You answered your own question you get what you pay for. $3500 dollar’s for a small oven is not unreasonable. I have seen small proto type ovens do a pretty good job on basic circuits. If you are getting into high density BGa stuff and multi layered

Ok Guys I need help in justification of Converting TH boards to SMT. We do quite a bit of I/O controllers using sockets and chips, and our biggest defect issues are bad chips. I am preaching to convert these boards over to SMT, however my designers

Hi Don, record the time from when board one has exited to when board two gets to the same point (this is your total cycle time including transferring in/out, fiducial checks etc). You can then multiply this out per hour. I would suggest you want to t

My company will be purchasing an AOI machine within the next 3-6 months and we are debating between several manufacturers and between "Golden Board" & "Algorithm" based systems. I've had some experience with YES Tech and have seen a couple of each k
