Please check the following: 1.Power supply. 2.SSR control power. 3.OTP or over temp protection at the software. Maybe you set it at low so it reads over temp even at lower temp. If still not ok you may check BTU service engineers. Brian Riggs

We have a couple of Zeva/Juki PM570L's. One machine has developed a fault with the z axis motor. It is continually 'buzzing', we have checked and there is 24VAC on it. Although even on the other machine there is AC voltage on the motor. We have sw

First question - do you have a rework station? If so, are you experiencing the same type of failures there? I have successfully used no-clean on uBGA's in the past. 6 mil solder bumps, 10 mil spacing. 88 sites. Are you reusing previously soldered uB

All you can do is to revise the testing procedures and SMT checks (pick and place vision and AOI checks) with the same fault generated in-house. This is all you can do from my point of view.

You are right. That is what process engineers are for. HOWEVER, in many cases they just can not fix a problem because it either in the part, or board or paste and so on. I used ot work for a large company in QA doing lab work for production. In many

This is fine from a quality engineers point of veiw, but as you said the vendor never admits to nothing. So the company that has the problem has to resolve the problem for themselves. Generally this turns into a finger being pointed at the process

Hello, we have recently had some products returned (they were installed and operating in the field for around 2 months before they were returned). After looking at the boards it seems the vias have failed. We now have 2 pc pcbs with the same Via fa
