Hi, In the CP6 propers, there are values: PCB Check Position X, & PCB Check Position Y. These are the servo counts that the X/Y table moves to when checking if a PCB exists on the table. Your sensor does not detect a PCB, probably because when checki

Thanks for the clarification, I have worked with both application, especially pre reflow. The data you should consider collecting pre reflow is missing, skew degrees, x,y shift, bill boarding, polarity and match the failure data (ref. desg.) to feed

Hi, I have had similar issues. First as the above replies suggest pcb fids are better than panel scrap fids, even if you have to use fids under QFP's just palce those parts last. If your machine has board skip. Place 1-2 QFP's on pcb # 1 and check

Dear Herb Intoduce a decent light source (halogen desk lamp or similar)when aligning. Then concentrate on the refection as you adjust in the x & y rather than trying to see edges of pads as they pass the appetures. Start with rapid sweeps to get

Well, the precision glass is for upward looking camera's. It essentially is a "perfect part". Vapor deposition lithography on glass (for Cte stability)....basically the part pattern (or part fids) is compared to its target location (same pattern on

Surely the next stage would be to anchor the head & pick & place at the same time cutting out the time lost in movement, then add rotating nozzle windmills to speed up nozzle selection.... I'm just remembering all the nasty things reps said in the p

There is quite some difference with a fixed head versus a head mounted to a X/Y gantry. If the head can move, feeder tables and board are fixed. If the head is fixed, feeder tables and board have to move. Spinning a component around on a vacuum nozz

Have you eliminated the hardware N.G.? Check the connection for the rear door. If the connection are ok, try to bypass the key. short the two wires for the rear door. If the rear door problem is corrected, check the rear door switch physically. Reg
