If there are too many components on the board and many components are standing near the board edge,to use a depaneling machine is a simple way,but a machine is needed, another possible way is to design and make a simple fixture,it holds the board fi

Probably to late for ya, but: -Center support -mesh belt and conveyor (have the mesh is nice for 1st side runs to keep the board flat. -N2 capable, in case you need it -on board profiling -smema if needed -board drop detect (sensor at input and exit)

That's what I said when we started talking about 48inch boards. Everything changes. New printer, bigger stencils, new pick & place. Different even profiling (the board is in 3 zones at the same time). Plus board racks don't work well. The old Boa

Thank you guys. And Yes, the process and knowhow of the team has a lot to be worked on, but Work Orders are of 5k to 10k units, so miss-printings will occur everytime that the printer is setup at the very least. I wonder if you have a PCB washer to

Hi Gurus, Looking for alternatives to line makeup after reflow oven. Currently, I have a continuous on flat belt conveying out of my reflow oven straight to an EOL bench. The operator manually picks up the board off the belt (there is a roller at t

That's a rev 1 board, my machine has a rev 2. I have no idea if they are interchangeable. So, I bought a Rev 2 board from Korea. But, I'm flying pretty blind on this. I have traced the ready button signal to a microprocessor pin on the IO_DPRAM bo

Welcome. First, proper alignment can produce an order-of-magnitude increase in the number of boards that can be printed without wiping. The initial alignment can be made either by: * Peering through the stencil apertures at the board underneath and

Can anyone point me to a relevant IPC spec that specifies an allowable board stretch, measured between metal features on outer layers (e.g., between fiducials and component pads on the topside of a board)? I've got a non-linear stretch problem that'
