Large-Scale Faulty Capacitors

Faulty Low-ESR Aluminum Electrolytic Capacitors

Has anyone here seen concrete examples of this "phenomenon"?

This site claims that there was a fairly large scale supply problem with Many Major manufacturers unknowingly getting defective capacitors.

Yeah, if memory serves, we had a rash of A-Bit motherboards going bad because of faulty caps.

old news.

were probaly seeing hte effects of it now as this equipment nears the life expextancey of these parts.
Havent been buying tiwanees caps for 1 1/2 years now. (or products that use them) drives sales men nuts: Prove the origin of all capacitators in this unit or I wont buy it. realy limits my component choices, but I have peace of mind that it will work for a long time and be reliable.

Lots of examples yes!!!! If I remember A-bit was the only company to admit there was a problem and offer to replace the boards.....

Not large numbers, but recently did a batch of MSI boards for a local computer store.

still dealing with them. Just got 6 ecs board in all with faulty caps. SO far I have seen it on all the boards we sell; ASUS, Abit, MSI, ECS, Gigabyte, and Tyan

I first heard of it about 2 years ago. To give you an idea of the timeline...it was when A7V133 mainboards were still being produced. We had faulty boards from Gigabyte, Asus, Abit etc.

Actually, shuttle did as well, we RMA'd about 45 of them. AV11 I believe

I just mailed a Gateway Profile4 (bought Spring of 2003) back for service that had two blown capacitors (near the CPU heatsink). First ones I'd ever seen.
I saw my first photos of this about a year ago, so I new what to look for. It was obvious: charred crust on top of each, and crust underneath one also. That latter one almost came off the motherboard.

@FireAm94 please don't scare me. I just rebuilt my ASUS A7V KT133 computer with WinXP and it's humming like never before. All I need now is for it to give up its ghost! I think I'll do a pre-emptive examination to see if anything is starting to fry.

most of the caps involved in this ( if not all ) had a "+" on the top. I don't remember ever seeing ones of other configurations have this problem.
