    ISL95880HRTZ desoldering temperature

    Hello,

    I bought from China ISL95880HRTZ (3+1+1 Voltage Regulator with Expanded ICCMAX Register Range Supporting IMVP8 CFL/CNL CPUs) chip, which I think is not the original one, but anyway, I tried to resoldering it with a 380C hot air station. Seems soldering is pretty good, but the laptop doesn't work (it worked before, but still had some problems with power delivery).
    Is there any big chance, that they sent me two fake ISL95880HRTZ chips or did I just use too big temperature for desoldering? I will try with another chip, but I can't find any info about the maximum desoldering temperature in the datasheet for this chip. Which temperature is safe for most chips like this?

    Maybe anyone knows? Or have some idea?

      I've ordered IC's from reputable sellers and I still got a dud here and there. I am not so worried about the 380C rather the time you blasted it with at that temperature. Then it also depends on if there was a preheat on the bottom of the board or not and other things.
      I usually warm the board and surroundings up, then I hit the chip on 380C and it comes of rather fast. Also depends on chip size and nozzle you use.

          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...

          Asus Chromebox CN62 - wrong chip put on BIOS reader
          by BMCappelletti
          Long story short:
          - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
          - gave the computer to his son a couple years later
          - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
          - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
          (seems like the story was not that short)

          He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...

          Hello, anyone here have updated ezp2023+ chip database in .dat file format.

          I need to add w25q256jveq chip but I do not know what data should I type.

          I'm using the ezp chip dabase editor posted from here https://www.badcaps.net/forum/troubl...ro-programmers

          Desoldering - soldering BGA chip close plastic mini fpc connectors ?
          by corrize
          Hello, I need your advise please ? I need to remove and replace the BGA black chip with fpc connectors around. The PCB is small, from camera.

          There is no plastic component directly under, on the other face, (only fuse and oscillator I can remove if they are sensitives to heat), but there is a lot of very small smd components I don't want to desolder by mistake.

          I have :
          - hot air, and a           ll stuff around
          - true kapton tape
          - 140 and 180 degree soldering paste
          - bismuth
          - little hot plate 250 degree max
          - the new BGA chip with probably          ...

          Acer e15-e5-576g-5762 bricked. Bios chip won't interface in AsProgrammer.
          by inck243
          Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.

          The BIOS...
