My experience has been that one is a near impossible number for a professional organization. Their tools and process just doesn't scale to that point. Presently I've tooled up in house to handle the one-offs (and I have managed to avoid BGA) At one point in the past, I had a good enough relationship with some of the people in a local assembly house that I could bring something "in the back door". Show up with a board, a part and a case of their favorite beverage (Mountain Dew in their case) and I could get a few minutes of time with their rework guys and their really nice hot air guns. -Denny On Wed, Feb 8, 2017 at 3:06 PM, Neil wrote: > What do you guys (in the U.S.) do about one-off prototypes which you > can't make in-house?
