The low value will be 0.624uF. You have to factor it from the low tolerance (-10%). So: 0.9 x 0.92 (machine tolerance) x 0.91 x 0.91 x 0.91 (3 decade aging factor for X7R dielectric). We factor hours at the 3rd decade (10,000 hours), but you can

Have you verified the measurements on the bench with an LCR meter? Chances are you are experiencing aging with these ceramic caps. We have similar issues with X5R and X7R caps. You will see the effects of aging with returns from the field as well

If they're 1 1/2 years old, they are definitely aged parts. Either send them back for newer or widen your tolerances on the ICT to compensate. You are at the 3rd decade now (10,000 hours) and you will need to compensate for this. These parts are n

200 boards an hour and probably does. Our slow P&P machine keeps us from getting that benefit. But we get to have all the headaches. I think the printer runs on a 286! That's pretty sorry for such an expensive piece of equipment. The stencil frame is

Everything went smoothly. I had the motor in less than one day. And I saved $690 from Electrovert's $1170 price (slightly different model but it works great!). | Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a

The Field Operations Manager showed up yesterday because he'd heard about my smtnet ranting. Now they're going to send somebody up here to look at the six year old machine. Free. It's hard to top service like this! Companies That rule (alphabetical

Our Electrovert UPK445 needs a new solder pump motor. The Machine is down. I'm taking a huge chance with Specnor. If the motor doesn't come in or if it doesn't work, then I'm dead. They told me I'd have the motor next day. They kept trying to sell me
