What kinds of equipment are you looking for? Alot of people arent explicit these days, guess it's the holidays. Had some rabel-rouser borrow my volt ohm meter and the next thing I know it's on the line being used as test equipment. Tried to give a

Hello All, One of our operators recently placed a PCB inside our reflow and when the PCB came out, the board was dark green! My question is, what would determine if this board is acceptable or not? I tried searching it, but couldn't find a re

I would take the board in question and run it through again with your profiler to verify that no one has messed with your oven recipe, or your oven isn't malfunctioning. Also, a before and after pic attached to the post would probably be helpful to a

Hi If you mean your PCB stayed in the Reflow oven more than the reflow time required for the solder paste specs then I suggest to throw away the board because it would lead over heated solder joints all over the board. Think what could happen to an

Solder mask requirements: * IPC-6012 and IPC-SM-840 contain detailed specifications and information regarding solder mask requirements. * IPC-A-600 defines acceptability of printed boards [analog of A-610 for board assemblies]. Why can't you use A-6

One of our instruments has a high impedance front-end. We: * Passed functional test in the environmentally controlled shop. * Failed test, on the same unit, while carrying it to burn-in chambers in an uncontrolled part of the plant. Solder flux resi

I have to make a few fixtures using durostone Material. I would like to know what end would be best to use for milling pockets out. I tried using HSS 1/4 in all I did was burn it up. Also I tried to use a 1/4 " carbide end and burnt that up too. any

Tom, V3.78 is truely a bad version and does not include GLOAD. Files taken from the machine with V3.93 can stumble, but can be read... so I would recommend burning V3.93 EEPROMs. Only do this if both machines have Vision and DC Servo Motors present.

Almost sounds like a part fell in the pot, exploded and burned into powder. We had a part get into our pot somehow and produced powder dross + other contaminates (no solder balls, though). The ring around the pot was very difficult to remove but wa

We are using Nutek NTM4910-XL laser marker to etch 2D barcode on all our boards. We added solid silkscreen box on all our boards to create contrast. When we laser etch them, we just burn the silkscreen box so that we can see the soldermask under it c
