    Removing SM chips

    Hi does anybody have experience with removing surface mouted IC s and the like. I have managed to do this in the past with small deivices ,but it is difficult to do without damaging the chip or the pc print .
    I understand there is a solder available which stays molten long enough for you to remove the device easily .
    Any body know any thing about this ?

      It's called ChipQuik. There are several demo videos on YouTube.

          You can order a sample from the chip quik website:

          http://www.chipquikinc.com/

          And it really does work like they show it in the videos. I don't do surface mount stuff that often, but it's certainly useful when I do.

              Solder wick? Stuff works quite well for surface mount, but you might fry the chip...

              Yes chip quik is a good solution.

                  A SMD hot air gun is a lot cleaner than chip quick and solder wick and the chip is usually fine. With a little experience swapping SOIC-8 chips is easier than it swapping DIP-8 chips. Hot air has a lot of other uses too.
                  sig files are for morons

                      I use a hot air gun as well sometimes, just need to be careful not to heat too much, since its not as precise as any professional equipment for the job. In some situations you might not want to use one since you might desolder whats on the other side of the board or close to where you are working. Some tinfoil or sheet metal with a hole in it could help lead the heat away from what you're trying not to desolder.

                          true, like reballing

                                  Best place to source RAM chips? 8GB 820-00850 boards to 16GB or 32GB
                                  by ugamazing
                                  I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"...

                                  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...

                                  Hi,
                                  I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
                                  I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green

                                  For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct...

                                  recently struggled to remove BL0202 backlight chip
                                  which had red residue of glue underneath
                                  as well as annoying laquer over the top and surrounding area.
                                  i had to use more heat than i like to remove it
                                  which can cause bubbling of the bcb
                                  i used two different types of flux,but it was the glue causing the problem .
                                  just wondered if anyone has had this problem ,and if there is any solvent that may loosen the glue before desoldering?
                                  (some vestel fets are also glued the same way)
                                  this was on a LG47 LB585V,

                                  [RoG Ally] Fault in one of the onboard RAM chips. Any way to diagnose which?
                                  by Prott
                                  Hello dear badcappers!

                                  The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?

                                  Backstory:
                                  After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.

                                  If there is a way to narrow down which memory module is faulty it would make my life much...
