Don't try the mecha check yet unless you know how. have you checked the coupling shaft of Y-axis? If it's ok, take a look at the ball screw if it looks like being scratched or something unusual. Also, observe the movement of the machine if you hear a

#1Run a Fuji gold board and see if the problem persist. Is your board clamp slipping? Fid camera tight? etc.. To see if you have a Y axis positioning problem: 1.Put the machine in mecha check 2.Go into Y-axis 3.Place a dial indicator so that the st

This type of component packages works best with vision type: 254 - irregular. Measure the total package length including the leads. Also set the body dimension x-y tolerances to at least 0.35mm and the the pick up x-y tolerences to 0.5mm in the part

Thanks Mika. I will have opportunity to check it out in New Year, because now we dont have production. So far we have beeen using vision type 11 and to be honest this type of defect, that placement of TNTA at flank side, happend very seldom. Usually
