    oh dear.. problems, please help (new to a soldering iron)

    Hi guys, performing my first recapping together with my first ever stint at soldering, and, as you guessed, things could be going better

    Could really use some help.

    1) I bought some 2700 uF 6.3 volt caps for a shuttle FV25 mainboard, these are the only caps of this spec suppled by RS Electrical, unfortunately, the legs of the cap do not fit through the holes on the mainboard. RS do not supply any other 2700 uF cap, what should i do? Can I push the cap in as far as it will go and then seal the remaining hole with solder, very dirty i know, but would it work... and if it would, would it work for more than a week?

    2) Under some of the caps are extra "blobs" of solder that run through to the bottom of the board, they don't connect anything visible, but im presuming will do something. One of these accidentlly got melted into one of the legs of the caps (they were like 0.5 mm away and im a crappy solder-trician ). Do they do anything? If so how should I go about cleaning up the mess, whats the best way to remove soldier? If not, can I just leave it?

    Thanks for all your help guys, IT IS APPRECIATED!

      1) is it so tight? what is your technique for clearing the holes, are they properly clear. The most important thing is not to force caps hard down the holes otherwise damage

      2) it is not a good idea to short the capacitor lead to another pad nearby. I usually gently run a hot iron into the solder that connects the two points to pick up the excess solder and remove the short. you could also use solder wick or solder sucker etc to remove the excess.

      guys : please advise regarding no.1 if you know this board

          Hi willawake, thanks for the reply.

          I did indeed use solder wick to remove th solder, that stuff is amazing

          Also, thanks to a simiar thread by topcat, i bought a different capacitor (3300 uF) with 0.6 mm legs.

          Thanks!

              WOW, thanks to you guys there is now 1 more system brought back from the dead.

              I really thought i'd bodged it up, but thanks to you guys it all went well!

              THANK YOU!

              Fantastic, i'm absolutely static i managed to do this, having never used a soldering iron before lol, thanks again.

                  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...

                  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....

                  Friend messed up my laptop motherboard while working on my bench
                  by Geeker007
                  Hi All,

                  So my friend was visiting and he wanted to use my solder bench to solder on some WLED circuit board. My laptop was open on the side for RAM upgrade. I know my mistake.

                  So while soldering he had too much solder on the soldering iron tip and he just shook off the soldering iron on the table itself to remove extra solder on the soldering tip and it landed on the motherboard of laptop. He then out of fear tried to remove it using solder wick and did more damage by removing some components as well. So here I am with weird situation.

                  I have not tried putting...

                  Sumsour station 8586D error H-E
                  by rmjimenez455@gmail.com
                  Hello everyone, next I have the following problem with the Sumsour 8586D 110v dual station I bought it a year ago and it worked wonderfully, now it presents the H-E error on the soldering iron side, the hot air side works correctly..... I disassembled the soldering iron head because the manual tells me that this error is due to ceramic resistance problems, in effect, I measured it and it is open, I bought a new one that is working verified in a soldering iron and nothing.... The same error continues, I proceeded to open the station and check visually, I found a totally damaged 1R00 surface mount...

                  Kaiweets USB soldering iron
                  by tony359
                  Hi all,

                  I am testing a USB powered soldering iron. It's made by Kaiweets but I believe it's also sold under other names.

                  As a standard test, I checked whether there was any voltage leak from the tip - that said the thing runs on USB-C power delivery so am I correct that the whole unit is floating and not grounded? If I check, I measure 90V at the tip but I have a feeling that that is not relevant? Maybe caused by that capacitor between primary and secondary inside the PSU? I do not see current flowing at all.

                  In other words, do you think it's expected and...
