Thread 106938189

What a bullshit video. How the fuck does that big hot air nozzle not make all the surrounding caps and resistors not come loose? Then at the end, there's something odd going on when that big blob of excess solder is removed.

Just a cheap 60W iron I can change tips on.
I need to get a hot air station soon.

>>106938214
Low airflow.
>Then at the end, there's something odd going on when that big blob of excess solder is removed.
There's a cut.

>>106938244
I get the low airflow thing, but still, the board isn't on a preheater. I guess I suck at hot air work.

Miniware TS80p, a cheap chink Pro'sKit desoldering station and some of the cheapest magnifying glasses and lenses that AliExpress has to offer. 120watt equivalent LED bulb on an office desk lamp stand. Lead-free solder from a local component retailer.
I mostly do repairs of through-hole components like DIP chips, capacitors, game controller analog sticks and such. Every now and then make or service a cable.
Has served me well so far for everything I've needed. Getting into SMD soldering would be super useful but my hands aren't good enough for that kinda shit.

>>106938214
looks ai to me

>>106938214
nah, it looks normal to me. the blob is the excess solder from the under thermal pad, it emerges when the chip is pushed down. Also you can easily hot air solder without disturbing the other components if you know what you are doing. (correct air pressure setting and nozzle)
I solder professionally.

a Yihua 995d+
have several kinds of solder, but my favorite is SnAg, it's lead-free but has same tensile strength as leaded. for flux I usually use traditional solid resin

For at home hobby stuff, I have use a Hakko FX-888D and a Quick 861DW

>>106938189 (OP)
$20 chinkshit Harbor Freight soldering iron, a tube of leadless solder, and some flux. For someone that just replaces mouse parts it just works.

>>106938189 (OP)
if I was doing the soldering in that picrel, all those tiny passives would be stripped away and combined in a single blob of solder.

>>106938189 (OP)
where does all the extra shit go once he is finished?

>>106938397
His lungs

Yihua 852D+

>>106938189 (OP)
do you REALLY need to cram all that shit to solder a chip?

>>106938368
Though despite what I said. it is a much better idea to surround the area with Kapton tape. its more of just a flex really.

>>106938430
I think he could maybe use a bit less flux, but other than that, yeah.

>>106938189 (OP)
got that japanese desolder gun, best thing ever.

>>106938430
If you want to reliably solder it properly, yeah.

I'll leave this to the lower caste thank you.

>>106938567
t. no hobbies

>>106938214
Low temp solder paste I'm guessing (down to 138°C)

>>106938189 (OP)
What was the point of adding new solder, removing it, the adding new solder again?
What was holding that tiny solder wick in place?
Why use paste instead of normal solder?

>>106938189 (OP)
this video made me laugh I was expecting it to keep going and him to start piling on more and more bullshit.

>>106938189 (OP)
second hand Hakko 936 I picked up back in 2009, and then the little tidbits like desoldering pump, desoldering wick, and so forth. No cup thingie with wiring that it supposed to clean the solder tip, I read that crap will slowly kill your solder tip when it can last many years.

A stupid habit in the past was simply scraping superficial oxidation off my most used tip. Retarded. That eventually ruined. My Just Works Perfectly solution since has been to put a bit of paste on the iron tip while hot and immediately add solder and then quickly scrub off with the damp cleaning sponge that I always use. I haven't bought a new tip in years beyond what I picked up years ago. My iron remains in great shape, but the internal circuitry of the main box needs a checkup to see if anything is starting to drift too out of spec. I picked up a Hakko FX888 not long ago as a backup unit, plus it can help me service my 936. I also though of trying out Dual-Wielding irons for certain kinds of SMD parts, but have yet to get around to experimenting.

>>106939337
I definitely want to pick up a hot air tool now as that is what I am missing for QFN chips and the like that my Hakko units will be useless for.

>>106938189 (OP)
I'm seeing solder paste these days, so what's the use case? No, seriously. Normal solder works perfectly already, so wtf?

troll video

kek I can design and build my own shit brainlet

>>106938715
>>106938746
it's actually proper procedure

Why would one sell a water-cooled 3090 without any cooler just the pcb.
reason given: upgrade

>>106939835
Fuck off, Big Flux shill.

>>106938189 (OP)
Holy shit, that was so incredibly satisfying to watch.
Mesmerizing.

>>106939605
Women with tech skills are as common as those "engineers, technicians and scientist" among the people coming via row boats to Europe.

>>106938189 (OP)
I've been using a cheap Yihua soldering iron and hot air station for a few years now, and I do not have any major complaints. I should probably get myself a stronger iron though. I sometimes struggle to heat big ground planes.
>>106938375
>SnAg
Where are you getting it from? SnAgCu and SnCu are easy to find, but I don't think I've ever seen SnAg. Also, why the hell is it so expensive?

We really need an electrical engineering general on /g/ since /diy/ is so slow.

Imagine the (burnt) smell

>>106938214
It's real soldering footage mixed with AI-generated soldering footage and repeated with AI using different seeds.

>>106938407
I know Im not the only one that I find soldering emissions addictive to smell

What the fuck do I replace it with lads?

Chicken I guess.

this. that shit is one post per week or something. repairing tech or making tech belongs here

flux is life

>>106938189 (OP)
It's just an exhaust vent hooked up to a lead melting oven.

>>106938189 (OP)
aliexpress pinecil clone running from power bank, aliexpress cheapo hot air gun, aliexpress flux and consumables.
will probably get cheap microscope in the future

>>106938244
>I need to get a hot air station soon.
Don't even think about 858D and clones. Go straight for something with a real blower in the base station and 1000W or more. Atten 862D is a good cheap one I hear.

>>106940461
I touched a heatsink in a power supply of a powermac g4. I think it was off but my finger got fucking seared regardless. What an awful smell it is.

>>106941325
depends on how often you use it. for the random once in a blue moon repair the cheap ones work just fine
if you got a repair business ye get proper tools

>>106941352
Did it sizzle?

>>106941419
lick your finger before quickly tapping something you suspect as being hot (Leidenfrost effect)

>>106941441
Yep.
Remember to not forget, too...

>>106938715
>>106938746
the wick and the extra initial solder is for cleaning the old solder which you dont know which alloy is and using one that you know how it works, also if that alloy is lower temp that the ones used in the board is easier to not fuck up the other components.
using paste in that context is just more convenient, but you can use wire solder

>>106941441
Ledenfrost effect more like divine intervention. Thank God but don't count on him to save your sorry ass when you do stupid shit next time.

>>106941510
if you boil water it will never go past 100C no matter how much energy you dump into it. all the extra energy goes into creating steam. but water won't go past 100C (at sea level whatever). various materials have various boiling points. that's how you distill various shit
anyway, having some water-spit between your finger and something hot means water will lock at 100C until it boils off, even the 100C steam will cause less damage for the short while it takes, than fully contacting something >100C directly with your skin

>>106941556
Nice explanation.
Something I did recently was to pass the soldering iron from one hand to the other, without looking since my attention was on something else.
Instant regret.

>>106941851
yeah tinkerfags know soldering iron burns. but those are ~300C so things happen fast. comes with the territory

I failed to solder an fm chip to my sega master system. Now the audio randomly fluctuates

I have a basic hakko iron that I bought for a little operation and a little fan to pull away the lead solder fumes.

>>106938189 (OP)
Same as it was ten years ago. Once you get a good set of tools, they'll last you a lifetime.
