It sounds like it's just failing the laser align step. Try changing the align type for the part to "2" and see if it places it. If it's failing the laser align and you have valid part dimensions I can't help much but you might consider opening up th

Those are pretty old machines at this point, are they rated for 0402 placement?

1. For laser machines, there should be setting for Z - at what level you should cut measure the part in Z axis. 2. Check all calibrations are in place and passing 3. Check resistor package setup in the software - all dimensions

Take all of the nozzles out that are being used to place these parts and look at them under a microscope closely for blockages or dings in the surface that contacts the component. Check that the nozzle travel moves up and down smoothly and freely wi

Hi, I need help with placing 0402 resistors 90% of them are picked correctly, but are not placed(thrown away) giving me error : LASER retry over. Slightly higher varistors in same package have slightly better placing rate, about 50%, but still not su

Are you using the correct nozzle for 0402? Cant remember the number OTTOMH but 501 rings a bell. somewhere I have the table, it is in the Juki service manual IIRC. This would explain placing all others okay but 0402 is not very good , Senoirtech is c

We found a PCBA performance have insertion loss at the functional test process. We did some analysis and conclude the main root cause is from the PCB performance. What is the critical parameter in PCB will cause a failure in PCBA frequency performan

I believe I had to use the back up copy of the SmartSM folder. One of the files was correpted.

We have a Quad QSV-1 pick and place machine that has performed fine for us with the exception of cylindrical glass (MELF) type diodes. The machine often fails to pick these out of the tape to the point where it is easier to hand place them. As far
