Moon man was guy who contributed often to smtnet. He had a lot of experience behind him. He breathed nitrogen, drank flux with an occasional shot of 111 trichloroethane, and his lunch consisted of dump bucket vision rejects. He was originally crea

Our lines have operators on all shifts capable of doing programming start-to-finish and can deal with almost any program related problem. We are high mix, low volume. Our builds are sometimes one of a kind with qauntities of 20 or 30. We empower a

Identify the machine/program variables that can change the results on a standard sample, DOE to identify the range of each variable within which you still net the correct result, then verify before startup that each variable is within the allowable r

IF you are in the UK then you are probably best to run from that particular model at a bargain price. A huge number were released onto the market when a certain handset manufacturer shut down, and they hadn't exactly been cosseted. Quite a few comp

Nothing like making a handful of changes all at once to confuse an issue, huh? Did you (or whomever ordered the stencil) spec. the same stencil design parameters that you would normally have used? We've never done fine pitch of any sort on silver

Some software versions won't allow a brightness change with the next button. You should do a histogram test. Place a board on the worknest, then a smooth white card on top of that. Then jog the camera over the card. Raise the Z-axis to it's softwa

Yeah, changing it while you run is ridiculous. I would take my thinnest part and play with the thickness, until you make it as thick as you can (and still place the part with good results). Then use that thickness for all. You can put a dial indicato

Dear Bruce, We had the same problem in the same condition. Every compnent and the PCB (OSP) has changed as lead-free and we need to solder them with SnPb. For solution we have increased the flux amount applied on PCB and the pre heat zone temper
