Power supply caps fail so often that maybe they should be socketed?

Power supply caps fail so often that maybe they should be socketed?
- bserge 5y agoWhy would they be? Less money for the manufacturer. Just throw the whole thing away (preferably in the garden waste bin for that extra good feeling) and buy a new one. /s
- kalium-xyz 5y agoNah soldering isnt that hard an operation and sockets are expensive.
- contravariant 5y agoThough it'd be nice if they made those kinds of things more easily accessible, rather than hiding it behind tons of warranty stickers and really tiny screws.
- kalium-xyz 5y agoSure, just saying that it not being socketed should not be that big a barrier to entry. If you want an awesome way of doing things look at old tektronix scopes https://w140.com/tekwiki/wiki/Ceramic_Strips https://w140.com/tekwiki/wiki/Ceramic_Strips
- BizarroLand 5y agoI'm assuming that the reason why there's so much discussion about soldering techniques and practice on that page is that the tubes failed on a predicable schedule and user servicing the machine was a mandatory part of ownership, right?
- kalium-xyz 5y agoThe tubes are socketed. Not sure if the soldering was entirely meant for the users or for specialized maintainers, might have been a mix. these things cost the price of a new car and came with similar responsibilities. The soldering techniques are to prevent bad contacts or impurities as this is sensitive measurement equipment.
- ksec 5y agoThe answer isn't socketed but high quality capacitor ( Solid or Tantalum etc ) . Swollen capacitor should really be a thing of the past. Unfortunately Capacitor is an area that is easiest to cut cost and has no immediate effect on the devices function and are hard to spot. Part of the reason why I switch over to Mac ~20 years ago. I dont want to spend time looking at every capacitor on a motherboard or to gather enough information on all these details. That was before the time when Capacitor marketing on motherboard was a thing.
- raxxorrax 5y ago> Capacitor marketing on motherboard was a thing. That is a thing? What do they advocate, the fine smell of rotten eggs when they die?
- BizarroLand 5y agoLast mobo I bought proudly talked about their "Military Grade Capacitors" which is funny because if you know anything about Military Grade that means "whoever will provide a product that meets minimum spec for the least amount of money"

- ksec 5y agoIt was a long long time ago, before Solid Capacitor were affordable enough to be used in mainstream electronics. Now they are expected in any quality motherboard. At the time they used to market brands like RubyCon for exceptional stability or another brand which I cant remember for similar marketing reason. And redundant capacitor etc.
- squarefoot 5y agoWhoever uses junk capacitors to save some cents would never ever spend more money to add a socket. That is not the problem, shitty parts are. Good capacitors do exist, but they're getting less common with time; actually you're more likely to find good electrolytic caps in a 30 years old radio than in a 5 years old one. Today some manufacturers are cutting corners everywhere and parts quality tanked.
- 101_101 5y agoso, you are not a business guy huh? lol plus it's more work & cost more to include sockets.
