Hello Joe, PCB size 6" *6" is larger board. Resistors and LEDs are easy to do assembly. I think you can ask Beijing Glichn, from PCB stencil printer, SMT reflow oven and LED pick and place machine, they can give some suggestion. The investment is de

Hello; Can anyone give me advise on the best way to manually align a 20"x20" stencil on a semi-automatic printer? We have a board with a 16 mil pitch QFP and have difficulty aligning the stencil. We have tried various alignment schemes on the pcb an

The vision on our semi-automatic printers allows the operator to draw a box around a pad for reference. Then as long as both reference pads are lined up on consecutive boards, it's aligned.

If you are running FR4 PCBs and not something exotic like Kapton flex circuits, I would go with the Dek 265 any day of the week. You will find that Dek supports the fully automatic printer much better than the semiautomatic printers like the 260, 24
