    No; It means they just do random sampling there in the factory like all other brands do. The guy doing that sampling may or may not be Japanese but the end result is the same.
    The product quality is dictated by the contractor; thus the same factory can produce quality products or junk products. It doesn't bother them what comes out.

    Instead of repeating that over and over, show me crap caps from NCC, Rubycon, Panasonic, Suncon or Nichicon.

    There have been plenty of documented "dud" products in the past. NCC & Nichicon both had bad batches of capacitors which took down a good number of monitors & towers in the mid-2000s.

    Likewise, those brands also sell capacitors in a large range of heat tolerances, capacitance, etc. Just because the can says NCC, Rubycon, etc does not make it automatically better than another brand.

    I've had a whole ton of 3300uf 6.3v nichicons fail before. No images but probably enough for you to google

    Something similar to this: http://i59.tinypic.com/2igoewy.jpg

    Chemi-Con KZG/TMV/TMZ, that was electrolyte failure. Plus it was rated for 1000 hours and likely it actually delivered those thousand hours. But OFC I agree that is much less than expected so I replace all these on sight.

    Nichicon HM and HN, 2001-2004(5), that was manufacturing problem.

    Both cases have nothing in common with what you said. So answer my question. Or, rather, admit you cannot, because that statement was BS. Quality manufacturers will never knowingly make a cheap crappy batch because that would ruin their reputability, which means they will get finished.

    If anything, they would offer crap from some cheap fab they have stake in, but which does not carry their name. Taicon, Sam Young etc.

    btw generally speaking what can cause a series of solid caps to explode? (on several mobos)

    Closed MOSFET failure, giving the cap (assume rated for 6.3v) 12v.

    @Behemot, still crappy enough for me, bad batch or not.

    Excessive stress. There are pictures of some blown Apaq polymers under nitrogen overclocking.

    it's those Apaq solids I been thinking about since they're also on my 2ndhand board :/

    so basically what happened to him :

    could've also happened if those were jap solids??

    (problem is he says it happened with that brand on more then 1 board that's the weird coincidence that raises red flag)
