That PM460 is quite old. It would be not be the least bit surprising if either of those controller boards in the PC were not functioning. They are what 15+ years old? I would contact the US service dept. 919-460-0111, and ask to speak with Rick.

Maybe. While it doesn't help with your current problem, there is nothing that says that you cannot impose requirements in your purchase order that are stricter than D-300.

We've got a problem with a fine pitch board that has about .005" registration error at each end (towards the center of the board) when it's printed. Apparently we've got a case of board stretch generated at the fab shop. I still have to do some mea

Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.

Check the nozzle. If these are the only two parts on the board that use a specific nozzle, it's a good place to start. The nozzle is probably not releasing well and shifting the component when trying to retract after placement...

Are your pads on the board aligned correctly? I've seen this a lot lately. Pads on opposite sides are not aligned correctly. This causes the part to twist. If you have the Gerber and a way to check it, it's worth the 3 minutes to check.

Some people involved in PCB assembly process claim that SMD components reflow soldering problems are often caused by traces running under a component. According to this claim, trace (or any copper) covered by solder mask and placed under SMD componen

We use SnPb paste and bar with leaded and non-leaded component finishes. The predominant finish on components we use is Tin, there are a few NiPdAu. We've had no problems with the component finishes used in the SnPb process.
