Thanks for the input Pete. I am using CP4 8x2 feeders. I have tried first with 0.7mm nozzle. Although pick up was OK, the camera saw a pregnant 0402 part which is as you know is 1mm by 0.5mm. I then moved to specially made 0.6mm nozzle to minimise th

We have a 4C and it places 0402 components without any problems. The tricky part is getting the machine to pick them up out of the feeder it takes patience but you will get it. jake p.s. you

Hello! We placed quite a few of 0402 with our CP3 using 0.7mm nozzle with the same feeder as you had. Pick up can be adjust and calibrated, but that is not the problem, I agreed with you on that part. The trick is you have adjust and play around wi

First clean and de-bur the hole in the nozzle, then try it again. If the Head does not pick up at the feeder, then moves to the dump position...it means that the Vacuum Sensor Board has detected that the nozzle vacuum is above the LOW threshold setti

Hi All, Need your advice / help. We have assembleon pick-and-place machines and we got some pick-up issues on certain LED's that are Dome Type. The LED's get off from the tape pocket during feeding due to the dome of the LED sticks on the tape surfa

This problem has become a real issue with the tacky silicon used in many LEDs. Cree has recomended that the pull off angle be changed for the cover film as mentioned by the previous commentor. With these new silicon LEDs they are recomending teflon o

On an Essemtec machine I solved my sticky tape problem by routing the cover tape different than normal so that it pulls back more instead of up. I'm not familiar with your feeders and don't know if that is even a possibility.

It could be a part height issue. I have seen a case where an 0402 resistor from 2 different manufactures had different heights. If the height of your 2010 part is taller than you have programmed in the package data, the pick up head may be pushing

Yes, this is a good point and really only time will tell just how reliable such a machine becomes. What I'm aiming for is to simplify and reduce the number of sub-assemblies. For example we are building the camera/vision processor and lighting into

Hi everyone ! I started to program quad 4C for the first time and have some problems. First, board detection LED and proximity Led (on the front panel) are not lightning whatever I do! Second problem is I teach machine board size, nozzle locations
