Is there anything stopping you from replacing the flat belt solution to a continuous running steel roller chain conveyor? - From there (depending upon board temperature) you should be able to buffer your boards in a vertical buffer station if neede

The tightest spacing between neighboring 0201 components assembled was 8-mils. Please refer to the response for the query entitled �Minimizing Tombstoning Defects� posted by martys, as the response provided there is also relevant to address this que

A simple trick I read either here or on another P&P forum is to use "Silly Putty". Place a small thin spot of Silly Putty on the top of the front conveyor rail, and put the machine in "manual" mode. Steer head #1 over the putty and lower it, leavin

Thank you, that works perfect!! Now I was able to set up the offset's and program the machine, but now head #1 will move to the feeder location but it will not move down to pick up the part, then it moves to the drop area, but its only happening on h

Does nozzle #1 lower at all when it should pick up a part or is it just staying in the fully up position? If it does come down, but not quite far enough to contact the part, there are adjusting nuts on top of the head that set the lower limit for no

Hello, I have a CSM-84 pick and place machine, and every time a make a programm the location where the part get place is way different from the location on the program which tell me that the offset's are way off, but when I try to calibrate the mach

Thank you for your fast reply, head 1 moves to the pick up location and stays up, then it moves to the dump location and moves down to drop the part, it was running before just the offsets where off (moving up and down). If I chance the head from hea

I've never seen a good article with a definitive explanation - just speculation that the increased wetting forces due to nitrogen result in increased tombstones. My own experience is that nitrogen is a very minor contributor to tombstones and can pr
