Purpose of this guide it to show that in a pinch you can fix some really small problems without lots of money or equipment. But you must have patience.

Problem was broken power connecter on grandsons Kindle. Removed bad connector and broken trace came up with part. New connector also shown.
-
I used a soldering iron with a 700 degree tip and de-solder braid to remove defective part. Hot air gun would have been a better option but I didn't have one.

-
After cleaning up the board and reseating new socket I simply resoldered in place. Now with the new socket installed, I needed to connect the unsoldered lead to the data port on board.
-
To remove the coating on the board where I needed to solder , I scrapped away the coating with an Xacto knife.
-
-
-
Stripping and tinning a piece of 60mm wire I layed it in the path where I needed to attach. I bent the wire to give better leverage.
-
-
-
-
Putting a piece of electrical tape over a bent wire kept it in place
-
-
-
Using a fine tip on my iron , I again used a 700 degree tip , dabbed the area with liquid flux and soldered the wire to the lead and exposed trace.
-
When done I removed tape, cleaned flux off and trimmed wire to length.

-
Not very high tech, but it got me through this without a proper scope. In this image I was verifying I didn't have any solder bridges on socket.
-
When everything was cleaned back up I put the Kindle back together and it charges and plays like it should.
-
When I was done soldering I used my iPad Pro 9.7 to take hi resolution image that I could view and blowup to ensure the repair was intact and clean
-
using this technique, you can get yourself out of a pinch by repairing an item half the length of rice ,and half as thick.

I am a tinkerer lol and am getting into building racing drones. could you pls tell me where a good learning guide is for micro sodering?? I've been practicing on old boards and whatnot but when I try soldering a wire to the board the solder wants to ball up or not attach the wire. also is cleaning the board important? pls help its so frustrating!! lol and any general tips or tricks for soldering would be GREATLY appreciated friend
Newbie repair tech here. Did you remember flux? Cleaning the board is really important, use at least 90% isopropyl alcohol with a toothbrush, then dry it with a Kimtech Kimwipe or cleanroom wipes. Always use flux (it’s essential), but be sure to clean it off once you’re done. Northridge Fix on YouTube is good to watch. Learning guides are helpful, but one of the best ways to gain hands-on experience is by working at a repair shop that handles HDMI port replacements if they are willing to train you, especially if they do micro-soldering. I’ve noticed more shops opening up lately, which means more opportunities in this field—that’s actually how I’m getting started. You can make a lot of money in tech and micro soldering, from what I've heard. Wishing you best of luck :)

Cleaning after soldering really depends on the type of flux you use. Some are cleaner than others. Use an inexpensive microscope. Look at these skills tutorials: Soldering Skills. Be patient and enjoy.
If the old solder is relatively clean and there’s no excess, would de soldering still be “necessary” to make proper connection? Or could you just melt a little more solder on them til enough of a ball is present to reattach the part and have solid connection? (Part in question is a fan socket for a mid 2012 13” MacBook Pro)
it’s easier for me to attempt micro/soldering rather than pay $100+ for a new board. It’s dead already, right ?
I’d like advise in a few areas. First, equipment. I need some decent helping hands and vise to keep the items steady. A pen style iron and station. Second, when is a desoldering gun appropriate ? Third and most importantly, I need to know how to solder a post that has broken flush with the pcb board.
