It sounds like the vac-verify is not working. There is a command on the hht to turn it off. When turning off your hht will show either 'idle' or enter command' without the V showing anymore. Maybe try the cntrl and vacuum or shift and vacuum. If its

Make sure your placement rotation co-ordinates are correct. If you do a function 3 it will show you. I think they should be in multiples of 6000....ex...6000 = 90 deg. Also check the z axis number. I dont think its cyber or vac related. It is somet

Also, be sure that your support pins are set correctly and do not allow the board to sag or bounce. Next, is your z correct? Its possible you are pushing the part so hard into the PCB that it's pushing back up or even bouncing the board and throwin

Hi: Use the whip on your operators.!!! Serious: The assembly should know how much time they have left to process those parts safely. Keep them as long as possible in the drybags, reclose the bags immediately after getting the needed parts out. In t

C.Long, Have you thought of using a barcode reader system? Though costly, such a sytem would minimize the room for error and neglect by your operators. Yes, physical tickets would still need to be applied (barcodes labels) but there would be less ef

You could have said "why don't you just flop 'em over twice into the right tray?" lol. Yeah, that's the right way. I was kind of focused on what I had to do here to get two different parts from full trays into two cut-in-half-the-long-way trays sinc

Innovative Drying Co., considered this possibility early in our experiments. The rate of chamber pump-down is not a consideration. However, the selection of the vacuum pump is critical. Avoid oil-sealed pumps at all costs. A poorly maintained oil-tra

I would love to see the documentation of the experiment that indicated that a 24-hour/70 degree C bakeiing cycle at 10Pa is more effetive than a 24-hour 125 deg C baking cycle at normal atmosphere. We have looked at the old Levey-Perlmann paper and f
