Sal, I have seen this problem placing SMT connectors which exceed 60mm in length. Although I did not use siemens equipment at the time I am not sure if they will place enought force to seat the entire connector flush to the board. They have a maximun

--IE, Funny.--- I "remember" kinda, from the early CP6 years, things about the springs. The early Fuji springs had sharp ends, and if you spun the nozzle, prior to final attachment, the opposite way it could stick, and if it was spun the right way,

They are actually diamond impregnated tips. The tip can be cleaned using a special jig. this will extend the life. these nozzles are from a machine platform dating back to 1997. The RSS can last for 1,000,000 cycles. SA and MA are similiar but requi

Sounds to me like your nozzle isnt seating on the z-rod bellows. Pick a nozzle up by do a 'runstep nozzle'.....then do a function 30 ( i hope thats the function because its been YEARS since i worked on a c'series). It should give you a nozzle height

When I see this on my QSP2 it is always caused by the nozzle not seating ideally but I tend to set my tolerances really tight. To test mount a nozzle and look at Z height. Now pick up the part (which in my case will suck the nozzle upward due to the

My favorite kind of calibration is where the machine learns what it did incorrectly. Then fixes itself! However, there are many types of machines that rely on human feedback as to the results of what it did. nozzle calibrations involve many factors

Here are a couple of things to look at. 1. Watch the machine run....and if it misses a part....make sure it doesnt blow out the next part being presented. Sometimes the air pressure is too high and the vacuum verify will blow the part out of the poc
