I want to recap my LCD monitor's psu, but i find out that the board is kind of "diferent", it has a solder layout. What method should i use to desolder and solder the caps?

Looks like standard soldering to me. Remove and replace as usual.

Also that's beauiful solder joints. Sign of good manufacture.

Hello, I'm a beginner for micro soldering. Right now I have some difficult to solder a qfn 20, I guess I put too much solder on the thermal-ground pad, the result is a corner of chip wich don't touch the board (last try).
I use a wire solder with hot air, I tin the board and chip before with iron and I use good flux.
I will have to solder a LVDS connector (40 pins, laptop pc), I saw a solder paste in seringe, good quality (it does not scatter).
See the test :

With hot air from bellow the board, that's... -
Can someone recommend any good UV solder mask? But i need a solder mask that will stand high temperetures. The thing is...sometimes i have a bigger cooper ripped from the board, lets say mosfet pad... i reconstract it with cooper sheet, then i "glue it" with solder mask...then i use UV light...and let it cool a bit. After, i try to clean the cooper of extra solder mask..and till that part all is ok. But, when i use a soldering iron to solder that pad/cooper...the solder mask gets weaker or destroyed and finally the pad is ripped again from the board .
Is there any solder mask... -
So I though in my spare time I’d set myself up repairing motherboards mainly pin damaged lga1151 sockets types.
I’m using an achi ir sc pro rework station (gave up on my Achie ir6500 - don’t recommend)
I’ve managed to get my rework profile somewhere in the correct region (after a lot of trial and error) to get the old sockets off and reflow new ones back on again, the problems I’m getting is not all of the solder balls are re-attaching when re-flow occurs. I know this because when socket is removed pads still look clean and have no solder... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
