Re: repair/replace solder pads
Depends a bit on how it looks. If its not very sensitive i just put a solder blob in place. Sometimes i patch it with a leg from a resistor or similar. There are loads of ways to do it, and depends a bit on how things look.

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Hi all,
i got a A1466 logic board for spare parts but it looks like the SMC ist bad. I got several spares but somehow i was too fast while removing it and ripped some pads off. You can see the damage attached.
Just for experience i would like to restore the lost pads but before i start (haven't done this before) do you have some hints or tutorials how to do it?
As written i want to improve skills so it doesnt matter if it takes longer. -

I have also bought a spare set of LED strips for the tv also.
I want to be able to replace singular LED's in the LED strips if I need to, but I am not sure what value LED package to buy from Ebay in the UK.

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 :

Hello All,
tl;dr: minimal electronics experience and my first repair, lifted 8 pads off the laptop display LED controller board when attempting a connector replacement, options are attempting pad repair or jump wiring.
