hi, can anyone share experience on PCB open trace repair? we have some data that indicates that this repair is high risk and really very dependant on repairer skills. It may also cause reliability issue for trace repair. please advice.

hi guys the scenario is: when placing parts which required maximum speed, the cp6 sometimes missing resistors here and there, when checking part data, everything ok i notice that when the machine switching between high and low transport speed, (eg: r

Hi Better to check the table calibration and wedges also the rack and pinion gear at the back of the table for control if you go into mechacheck you can set the servo and the calibration data if its an early cp6 its quite simple to set up if its a cp

If you are sure that your part data is correct, have you checked the calibration of Z origin? Are the parts leaving an impression on the paste or is there no indication of an attempted place. How small of resistors are we talking 0402, 0603, 0805?

Hello! all Will anybody give me advice for missing componets for 0402, 0603 R or C chips? I am not gonna tell you which machine I use, but from my experience, every p&p machine has possibility for missing component after placing 400 or more componen

Thanks for the response Thomas..You are correct I got solder paste on both edge on the nozzle type 4007. But it uses for nearly 30 types of part number ..and also I will get missing without any issues in nozzle..I am unable to find the trace in that.

Should be some numbers on the top of the other two. If you can read them we can get you the right part info. it also looks as though you have some trace and pad damage that will require repair prior to you putting down new part. Or you can remove

Dennis, The solder paste is responsible for holding the component in place pre-reflow. Several things to look at: Is the paste accurately printed on the pad? If not, there may not be enough of the component in contact with the paste to provide adiq

Hi All, I would like help in establishing what is a feasible PPM reject rate from a typical SMD line. As a reference an SMD line consists of, solder paste printer, chip component placement, pick and place IC components and reflow. What is a bench

We have had this problem with one of our machine although it is not a Mydata. We had to reduce the blow off time for these. Our problem was also these same Rnet packages. the part is proabably picked a little off center, then the blow off hits the
