We have recently begun using X5R dielectric capacitors. Although they have a better temperature coefficient over Y5V, they age much faster (5-7% logarithmically per decade). I assume the reason for using the X5R was the availability of the capacita

Here's your test definitions [clipped from the dictionary in the fine SMTnet Library]: * Test, Automated. Computer controlled electrical testing of parts, assemblies, or finished products. * Test, Built-In (BIT). An electrical testing technique whi

Good Idea. I think there are many Bad apple used equipment dealers as well. We should track them as well. Every bad apple needs to be dealt with. OEM must make money to survive and support systems. But I must tell you for example I have found many th

Does the file come off of an ICT. Next question is it an AGinet/HP/Keysight 3070. If so you have a chance at finding out the format. It is probably posted online in the Keysight manual downloads section. I might still have an old paper copy of this

Is this a new assembly/new test fixture/program? Or is this an existing assembly that is suddenly exhibiting this failure? Capacitors measured in circuit will not necessarily measure their correct values. Active components in circuit will be affec

In my experience, the most commonly accepted theory is that 100% inspection is only 80% effective AT BEST. That means that if your inspoectors are happy, noy outside concerns, well-rested, etc, they will catch 80% of the defects. This number goes d

Out of interest, are you using an 84V? 84VZ? a 60V? 60VZ? With SBIP or the Yamaha vision system (VICS 1000)? Do you have the old tray sequencer? > WRONG!!!! Why do folks still live in this mindset? I'm not slamming you personally. But this is preva
