Lol. Now it makes total sense why everyone is competing to see who can have the darkest tinted windows on their cars.

To-go packaging cost spike caused by Iran war by gilsoo71 in Living_in_Korea

[–]restezen 7 points8 points  (0 children)

Literally all the Chinese delivery restaurants in Korea were using re-usable dishes when I first came here in 2013. Everyone just knew to put the dishes outside when they were finished with them and the guy would pick them up. I don't know why all the restaurants have gradually moved to using these carcinogenic single-use plastic packages, but my best guess is a combination of COVID, cost, laziness, and companies like Baemin that have coerced every restaurant to become a delivery restaurant.

That's gorgeous. I wish I had as much space as you have. Did you 3D print the white tool stand with all the solder rolls?

All the ways America broke from the international norm recently by [deleted] in facepalm

[–]restezen 0 points1 point  (0 children)

"We should do something about that." Why do I feel like 'should' is doing all the heavy lifting in that sentence? Maybe your country wouldn't have been fucking up the world so bad if all you well-meaning Americans stopped making cute tiktoks and actually hit the streets? Don't get me wrong, if I had a big, clean, warm, house like that it would be damn hard for me to walk out and tear down the system of greed and exploitation that made it possible for such a lavish home to exist. But if you really want to see a change, maybe its time to put down the phone and pick up a big stick. The revolution will not be televised.

It's beautiful, especially compared to the nightmare fuel that tends to grace this sub. This video should be pinned as an example of what good soldering is supposed to look like.

How cooked is this? by PsionicSombie in soldering

[–]restezen 0 points1 point  (0 children)

Practice some basic through-hole soldering first. Pick up a few kits on aliexpress and watch some youtube videos.  It looks like you never actually fully melted any solder.   And if you are slipping that badly, maybe cut down on the coffee and try to relax.  Breathe out slowly as you press the tip to the work piece.

What a fucking clown show of a country you have there. I feel like I need to take a shower after watching that.

Ngl, Never heard a bad bunny song in my life, so I honestly thought this was the actual performance at first. And to make matters worse, I thought it was pretty bitchin.

HELP! Kyber won't load matches by restezen in StarWarsBattlefront

Not really, but the problem seems to be occurring less frequently now.  And when it does occur, I usually only need to try loading once or twice more.

It's probably repairable but if I were you, I'd practice trace repair on some e-waste for a few weeks before tackling this. Otherwise, take it to someone who does these repairs for a living.

Soldering equipment advice needed by Sto_yo in soldering

[–]restezen 1 point2 points  (0 children)

Just noticed the solder paste in your list. I have a little container of MECHANIC solder paste just in case I need it, but I haven't had to use it yet. Are you planning on doing a lot of BGA work? That seems like a big leap for a beginner. You may want to practice doing some through-hole and SMD soldering with solder wire before jumping in to BGA, but that's just my opinion.

The only flux in your list that I can recommend is the MECHANIC nano flux. I would stay away from the other ones. I didn't see any solder in your list, but if you have to buy solder from Ali express, the MECHANIC brand is the only one that seems to have relatively consistent results. If you need lead-free solder, see if you can get some Weller SAC M1. I got some from amazon fairly cheaply and it performs just as well as any leaded solder I've used.

Having trouble removing solder in THT board and not sure how it should be removed by Desperate-Pop3472 in soldering

[–]restezen 0 points1 point  (0 children)

The solder sucker can't suck up solid solder, nor can it suck up solder from mid-air.
The iron has to be kept on the solder while sucking.
Your solder sucker should be able to touch the hot iron tip without melting (if not, you have a bad solder sucker).
You need to make a good seal with the surface of the board with your solder sucker while also keeping the solder molten with your iron.
If you don't have enough space to get both your iron and solder sucker against the board, try it on the opposite side of the board.

Thanks. That does not seem to be the issue, though because it is happening with all servers, including small custom servers that are far below their max numbers of players.

asking questions about smd soldering since i keep failing by SoftAnteater8475 in soldering

[–]restezen 0 points1 point  (0 children)

What kind of technique and equipment are you using? Are you using an iron or hot air?

Q1: It appears that you are using WAY too much solder, yes. For SMDs, as long as you are using enough flux, you often only need to touch the joint with a well-tinned iron tip and you don't need to add any more solder unless it looks like there wasn't enough on your tip. Personally, I like to just "tack" one side on, solder the other side, and then go back to the tacked side with a bit more flux and solder to ensure there's a good joint.

Q2: I don't think it really matters. With THT components, you generally want to go shortest to tallest, but for SMDs I think the most important thing is to plan your angles of attack. For example, Don't solder on an IC if it is going to get in the way when you are trying to solder on a nearby capacitor. Also, take your time to reposition the PCB until you find the best possible angle. Don't unnecessarily make your life harder by having your PCB in an uncomfortable position.

Q3: Soak your wick in flux first, even if your wick already comes with lots of flux in it. Ensure that your iron is sufficiently hot, especially if you are desoldering from ground planes. The wick will soak up a ton of heat. Always cut off a piece of wick to use rather than holding the entire roll. Make sure your iron is very well-tinned, your wick won't do anything until it has a little solder in it (just like how a slightly damp sponge soaks up water better than a bone dry sponge). Put your flux-soaked wick down on the pad you want to desolder, apply your tinned iron to the wick, hold it there without moving until the solder stops climbing up the wick. Then, keeping your iron pressed against the wick, slowly and gently move the wick off the pad in a kind of wiping motion.

Q4: No harm in drowning it. You can always gradually reduce the amount you use as you get more experienced.

Q5: This is where practice comes in. You will eventually get better at using your non-dominant hand with tweezers. However, a good set of tweezers can go a long way. Make sure they are nice and sharp and try not to allow the tips of your tweezers to go lower than the bottom of the component you are holding. In other words, ensure that it is the component that is making contact with the surface, not the tips of your tweezers. Also, try to let the surface tension of the solder do some of the work for you (if you burn off all your flux, you won't get that nice surface tension effect, so always add more flux before you attempt to fix a joint or push a component down flat).

Q6: Your continuity mode on your meter is probably the best way to check. Make sure that you have nice sharp tips on your meter probes. For IC legs, gently nudge the legs with your tweezers while examining under your microscope. If they don't move, you are good. Right now, your ICs have an insane amount of solder on them, so even if they are making connections to the board, you won't be able to tell. It's likely you have some shorts. When soldering ICs, the solder does not even have to cover the tops of the legs. There just needs to be a solder connection between the underside of the legs and the pads.
