For now, on this first board, we will be reworking components such as 0805 and 1210 size caps and resistors, along with SOT-23 and SC-70 size packages. We might eventually get into BGAs. This board will most likely be a double-sided board, probably

Hi all, I just discovered this forum and I'm very impressed. We have a vendor who recently stopped placing desiccants in the vacuum packaging for our pcbs. (Yes, it's on the dwg!) His reasoning was that the desiccants can degrade the finish on the

I been a bunch o' places...! Some good, some bad, re-inventing the wheel in many cases. Our specs are pretty specific in a lot of cases, but that doesn't mean they always get followed. It usually becomes a case of "It's not quite right, but we rea

Hi, I have used both MYDATA TP9, MY9 and more recently MY12. MYDATA machines are just not accurate, and we did everything possible, and every kind of upgrade they had. We ended up putting in Fuji XP based machines, and the differences are very notic

Well put, Evtimov! :) I've made my argument against it. I'm not comfortable taking a job placing parts outside the capabilities of the machine in general, much less parts that I can't actually see! The machine is good down to .5mm pitch parts, and
