Re: What is a mechanical solder sucker?

Well according to post #4 in this thread, it's perfectly fine to replace the aluminum electrolytic caps with solid polymer ones:

Is that true?

Ok, can you elaborate on select carefully? I was only going by 680uf and 4volts.

Re: What is a mechanical solder sucker?

I've used the spring loaded ones for years and never damaged a board. I used to really hate them, but then I discovered that a bit of silicon grease injected into the tip prevents the solder from sticking and makes them work pretty good.

Re: What is a mechanical solder sucker?

Actually I guess it's a poly since it doesn't have the vents on top. So my question is can I replace this capacitor with a sleeveless capacitor? It basically looks like an all metal cap but it has the same values.

Re: What is a mechanical solder sucker?

If anyone could help me choose some 680uf 4v capacitors below:

http://www.digikey.ca/product-search...=0&pageSize=25

I don't know exactly what ESR value to look for but I would like the capacitors to be close to 8mmx8mm although there is not much choice in those dimensions. I would need the width to be as close to 8mm as possible so they don't touch each other side by side.

Re: What is a mechanical solder sucker?

Well I got all the capacitors in, not sure if I should power up the board, i'm not confident in skills. Do you guys think it looks ok or some things might be shorted once power is applied?

Best way to solder LVDS connector for beginner (and qfn) ?

by corrize

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 :

UV solder mask - high temp resistent, recomendation?

by myth77

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...

BGA solder balls not connecting - help pls

by petemanuk

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...

Hoover FM216LI cordless vacuum refuses to charge

by flat-earther

I have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.

I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.

So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries....

Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2

by acedogblast

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...
