How much heat do I need to pump into this thing?

Backstory:

-Been soldering wires together for 10+ years

-first time soldering a wire to a PCB

I've already attached 5 wires to different pads on this thing so I know I least get the jist of it, and I am now trying to attach a wire to the ground pad. No matter how much heat I pump into this thing the solder on the pad won't remelt. And I mean I am pumping in some HEAT. To the point that I don't even care if it works after I just will not give up till this wire is attached.

I have a propane heater on full blast not even a foot away from the thing, all the hair on my left arm is gone, parts of the PCB are literally melting and I had to put on my welding sleeve to stop my arm from burning. I have my soldering iron at 520C. And it's still not enough heat. What the hell is happening here?

Help choosing a station for multiple uses!

I would appreciate any and all input!

I'm looking to purchase a high quality soldering station for multiple uses (electronics, Jewelery, stained glass) and am wondering if there's and good advice on which direction I should go?

I'm willing to shell out a decent chunk for a good setup that will ideally last me years as a hobbyist.

I do have 5+ years doing circuit board manufacturing soldering so I would consider myself highly skilled at that, and have worked with weller, hakko, and metcal units in the past, highly preferring the feel of the weller and metcal units.

Thank you so much!

Good flux and wick

Getting set up at home (solder at work most of the time replacing gameboy game batteries) and realized I don't have flux or a braid, and the ones I use at work don't seem to be available anymore. Any reccomendations?

If it matters, it's mostly for controller joystick replacement and similar use cases

building a small home workbench and looking for recommendations for a rework station

i am an electronics technician for work and am getting back into home-brewing/designing some electronics at home after many years away from tinkering due to life pulling me in other directions.

some browsing on amazon lead me to the Yihua 948-II. looks like it will fit my needs and within my budget but want to hear from folks that have used it or other Yihua products before before i click by now.

not looking for factory floor grade stuff just something that can support some light proto work and rework and the occasional repair on a commercial item.

Soldering Station Supplies

Can I get some help in creating a soldering station shopping list? I want to build combat robots, so dealing with 22 - 18g wire, small signal wires, xt 30x, and a lot of pads. I would say I am a beginner at soldering and I am ok with the pincel's performance. I would like to keep the budget around 150 for everything (or as cheap as possible).

My current setup is a shared pincel and broken helping hand that makes it super hard to wire my bot. And since its shared the tips are never clean :c

___
Helping hands $30

Tip Cleaner $9

63 / 37 Solder $42

63 / 37 Solder (smaller quantity $7

Flux $12

Tip Tinner Cleaner $6

Fume Hood $32

Silicone Mat $7

kapton tape $9

pinecil (I already have a 65W usb C chromebook charger) $25

__

Most of my soldering problems comes with having bad helping hands / positioning so maybe I can just stick with the Pincel because I already have a power supply for it.

These are some other irons I saw, but I'm not sure if the upgrade is necessary and I want to keep costs down.
yihua 937D $50
KSGER T12 $70 - 80
FNIRSI HS02-A. $62

Alientek+T80P $42 - $78

Best budget soldering iron/station solution?

I live in maple syrup land and the only retailer available to be is Amazon.ca. Any budget soldering iron or station you recommend? I’m just buying this for a passion project. (60 bucks for the iron/station)

Also, any cheap and good shrink wrap kits?

PS5 Liquid Metal

This isn’t really an issue just more of a rare inconvenience and not particularly a soldering issue but it only happens when I’m soldering. But when I work on a PS5 HDMI port sometimes I’ll accidentally just touch the Liquid Metal. Most of the time it’s with my hand, arm, or with a microfiber cloth and not notice until it gets somewhere or what feels like ever where(I do completely clean it up and replace the liquid metal after). This also makes me get into weird positions while I’m soldering because I’m trying to avoid it. Is there anything specific anyone uses to cover the Liquid Metal while they work on it or is this only an issue for me and I’m just a buffoon. I’m sure I could use kapton tape or something like that just wanted to see if anyone else had a better solution. Thanks.

Help Needed: Identifying and Replacing Smoking Components on Brecknell 405 Scale PCB

Hi everyone,

I’m troubleshooting a Brecknell 405 weighing scale with a power issue. When powered using a brand-new AC adapter (image below), the scale emits smoke from two black components on the PCB (located near the positive and negative connections of the barrel connector). The AC light flickers, and the scale doesn’t power on properly.

What I Know:

  • The power adapter: It’s new and works fine with other devices. Specs are 12V DC, 2A, and match the scale’s requirements.
  • The issue: The two components (likely voltage regulators or transistors) heat up and start smoking when power is applied.
  • Manufacturer response: Brecknell support recommended replacing the entire PCB, claiming it’s not serviceable, but I’d like to attempt a repair if possible.

My Questions:

  1. What are these components? Could someone help identify the specific type of transistors/voltage regulators they might be? Is it worth sourcing replacements and resoldering them to fix the issue?
  2. Should I check anything else? Are there other potential failure points on the PCB or anything else I should inspect? The issue seems localised, but could it indicate a larger problem?

Additional Info:

  • I’ve checked the board for obvious damage (burn marks, corrosion, etc.) and found none.
  • I have basic soldering tools and can replace components if required, but my diagnostic experience is limited.

Any advice or insights would be greatly appreciated! Thanks for your help.

Pine64 Pinecil v2 questions

hello, i'm looking for a cheap soldering iron mainly for inserts for 3d prints but i also plan to do a little bit of soldering for small arduino projects. i found the pine64 pinecil v2 wich looked pretty good as the price on their website (pine64 dot com) is only 30€. however when searching on amazon i could only find it at 80€, and even 120€ for the v1. why is that? is one off them a scam, or am i missing something here?
