Why are crap caps still in use???
Who knows??? No way would I consider cost cutting a good reason. Planned obsolescence??? Incompetence??? Anything else???

Re: Why are crap caps still in use???
Cost cutting is a damn good reason... 3-5 capacitors per monitor, 100k monitors equals 500k capacitors. The difference between 0.30$ per capacitor or 0.10$ per capacitor when you buy 500k capacitors can be a lot.
Also... designs rushed to market, sometimes without evaluating properly the effect of temperature and dust on the components inside. Sometimes it's not quite so good engineers.
Incompetence... business managers and purchasing managers thinking they'll get a bonus for saving company a few cents choosing another capacitor manufacturer even though the engineer specified certain series of capacitors...
Sometimes it's also pride...like Samsung sticking with Korean manufacturers of capacitors (Samwha) or Chinese companies NOT working with Taiwanese brands...
Sometimes it's intentional... make the chances of failure after 3-4 years high and give them 2 year warranty, so that they'll pay 50-100$ for warranty or buy new set.. -

In the short term yes, but you don't save anything in the long term if the result is EPIC FAILURE.
They'd know the consequences if they'd just take the time to read these forums...Also... designs rushed to market, sometimes without evaluating properly the effect of temperature and dust on the components inside. Sometimes it's not quite so good engineers.
In my mind I'm thinking of starting a top-quality PC company. To find employees that have any real competence at all would be hard enough, let alone employees that know how to build top quality. Maybe just going on by myself would be easier.Incompetence... business managers and purchasing managers thinking they'll get a bonus for saving company a few cents choosing another capacitor manufacturer even though the engineer specified certain series of capacitors...
Local isn't always the way to go...LOLSometimes it's also pride...like Samsung sticking with Korean manufacturers of capacitors (Samwha) or Chinese companies NOT working with Taiwanese brands...
Oh no!!! The environment!!!!!Sometimes it's intentional... make the chances of failure after 3-4 years high and give them 2 year warranty, so that they'll pay 50-100$ for warranty or buy new set..

Re: Why are crap caps still in use???
I think another reason for using bad caps is because manufacturers have no idea that the caps they are using are in fact low quality. For example, few people outside of badcaps.net realise that KZG are bad. Even many reviewers think Teapo are also good. From my experience, they aren't much better than Fuhjyyu.I love putting bad caps and flat batteries in fire and watching them explode!!

Re: Why are crap caps still in use???
You know, there were manufacturers that cared about capacitor quality before the Bad Caps scandal.
I think this case is somewhat forgivable because (A) they know it's from Chemi-con, so they think it's good and (B) some people might not even understand the different series.For example, few people outside of badcaps.net realise that KZG are bad.
I can't really forgive people for this because since when was Teapo Japanese???Even many reviewers think Teapo are also good. From my experience, they aren't much better than Fuhjyyu.
In order from best to worst, how would you put the different non-Japanese brands??? I'm leaning on Taicon as the best (excluding SamXon). There could be brands worse than GSC/Evercon/Sacon, I suppose - not that you're likely to encounter one. I'm also curious about Aishi. I've only seen about 1-2 blown myself (in CFLs), but they aren't common so this isn't saying much. Any experience with them???Comment

Re: Why are crap caps still in use???
Well, in my bag of bad caps I pulled I have approx %:
40% CapXon
30% Samwha (90% WB, 10% XC)
15% Teapo
5% Samyoung
5% "Other Chinese Brand" (JH, TK, Jackcon, Jun Fu, others...)
5% Chemicon (KZG)

I don't know their current practice, but the Deciduous Fruit Computer Company in Cupertino used to (ca. 1999) specify that only Nichicon and NCC/UCC 'lytics were to be used in power supplies for their products.You know, there were manufacturers that cared about capacitor quality before the Bad Caps scandal.PeteS in CA

Re: Why are crap caps still in use???
Yes you would. The low quality caps are your fault. Here's why.
Add $5 for good caps at manufacturing.
Add $10 for good caps at source distribution.
Add $20 for good caps at destination distribution.
Add $40 to the price of a TV set at the store and it won't sell. This other brand is the same TV for $40 less and I think it looks better.
As for planned obsolescence, look at the rewards for cutting $5 at manufacturing. Lots more TV's sell, the boss gets a new Ferrari, and the workers get to keep their jobs as the customer pays for the same thing again and again. Corporations win and people lose. It's win win for everyone!
Did I forget to mention it's YOUR FAULT (and mine), you cheapskate?
TV's have it even worse. People are begging for reasons to be "forced" to buy a new TV. Breaking down is like a message from heaven: $PEND!Comment

