r/soldering

Ik it takes a lot of solder but

What do y'all think?

Idk why but all of my tips just oxidised so fast. I mean like 3-4 in 5 hours of working. The end of the top gets dark and stop working.
I use a 110V-240v/90w soldering at 330-290 c heat. And idk why it’s happening to me.

“Now they are 4 tips completely burned out.

I don’t have a brass wool cleaner.

Good Afternoon Gents,

My manager gave me permission to get a tier list for the Basic, Mid, and Top tier of the hot air guns. Pictured is the hot air gun that I ordered. The first one we had was garbage. It was the hot air gun wit the fan on the handle. Was garbage. So i improved upon it by getting the tube one, but where I messed up at as you can see is that the air and temp are on the same nozzle. So i'm allowed to get a new one but he wants a tier list and also for me to explain the differences of them all.

I deal mainly with laptops and micro pcs like the Optiplex 7000 series. And laptops are Dell, and Lenovo and some HP. The ones for businesses so for dell it'll be the latitudes and Thinkpads like T14s and etc. The main project I will be doing when I do get the heat gun is We about 11 Optiplex 7000s that have bad front USB ports and since those connectors are hard to find, I need to take them off some bad units and replace them. Since I cannot control the separate nozzles, I end up burning the piece even tho I do get the usb connector off. What I did learn about the hot air guns were that there were two types. Helical wind and straight wind, I knew nothing about a week ago. But yeah I would love to hear you all thoughts on the topic on what you guys recommend. You guys already helped me a lot with the flux/solder situation as well. So thanks again in advance!

Purchased off of Amazon really just wanted to get the smoke out of my face. I do mostly hobby soldering at home but after a 200+ joint project I figured I'd move some air. The fan is 110v @ ~ 1/4 amp

This is the best selling "Soldering extractor fan" on Amazon.

Upon unboxing I checked with a multimeter and found no continuity between the steel case, the fan surround which is also metal and the mains plug ground pin. The yellow paint and fan paint was insulating the ground ring terminal at the case.

After sanding down both painted areas at the ring terminal it now has continuity to the mains ground pin.

Be safe out there.

Hi, do you think this would be a good soldering practice desk? With some resistors and stuff of course.

First off, Im a total soldering noob. I do analog camera repair as a pasttime hobby and this ancient PCB had battery corrosion over part of it. Cleaned that off but how do i go about this now? Should i remove all the old solder and do it all new? Or only redo the black parts and solidify others that became weak overtime?

This board is from a praktica mtl 3 btw, made in the 60s or 70s presumably.

Thanks in advance for taking the time to read this and help out a newbie 🙏

this was the last straw, nobody can do a worse job than this

Looking for critique.

First time soldering after consuming loads of content online.

it took me an 1 hour to take them off. I used a solder sucker and hot air gun.

theres a tiny piece of leftover connector in the board. That was my first instance of trying to take it off two months ago. And I failed miserably.

With each passing day I have refined my soldering and today I gave another try and this is the results!

There is a typo in the title and I can't change it, the watch model is supposed to be: Casio w800h, w800hd, W-800HD-1AV

I hope google picks up on this and it gets indexed properly so future readers and see this post and do the mod themselves.

Back then I posted about asking how to solder a blob without any soldering experience. I am happy to report back that I did it and it worked!

Using this info here: https://ianrees.nz/tech/2019-09-13-casio-w-800h-extras.html

I need to add a blob to point 5 to disable dual time, which was useless to me, I didn't want keep pressing an extra button to switch modes.

At first I thought about doing it the easy way by buying conductive paint and painting it, but then I read the reviews and it says I have to bake the watch in the oven, so that was a no go.

So I took the courage to solder it (For reference I set the soldering iron to 325 degrees C) and now I did it! It looks a bit messy, but it works and now my watch is modded!

I recently changed tips on my soldering iron, but I had this issue before. The solder pools up not at the tip. Any recommendations to fix? Different tip shape, better tinning process than flooding fluxed solder?

I had purchased a 5G module for my DIY modem, but the fourth U.FL is missing the grounding ring that the receiver snaps on to...

Is this salvageable? Figure if it is it may be a good excuse to finally learn how to solder?
