Hello! You can check your vacuum in MANUAL and then VACUUM IN MONITOR. You can switch the vacuum on or off for each head. With a TYPE 72 nozzle and no component the vacuum should be around 80 or 90 and with a component at the nozzle it should be ove

thanks everyone! When we have a PCB to do, for one component, they usually give us an excess of 10 components! We are issued over 2,000 components. Does that sound reasonable? The problem is usually when the head picks up the component before it r

What we have had recently is a lot of larger thin (32 thou) thickness boards that have had issues with SC90 diodes bouncing off the pads in the final PNP machine. Our setup, universal instruments GC120 or quad beam 30 spindle lightning heads. This m

i worked with cp6s in 1995 and 1996. we always had missing part problems that was machine related. we had to inspect every board for missing parts. it was a disaster, imho, but i expect a chipshooter to consistently load chips. otherwise, it was