Definition of planned obsolescence:
NO company in the WORLD has ANY right to do THAT. Period.Severely frustrating the customer while using up valuable resources and creating lots of pollution. All that just to get a few more $$$.
Don't even get me started on computer speaker power ratings.Comment

Re: Why are crap caps still in use???
Before the advent of LCDs and plasma, CRTs were essentially the only technology available. And people liked that. Why upgrade? The only big change in CRT technology was the introduction of colour, but that was it for 50 years. Same resolution. Maybe SCART was a new feature.
Now, with LCDs and plasma TVs, it is display resolution, contrast ratio, motion-enhancing nonsense, new incompatible inputs, whether it's 2D or 3D, LED backlight/new PDP/etc... manufacturers have to keep coming out with new stuff (and make the old stuff break) to convince people to buy a new thing, or everything will stagnate again.
Things -must- break or people won't buy something new. Or, they will, but they will then sell their old equipment. That's why many retailers give incentives for old equipment: to remove it from the used market. It will simply be disposed of. One less used thing to compete against. Game publishers hate used games, worse than piracy for them.
Solution? Maybe: Encourage companies to offer a warranty on all products. Say, a 5% VAT cut for a 5 year warranty. 10% for 10 years. Perhaps a minimum of 3 years. Also, instead of making it the retailer's job to dispose of the TV (WEEE), make it the manufacturer's responsibility -and- if possible introduce an incentive for refurbishing over disposal.Please do not PM me with questions!

The tech industry is seriously going downhill...
What's the best way to get true quality???Comment

Re: Why are crap caps still in use???
Study lots of reviews for hardware, see what company is consistent when it comes to the quality of their products, then choose the best price for the value.
For example, I could buy an 1300$ Eizo LCD screen that will last 10 years or more, or I could buy a 300$ Samsung LCD that will last 2 years and then buy another 300$ Samsung LCD that's more advanced than the old one, and repeat the process.
If I hate the waste, I go for the expensive Eizo.
But I guess I'll get more value for the money by just buying another monitor when the old one starts to go bad. Spending just 300-400$, I can invest the rest of the money or leave in the bank to grow.
As good as the 1300$ Eizo could be, it's inevitable the CFL lamps or the LEDs inside will start to go bad after a few years...
On the other hand, it can be very different with other hardware, power supplies for example.
I spent close to 250$ on my Seasonic X-650 when I could have spent 100$ on a decent normal one.
It's on one hand a sort of insurance for my system so I know it's unlikely to die and kill other components in the system (the Seasonic is top grade psu, all quality parts inside, Japanese capacitors and all that).
I also know that unlike cheaper power supplies, this one will probably last me at least 5-10 years.
And last, due to its increase efficiency (up to 92% efficiency), in long term especially as my system runs almost 24/7, I will save money compared to using the cheaper 100% psu with 80% efficiency. I'm probably saving 5-10$ a month in electricity costs - the difference pays itself in a few years.
So with monitors, it often doesn't pay to go for a more quality, expensive one, while with other components like power supplies it does pay.Comment

Re: Why are crap caps still in use???
as far as motherboards is concerned I'm seeing a trend going for solid vrm caps, and a number of all solid cap boards. In addition more power phases reduce strain on each individual 'fet, but I see most fets are double-packaged and not heatsinked, which concerns meCap Datasheet Depot: http://www.paullinebarger.net/DS/

Hello!
I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.
The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.
I have studied the board and... -
I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,... -
Good evening
I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?
But I was also suprised about the bigger boys, which are 330µF 25V.
Could it be they used 25V caps because they were cheaper / available at that time?... -
I did it again – I had to fulfill my inner desire to fix yet another old piece of hardware. This one is actually kind of worthwhile, too – it’s an EVGA e-GeForce 7600 GS AGP video card, model P/N: 256-A8-N542-T2. With the popularity of “retro” PCs from the Win9x to XP era going up, and the diminishing supply of decent AGP cards, it is expected their prices will go up. Or is it? I bought the this video card rather on the cheap side (~$9 USD shipped to my door), because the eBay seller listed it for parts or repair (and correctly noted the bad capacitors.)
So, here is the...
