1 x 10^10 ohm. Can i use the same specs? 2) Similarly, do anyone have a guide of the pass/fail criterion for the DWV measurement for parylene on IPC-B-25A board? I had check the Mil-I-46058 test standard which had a pass/fail criterion of

What exactly are you looking to verify? Following the manufactures recommended schedule for calibration should be enough. Another option is many AOIs have an option to run a bare board, when doing this it will invert what it's looking for, so every

AN inductor probably 22uH 5A. Check a TDK catalogue http://en.tdk.eu/inductors Another approach is identify the power control IC next to it and look up the App note associated with it, 9 times out of 10 it will be the same as recommended. Are you s

Hi Muzzy, We are experiencing a similar issue with our Juki KE750, the machine did not perform zero rutine, some of the ALM4 led in the zeta ant theta drivers are turned on, and the SUB-CPU led "FAIL" is also on, did you mean that when your machine

That's a good point, although hand soldering a xfmr on a RoHS assembly isn't going to be a walk in the park. My other question would be did it fail because it got hot, or did it get hot because it failed?

We acquired the machine few weeks ago and it was working fine until the printer won't initialize anymore with "USC park failed" error. It seems that the printer won't respond to "4 MAXY_SP 61,0" message. Is someone has already en

We are having a small number (~2%) of our boards pass our manufacturing diagnostics, fail once they reach the customer, fail when they get back to us and then start working again after handling them for a short time. We have eliminated a lot of item

We have an Ionograph 500 M SMD II tester. A couple of months ago, it began failing bare boards at a very high rate. We use 10ug/in2 as our standard. Typically we would fail, maybe one board every 6 months. In the past two months, at least 15 boar

Hi, when they did the reflow with the south bridge chipset they took a heat gun and went arround the chip in circles. This is what I did with the broken apple motherboard. I covered the board in tinfoil and cut out the squares arround the gpu, cpu an
