X5R dielectric aging

Electronics Forum | Mon Jun 01 22:56:39 EDT 2009 | davef

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

X5R dielectric aging

Electronics Forum | Fri May 29 15:03:46 EDT 2009 | rway

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

Where to find steam aging equipment?

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

delamination test

50% chance his boss has heard of (or maybe even one time seen) delamination and wants to be sure they don't have that problem. His boss probably felt a need to specify a test and that was one he had heard of. Personally I would recomend find a way f

PCB Test Board-stress test

First, we know of no conformal coating that will help your situation. Second, as you say, companies recognize that stress testing of shippable products is NOT good practice, because it strips life from the product. So, your product is more expensiv

Please try to use the steam aging tester and make a try ! When the water temp up to +100℃, Put your new model into the water tank. This +100℃ hot and steam water may remove the paste in via hole. Thank you. https://www.wewontech.com/steam-aging-

To be more specific. I am actually talking about the electrical fatigue whereby a unit is undergo a cyclic electric test. Unlike thermal fatigue, it is all talking about temperature related testing, eg, ageing test, thermal cycle test, etc. Anyone of

Steam Aging of ENIG

Electronics Forum | Wed Dec 15 10:48:23 EST 2004 | gopinath A

I heard that Steam Aging (storage) tests would be inappropriate for gold finishes. Is this a correct statement? If so, what are the reasons? How bad is the shelf life of ENIG

Solder Shelf Life

Electronics Forum | Thu Mar 22 03:26:42 EST 2001 | moseschee

Hi Dave, Thank you for your reply.It means a lot to me. By the way, is it possible to have the analysed data on the study you mentioned regarding the solderability "conditioning " ? Can we establish the correlation of solder shelf life based on y

Help-Wire Bonding Defects Analysis After Encapsulation

Electronics Forum | Thu Nov 26 03:59:50 EST 1998 | Chi-Ting Chen

I have some 1.25 mils Al wire bonding chip on board process. After epxoy-based encapsulation, I do some aging test. How can I "see" or prove that there is a "wire break" exist due to the tension of thermal cycling? How can I know the failure is cause
