Re: Hakko vacuum desoldering - Stations vs. Self Contained 808
The vibration of the 808 can sometimes be annoying.

I have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.
I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.
So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries.... -
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...01-04-2025, 04:11 PM -
Hi,
I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.
I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
(This board does not respond, only the LEDs light up in a circle.
The liquid damage is catastrophic and restoration is impractical).
(I bought this board to get the WiFi module and camera).
The boards are completely different in the installation of elements, even the connector for the WiFi module is different.

If you have this Desoldering Gun Station there is something you should be aware of the two screws that hold the motor to mounting for pump can come loose and make raddling noise
One note this unit has been repaired already once because of switching power supply regulator ic chip failure
Now this with the vacuum motor mounting issue yes I give this Desoldering station a very hard work out and use about every weekend to do some type of project
The fix is taking the vacuum pump assembly out and take the metal cover off and you will see the two screws on it

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...
