin

Larry Elaborating on the specific question, yes, the volatile solvents in the flux can and will evaporate. Evaporate completely in any reasonable amount of time? Probably not. What tends to happen is that the exposed paste dries on the surface and

The CCGA package is difficult to handle and automate in the assembly process. The leads can be fragile, and vision recognition of the package and leads is difficult. Special lighting and/or a special vision algorithm will probably be needed if you wa

Water soluble masks are great in my book. After having used the latex type, I found that the water soluble will save a lot of time. I dont't use a closed loop system, but I do have a filter on my discharge line. I have not experienced any filter c

As a stencil vendor to some assembly houses and small in-house assembly shops, both without CAD people rushing to put the paste layers (if they even generate one) into stencil friendly format, the silk screen is the only communication tool we have to
