    Ram Modules with undderfill - tricks for desoldering

    I'm working on another Lenovo E14 gen 2 AMD here which has a ton of errors with the factory soldered DDR4 ram chips. I do have a donor board here from which I'd like to use the modules and swap them. Unfortunately, the modules are glued down with underfill, which i have never worked with before.
    I tried with a lot of heat on the donor board but the modules won't come loose.
    Are there any hint or tricks when it comes to dealing with underfilled chips/ic that could help here
    Thanks

      Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
      by sam_sam_sam
      I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

      One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

      Zotac GTX 1080 8GB / No video / Error reported on all memory modules!
      by gabrielA7
      Hi guys!!

      I have this video card on my bench, it turns on and the screen goes black!

      I used MATS but it showed an error in all memory modules, when writing!

      I once got a 1060 with the same symptom, all modules were defective, I rebaled the GPU and it stayed the same.

      Remember that I have all the debts ok, 1.35 Vram and such!

      Could the problem really be in the GPU?

      Could it be the BIOS?

      Thank you in advance!​

      HP EliteBook 840 G6 how to dump without desoldering
      by hans_meier
      Hi,

      I have an "HP EliteBook 840 G6" and would like to know how to dump the BIOS flash chip without desoldering. Putting 3.3V on VCC of the BIOS chip with a programmer does not work (seems to enable the PCH). I have read some general notes about connecting the CPU reset to ground or to bypass oscillators. There does not seem to be a reset line for Intel i5-8365U. Just RSMRST, but it's only accessible on the other side of the mainboard. Is there an easy way to dump the flash without desoldering and without removing the mainboard? Does anyone have experience with this? Maybe...

      ISL95880HRTZ desoldering temperature
      by Dreigas
      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...

      18VDC PSU completely dead - ZD-915 desoldering station
      by armini
      Hi everyone!

      Three years ago I got a ZD-915 desoldering station which failed just after a few months of light use. During a short desoldering session, the station simply shut down, and since then it has been completely dead and unresponsive. The failure was silent, without any pops.

      Due to a lack of time, I set it aside and didn't look at it.

      Yesterday, I took it apart and did some basic measurements. The 18v terminal shows 0v. In addition, there is no visible damage to the board itself.

      According to replies in 18VDC PSU has dropped to...
