Thank you for your responses Davef and Boardhouse. The material used is Iteq Corporation IT-180. I performed more testing yesterday and found the following: I could insert Berg Pins into the assembly at various locations or a Pem. None of these

The issue is not with the stencil cleaner, it is with the construction of the fiducial. Ultrasonics is very effective in cleaning and penetrating into small microscopic cracks and crevices (this is one reason why ultrasonic stencil cleaners are so

If he is the same Martin Gershenson who works for Christopher, then I'de believe he's being sneaky. We demoed one of their units three years ago, along with Mirtech and YesTech. Of the three, they were the only ones who wouldn't let us experiment w

The Z-axis Drive card on our MPM UP2000 HiE fried. We replaced it with a new card, setting all the jumpers to match the old card. After that we had to recalibrate the Z-axis and the snugger height but the problem is that the camera is now too close t

One diagnostic tool that I have found useful in the past is the "hot plate test". Place suspect components and/or PCB's on a hot plate and turn it on High. Then observe. Granted the conditions on the hot plate are not the same as in a reflow oven,

OK Eric, is difficult answer at distance without examine the PCB..., anyway in my opinion the problem is the PCB quality. There are two possibility : the crack is between solder and nickel or is between nickel and pad copper. In both situation the

OK Eric, maybe you're right. My suggestion is to proceed by exclusion. First perform the tape test. Is easy and without costs. You have used many similar PCB without problem, but from the same vendor ? Is my experience that in similar cases the qua

Hi all, Our IPII just developed yet another issue. The PCB goes in the conveyor and when in the loader, the lifter goes up and after a few seconds I get a lifter cycle alarm error. I checked the in/out screen and when I make the lifter go up, the se

We are seeing similar issues. We have a board that consistently has failures on a BGA part. After SEM/EDS it was shown that the fractures were occurring between the Ni-P and Ni-Sn intermetallic in the ENIG finish. The element map showed elevated conc

We've been having random transducer errors on our TP recently. After speaking with MyData tech support, we were told the answer could be: 1. the transducer(s), 2. something causing undue friction, 3. something undiagonsed yet. Their recomendation
