    Didn't have a blown cap, but I have to solder one anyway...

    To make a long story short, a poorly designed CPU fan assembly (coughhpnetserverlp2000r) ripped a cap clean off the motherboard. In fact, the pins are still on the board, with silicon on the tips. See picture (sorry for poor quality):



    The cap is a 6.3V, uF1500 Rubycon, should be easy to find/replace. So when I get a replacement, could I just solder to the existing lines there? It'd be beneficial because I can make the capacitor clear out of the way if it was on a 90 degree angle. Also, I'm unsure about the polarity. On most mobos, the white half of the circle denotes a negative polarity -- on this board, all the caps seem to follow just the opposite (may be visible in the picture; notice the other caps have the minus side facing us, while the white half of the circles are facing away?). Just wanted to get a consensus on this.

    I meant to say electrolyte gel, not silicon. My bad!

      follow the board markings when replacing that cap.looks like the white side is +
      clean out the holes and solder in the replacement.
      angling it away from the hsf is fine but keep the leads as short as you can.

        asus is opposite also.

          I seem to have trouble finding a replacement. Anyone know of any Chicagoland stores that'd carry parts like these? Radio Shack's offerings were dismal.

              Well, the operation was a success. I ended up getting Nichion (sp) Low Impedence caps. Same stats as the Rubycons, for the most part.

                  If you saw my job, you wouldn't be saying that.

                    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 :

                    LG 47LB5DF blown power supply board
                    by cmlewis89
                    Hi folks,

                    I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...

                    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...

                    HP X360 convertible battery blown fuse error, not charging
                    by drscoot
                    HP Modelnumber: 14-dh0061nb​
                    This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
                    The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
                    I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
                    And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
                    All these 3 batteries are charging...
