Interesting. I'd start with the "Help Desk" at the Reliability Analysis Center [http://rac.iitri.org/]. Please get back with your findings.

I�m suddenly getting a very high failure rate in a TO99 component (National LM136AH-2.5). After some investigation we found some of these parts are more than 20 years old. What I am hoping for is that someone out there can help me find some standards

We are required by AS9100 to keep expired material/chemicals off the floor. Examples include solder paste, flux, adhesives, conformal coating, etc. We have a system in place to prevent such occurrences but once in a while something is not accounted f

You might try something simple like the appointment scheduler built into Micrsoft Outlook. Set an appointment to review your material status based on the lead time, say 1 month before expiration. Review supply and demand and order accordingly. Set

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.

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

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
