Reflow soldering de-ages the capacitors. Two things may be affecting your testing. * Capacitance measurements are often erratic during testing for about 10 hours after de-aging. * Test limits should be set so that the capacitance value is within the

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

I work for a medium sized electronic manfacturing company that is looking into potentially purchasing our own piece of steam aging equipment, but I am having trouble locating manufacturers. So far I have only found H&H Engineering in Stockton, CA. D

Davd, Thats what first came to my mind when I was asked to do this task, the old train belching out climbing the last hill towards town ;) H&H Engineering has what used to be Mountain Gate's line of steam aging equipment. They are at 209-475-0693

Ah, that was the time. Those locomotives chugging down the tracks with a plume of steam and coal dust rising above and dissipating down the track towards the end of the train. "Driving that Train, High on. . ." [http://www.thespoon.com/trainhop/song

Can anyone help with advice on the possibility of "rejuvinating" aged solder paste for SMT applications. Thanks!

Honestly, I wonder the same. Is it Age the only variable to this? I can not reduce ageing.

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

Hi, I'm looking for research/study done on solder shelf life by using accelerated aging process ( steam age or dry air oven bake at 150C & etc ) Perhaps you could help to advise correlation of all this acceleration test to actual solder shelf life
