On an IP3, from what I remember, the BGA Part data is defined from center part moving out towards part edge. If your pick up point is a little off this problem can occur. Otherwise, Check your gain and offset settings. The machine is probably recogni

Comments are: * Peak at 245�C for 40 sec seems like a very long time. I�d expect the time at 245�C to be 10 to 15 sec. This long time at peak could dewett the pads. * Really, their 2D vision on the printer can verify solder presence? * A thin coat

Hi All, I'm new in PCBA process. Recently in my leadfree production we encountered a missing ring on some of the ring on the board after we ran hem through Wave soldering machine. The board has gone through double reflow prior to the Wave soldering.

Larry, You always seem to twist things back to your wave solder process, ya nut! Anyway, why over simplify things when you are trouble shooting a process? The K.I.S.S. process was invented by your generation so I thought you of all people would l

Ok, So, If all the servo amps on H1 remained on H1 and the amp you changed is on H2, I have to guess the shifting on H1 is unrelated to the servo prob. Is the shifting unsolderable? if it just looks bad but will reflow, it may have been occurring f

Ideally you would want factory training but with old equipment that might not be feasible. the manufacturer might not offer training for legacy products, or the cost of the training is out of budget. Your next best bet is to find a third party suppl

Specs like beam voltage, current and focal point size are important considerations for image quality and you can spend hours going down the rabbit hole learning about them. Fundamentally, what really matters is if you can get an image clear enough to
