I'd just like to interject for a moment. What you're referring to as a "capacitor", is in fact, an electrolytic capacitor, or as I've recently taken to calling it, anode/cathode. A capacitor is not an electrical storage device unto itself, but rather another free component of a fully functioning electrolytic system made useful by aluminum, tantalum and vital niobium components comprising a full oxide structure as defined by CAPIX.

Many computer users run a modified version of the electrolytic capacitor, without realizing it. Through a peculiar turn of events, the version of the anode/cathode which is widely used today is often called a "capacitor", and many of its users are not aware that it is basically the electrochemical process system, developed by Eugène Ducretet

There really is a capacitor, and these people are using it, but it is just a part of the system they use. Aluminum is the anode: the positive plate in the electrolytes plus dielectric that allocates conventional current to the polarized electrical device. The anode is an essential part of an electrolytes plus dielectric, but useless by itself; it can only function in the context of a cathode. Electrolytes plus dielectric are normally used in combination with an anode and a cathode: the whole system is basically anode with cathode added, or anode/cathode. All the so-called "capacitors" are really distributions of current within two polarized surfaces.

If it works it works.

Here is some constructive criticism. Replacing surface mount capacitors with through hole kinda looks like shit. But then again it takes more work to measure the right capacitor size for surface mount.

But those solder points could use some more solder. Apply some flux and apply more solder. They should be shiny.

1) Clean the area before soldering a new capacitor.
2) Pre-bend your THT cap legs into their proper position, keep them tight to the body of the capacitor so they don't float, and pre-tin them.
3) Apply flux to the pads AND legs of the capacitors
4) Use enough solder to fully cover the pad and legs, work quickly so the pads don't lift. Your finished solder should be smooth, shiny, and completely encase the leg.
If you use flux, and the right temp on your iron, you shouldn't have huge globs of solder on the board.

>> No.5904702

>>5902034
THT Caps are generally higher quality, and they're much easier to solder to the pads if you pre-bend the legs to fit.
More importantly, they're much easier to REMOVE later if they need to be replaced again, since you can snip the legs and just wipe away the leftover solder and metal with your iron.

>> No.5904714

>>5904702
I disagree that they're easier to solder onto boards. A decent pair of tweezers is all you need for smt and a rework air gun goes a long way too. Also, I'm not sure through hole tech is inherently higher quality, but thwy are definitely mechanically more secure when actually going through a hole. Using a through hole component as a surface mount component is arguably more unreliable than both. The top heavy caps will move more with any movement and create some pressure down at the solder joints.

>> No.5904720

>>5901157
See how bulbous and weird the solder looks? That's because it wasn't brought up to a proper temp.
With large PCBs like this, you actually need to sometimes pre-heat the ENTIRE board to make sure the ground plane isn't acting like a giant heat-sink and leaving you with cold solder joints.

It happened many summers ago. Back when you first started on reddit. The "retro" fad has always been about bilking stupids of their jew gold. Once it became difficult to pick shit up at a garbage sale for a buck and flip it for $100 on ebay the scammers had to invent a new source of revenue. Nothing better than a contrived apocalypse to satiate the need of the sheep to spend OPM. I actually don't have a problem with this because a large percentage of recaps destroy the console, driving up the price of my collection. And even those that succeed make it worthless to the autistic collectors who pay good money. And many that work in the short term will fail long term.

Holy shit, thanks for confirming im not the only one noticing that autistic virgin incel in his 30s always angry and throwing "brainlet retard" at anyone asking any normal question.
I even know how his hairliene is, how greasy his skin is, and his bodyfat ratio.

AN by the way, im still waiting for you to post a link to buy those PS1 laser pickups, NOT THE FULL ASSEMBLY, you said they were sold and easily found, so post ANY model you want, i dont care which one, just post the link or go fuck that beautifull female thats so much in love with you and dreams of starting a family now that you are pushing your 30s as a successfull and fullfilled individual with no mental dissorders.

>wasn't le chinkos that outsourced all this production and made us so reliant on them to begin with.

Yeah that was dumbass boomers trying to save a dollar. Don't blame me for that shit.

>or maybe just bring those production jobs back over here instead of idealizing the situation with cringey weeaboo consumer culture

That I agree with.

They don't have to look bad to be bad. A lot of the bad shit happens inside for years before it decides to exit onto the board.

Having them on for less time will extend their lifespan. If they're already fucked and ready to leak though, I wouldn't trust them to just sit there. I don't think using less processing power would make them last longer, not sure.

how do you know if they're going bad if they look okay on the outside?

You remove them and test them with an ESR meter.

It would actually be great to bring it back over. The us would have factories with the very latest robots and would blow out the asian factories for 10-20 years

I've heard the opposite that electrolytic capacitors will hold on better if they are kept in use. Source: mr Carlson's lab.

Then you wait for your shit to stop working and hope it doesnt burn up any traces or blow up expensive chips when it fails

so they can be fine one minute and then shit all over the pcb the next?

Yes.

Electronics are pretty rugged and. Built to nominal voltages amd have comparatively generous tolerances. Eventually it gets too far out of tolerance and will stop working.

then why does every repair video I've seen with a busted capacitor show it slowly leaking over a long period of time?

Why the fuck does anything ever go bad you dumbshit, holy shit. You think this is just a factory defect? Of course it goes bad over time. This was all fine when it left the factory in 1985, now it's fucked, gee did it fucking go bad over time?

huh? I'm saying it leaks very slowly and you said it could shit all over the board and kill everything in an instant

It can do both.

https://youtu.be/UBjz94K0Ci4 is being forced to fail but it's possible in normal operation.

It goes like this.
>electrolytic cap dries out slightly.
>equivalent series resistance goes up. Capacitor now has a built in heater.
>cap heats up and vents into your case
>is no longer a capacitor, now is just a resistor.

>your power supply or whatever is now fucked good and proper

Tantalum surface mount Caps also fail often because they are very sensitive to physical stress. When they bend they crack and fail short. This is bad because they are usually used between power rails and ground next to integrated circuits.

Physical stress in this case can come from thermal cycling
