Maybe you need to re-calibrate your mounter?

Difference in pick height from paper and embossed reel (typically) is 0.2 mm. Try to change your pick height and place height (different type of capacitors have a different height: for 100 nF 0603 and for 4.7 uF 0603 it's a big difference!). Can you

I notice that someone has set all the capacitors & resistors parts as emboss instead of paper tape. Does this make any difference to the pick and placement of the parts, By the way recently we changed from 1206 to 0603 parts, coming out of the mac

What machine? Normally part height in the parts description would dictate placement pressure. In general, paper provides a better centered pick-up but may interfere with the pick-up(paper fibers)

Is BOC, Beginning Of Cycle? If it is how boring, The real root of the problem is, some of the parts are not put on the correct place, some of the misplaced parts wobble over on the bubble of solder going through the oven, but some been so light st

OK I can take a hint when asked for a photo. I did not try to take a photo as I thought the close up image would put the picture out of focus, so this is where a bit of graphics works might help explain the problem. When I had a look at the 1206 p

I have only one incredible idea: this is example of different speed of heat transfer of neighboring pads. I saw it two times during last years, but on lead solder pastes (Sn63Pb37). The reason of this mistakes each times we found two: 1. errors duri
