    Is this solder or glue?

    I am replacing the digitizer on a friends HTC One X. I moved a flexible circuit board and a copper square fell off. I was going to just re-wet the square but I stopped because the solder looked more like an adhesive. I am hoping that someone here can tell me if this is an adhesive (and what kind) or if I am crazy and I just need to wet it again. I took a close up pic with the pad resting on a screwdriver next to the spot it fell off of. Thank you for your help!

      hard to tell from that pic....but it *looks* like solder.... On flex boards, its usually glue though.

          That's glue. It was holding the pad that you lifted in place. Is the track still connected to the pad? If so, just glue it back in place... Most people recommend cyanoacrylate, I personally don't like it since it leaves residue all over the place when it evaporates. Maybe a very thin layer of some sort of tack glue.

              Thanks guys for the quick help! I got some conductive glue and it's drying now.

                  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...

                  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...

                  How to remount this?
                  by Almighty1
                  I was fixing my notebook/laptop computer and the motherboard/mainboard/systemboard standoff which is for securing the bracket that also holds the fan fell off. I would like to know what I can use to re-attach it to the
                  mainboard/motherboard/system board. It seems to be some kind of electrical conducting adhesive as it has continuity when I tested the dried out adhesive as it is probably used to ground. Does anyone know where
                  I can buy the electrical conducting adhesive online that is strong? Failing that, will first melting solder on the bottom of the standoff first and then position...

                  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...
