Trying to show documentation/expert opinion to an operator or 2 why it's important to not let a first piece, that they so diligently built for the next shift to let sit for an hour, why that's not a good idea...other than me telling them so. And tel

I'm told that the Contact Systems machines we have will are set up so that if you put a sticker over the fiducial it will skip that board on the panel. I think the machine might prompt the operator that it can't find the fiducial and the operator te

We have used small hi temp labes, that are placed on our panels, boards before reflow. Each operator has a roll of labels with an assigned number. 4 operators, label 1, 2, 3 and 4. It worked well for us.

While separating individual pcbs from a panel, operators have caused delamination of the edge of the board, at the tabs that were cut. How can these boards be repaired? The delamination causes them to fail J-STD-001C 9.2.1.1.d. Also, what would yo

Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially

If you could measure and chart 3 variables in my process, what would they be? The boards that I produce are on panels that are 12up and 2x4 up. All boards are single sided paper base w/o plated thru holes. They are on scored panels that measure 7"

Grandpa, You got it - Identifying the bottleneck operation is the key. The secret is to design a tool can predict accurately where this bottleneck is. In your formula you can use machine process time, PCB transportation time, part trim time, part in
