    Solder beading, can't make good joint

    Just like the title says. Try as I might I can't get a good joint on the cap terminals and the solder tends to bead right at the surface of the solder pads without really connecting. I'm using regular 60/40 rosin core .062" dia solder and my tip is about half that size. I'm positive the holes are fully clear and cleaned. Tips anyone? I'm thinking I should just buy a new mb.

      sounds like your iron is not hot enough or not tinned.
      remember the ground/power traces on mobo's are large and heavy.
      a good hot iron properly tinned and with good thermal mass is a must when working on mobo's.

          I know the iron is tinned so it must not be hot enough. What temp or power should I be looking for in an iron? I bought a cheap unadjustable Radio Shack 15 watt iron so I'll probably be buying a new one.
          Also, in my first attempt my computer did post, but the display was kind of scrambled and generally not how it should have been. It started to load windows, but shut off then. This happened a couple more times and now it won't post at all.

              15w is not gonna do it.
              i would go for the 50w weller.
              as for your problem if your joints are not good its like the caps are not there.

                  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...

                  862D+ solder station iron out of control when fan on
                  by liquidzorch
                  Hello.
                  I have a soldering station, 862D+, and every time the hot air gun is on, even if it is just cooling off, the soldering iron controller stops controlling. Let me explain what has happened so far, as it took a while to get to this.
                  First, the switch that turns on the hot air gun started to fail, the light came on, but temp never rose, I would have to switch it multiple time to get the gun to start heating, this was due to the contact inside being carbonized. I opened the switch up, clean the contacts, and it would work fin for a while until carbonized again. So, I ordered a switch...

                  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....

                  Lenovo IdeaPad Gaming 3 15ACH - Ideapad 3 well known solder joint issues
                  by Nagyesz
                  I have a Lenovo IdeaPad Gaming 3 15ACH, which has started exhibiting the well-known issues of the Lenovo IdeaPad 3.

                  All stress tests run perfectly, and there are no performance issues. However, the solder joints are almost certainly starting to fail. If the top two screws on the back are not screwed in, moving the screen results in a BSOD or, in some cases, a slight artifact and freeze. This is a 2023 notebook..

                  How can I extend its lifespan? Could reflow help?

                  It has ryzen 5 5500h, rtx 2050, no soldered ram.

                  Example of the artifacts:
