    Solder it like a pig or leave it be?

    I got this Eizo FlexScan S1910, nice display, with not working backlight.

    I have tracked the problem to inverter board. There are two high-voltage SMD capacitors in parallel, one of them was bad. It states A683 which may be metalized polypropylene film cap, 68 nF/1000 V (got it from datasheet where was cap with this marking but in plastic radial casing).

    Removed the bad one and dispaly works. The question now is, should I keep it with only one capacitor, or should I add second one? I can only get these radial MPF capacitors here (or I may actually find some in my stock desodlered somewhere) and solder in it there, but it won't look nice.

      I would add the second one. And who cares how it looks as long as it works

          The thing is I am not really certain by those specs. It states A683 J5UV (probably date code).

          ADD// there is 23 V AC when in use. It may very well be some ceramic cap with much higher capacity. Who the hell knows… I guess 100 V rating woudl be fine? It seems to be on primary side of the inverter transformers so there won't be any higher voltage.

          ADD2// I've found some old radial foil cap, soldered it in here and the display haven't ceased to work So I guess I can call it another successfull repair;-) Will keep it running for couple of hours just to be sure…

                  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 :

                  With hot air from bellow the board, that's...

                  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...

                  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...

                  Solder not reflowing - what am I doing wrong?
                  by sircastor
                  I'm trying to fix a broken MacBook Air, and got a parts board to salvage components from. Following the suggestions of many folks here, I wanted to get in a little practice of using my hot air station (A Quick 957DW+) on the parts board so I know what kind of behavior to expect.

                  For the life of me, I can't get anything done with this thing. I have tried multiple temperatures (from 210-425c), different air speeds, preheating the board (with the hot air, just warming it all around). I have applied what feels like excessive amounts of flux (Amtech V2-TF-559) and the solder on these components...
