It pumps a bit slowly so that the suction is not so good I have cleaned but does not make it effectiveComment

Re: Solder suction cleaning help
Are we talking about a Desoldering Gun Station if so check and see that your suction tube is clear and that you have replaced the filters if you still have suction issues then carefully take apart the suction pump assembly and make sure that it is clean and that the rubber parts are in good condition including the tubing for the suction tube circuits for the deviceComment

pull out the piston and put silicone based grease on the rubber o-ring(s)
also, put some on the inside of the barrel.Comment

Yes, for the handheld solder suckers e.g. Edsyn Soldapullt like pic we used to clean them, and then lube them up with Lubriplate and the suction got much better. It was a weekly routine in the repair shop. That is a light petroleum grease.
The smaller metal tube solder suckers never performed any good, they are crap. If they don't have poor tolerances and sloppy piston seal, they have a wimp spring and it's just a waste of time.Attached FilesComment

Yeah, you have to take them apart, it's a messy process. Do it in a pan or on cardboard or something.Comment

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
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... -
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 :

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... -
