Depends on your company's IT policies. I have seen some companies where IT will not touch a production PC since it was not a standard IT issue PC, I have also seen some companies IT department do normal backups of the machines. (personally) whoever c

Not unless it's a case of "the only difference is..." What I mean by that is more than once I've been told the only difference in a new rev is one component or one change. But the truth was that was the only reason for the change, and in fact there

I won't even guess, but I would suggest that if you don't get much help here (pretty tough question), you might try dogging somebody at IPC. They seem to have a pretty good handle on that kind of stuff. All I know for sure is that we shipped a worki

I've had experienced this issues here with our GSM's Flex heads. Try this: 1.- Clean your linear scales with alcohol and a lint free cloth. Both the X and Y. This one has fixed the majority of our errors when one of the heads just stops for no apare

Sorry that answer never really gave you the reason and ways to resolve. Reason - most composite pallets are only good up to 180C so thermal excursions at 250 or even 270c lead free kill them. Try to stay on top of cleaning as well and some pallet mat

When placing the part to be reflow try applying heat to the board from the secondary side until the primary side has a temperature of about 130 degrees celcius. Following this procedure it should minimize the heat exposure of the part being soldered.

Dear friends, I'm from Spain and, in this moment, we try to decide what AOI we need. We had in floor, in Demo, the SAKI, and it was good. But we want to test more machines, and I heard about Omron, Modus, Mirtec.....We have a litle production but so

Hmmmm, Chicago in February or southern Cal? If I'm getting on a plane anyway I'll go the extra few hours. The show was actually very good for us. We don't look at overall show attendance we look at number of quality leads (which there were many).

I believe you are describing a pin in paste process. Not sure where a stencil is involved. Depending on you machine/pump, you can do damage to it by running paste thru it. Paste is a metal and will wear out internal parts. Also, most pastes used

if you cannot spend any money I would say that you either need to add rails or try to increase the squeegee pressure to hold down the stencil while it prints those close pads. But...... Can you put PCB onto some type of carrier that would move thes
