What do your people working on the lines have to say about it?

hum, I see no problem for your people supporting any line that can run this speed. If your chip shooters are the dual feeder carriage kind, you must run them in replace mode, when one feeder runs out in one carriage, it parks it and continues running

20in/min you have plenty of capacity.

well, my concern is not the equipment, I know we could have the lines to do that, at this time not the required space, but what about the people? I mean, the machines are not 100% human beings independent, will the people support feeding, wiping, ins

Believe me, I don't see any problem about optimization on Placement equipment nor printing or even the oven, my concerns are with the people: - Am I on the limit to assemble about 1100 to 1200 boards per shift (8 hours)? I have seen some of our lines

Hi I aa QE on SMT line that produce products for Home introduction. No so long ago we have a problem with soldering of BGA Head on Pillow (root cause mismatching customer requirements and BGA profile spec, suplier change %Ag) and our product affect

Thank you for advice, But main concern how to detect the problems with BGA on SMT line, and how I can validate "good" or "bad" profile. PS: SPC said that process Cpk 2, temperature profile in the upper spec limit for TAL and peak temperature.

Hi to all, I have one question that I hope to receive comments - Does anyone know or have any experience for the maximum boards you can run on a SMT line, this is quite general, but let's consider a board 8" x 8", about 400 components. Regardless of

Hi Ricardo, You should complete the question with more details like : - kind of components pkgs (Chips, SO,TSOP,QFP,BGA,CSP,etc) and % of them versus the total (400) - tech complexity of components (0402 ? Finest Lead and ball Pitch ? SMT conne

ricardof Unfortunately I cannot comment on many of your questions however I can lead you to one important article as to basic assembly optimization techniques to maximise throughput (or minimize assembly time, which is pretty much the same thing...)
