Misc Micro electronics, soldering, fixes, diagnostics... all that jazz!

[Jupitus]

Hey all - been watching a lot of microsoldering and repair videos recently trying to learn more about electronics. I'm slowly getting my understanding up, but was wondering if we have any local experts here anyway?

Same as you, just starting.

I got a couple of kits off ebay.

Soldering practice SMD circuit board LED electronics project DIY kit SMT PCB: UK | eBay

This project is aimed at those new to soldering surface-mount components. It allows you to hone your skills in soldering resistors, capacitors, diodes and LEDs, transistors and IC chips. The kit includes an 85x54mm printed circuit board (PCB) and 126 surface-mount (SMD) electronic components. A...

and the like, very good for practising, and comes with all the bits.

As for kit, not spent a great deal, probably less than £100, I am thinking about getting a decent light/magnifier/screen though, some are quite pricy.

Edit, saved myself a load of money by repairing my car key fob for less than £5, and that was because I had to buy 10 of the componant.

It certainly can be expensive, especially for the good kit. I'm getting slowly better and understanding what's what, but in reality I don't think I'll ever be very good given my shaky old mitts. What I am doing though is taking on almost lost causes headed for landfill and trying to figure them out... case right now is son's old HP laptop which supposedly needed a new adapter port / power switch. I gave up previously when it still didn't work after replacement, but I have finally had a breakthrough in finding a duff capacitor. A tiny one.

... and fuck off everyone, they do NOT look gigantic to me

Microsoldering definitely sounds like a way of describing soldering for little people...

I had managed to fix and microsolder my Sony XM3 headphones, tested the audio and touch panel function before putting it all back to together..... only to drive a tiny fixing screw straight through the main audio cable when doing so. I was livid.

Work mate heard my story, properly laughed at me, and told me to give it to his dad, as he's passionate about the topic of repair and electronics / soldering.

To my amazement, he managed to undo the damage I did and fixed em. So now I have both XM3 and XM4, since I jumped and bought the next model once I ruined mine.

No they don't but you look fucking small next to them.

I'm still slowly progressing on the old HP laptop... I managed to locate a capacitor which was shorting to ground. It's on 0603 component (tiny) but I did manage to safely remove that... short is still there, so next step will be to remove a 20 pin IC. Not brave enough for that yet, so just won a bid for a dead laptop motherboard to practice on... £3

Good stuff, I used to love dabbling with soldering irons etc. Thought I was the man when I got my first gas powered soldering iron.

Anyway, with your eyes being so close to ground I would expect you to easily locate a capacitor.

Thanks for sending me a picture of you and your Dad soldering stuff.

He's standing on the board between the two of them right? Why else would the kid have a magnifying glass

This guy is amazing (yeah, same one again!):
