I came across this vacuum desoldering iron from this Chinese drop shipper. Has anybody heard of, or tested it? Any thoughts on it's usability for casual/hobby use?
Thanks.
Thanks.

For casual use it should be just fine, although for casual use a basic iron and a solder sucker works just fine too..
If it can do through-holes on motherboards that would be nice.. at 90 watts it sounds capable..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

That's a knock-off of a Hakko 808.
Search Hakko 808 in the forum.
My only thought is you are holding up the pump the whole time which will make your arm tired.
For not too much more you can get one with a remote pump.

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
heh, they include 3 nozzles with that. more then I got in my hakko 808 (no spare nozzles) which costs (a lot) more then that thingCap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
But the real Hakko is probably better...
Although I think PCBONEZ has the best idea, one with a separate pump."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
Also having a remote pump means no vibration is transferred to the tip, making it easier to hold the tip accurately against the board. Even the Hakko 808 and its fairly smooth pump makes the tip vibrate too much for me (OK, I'm weak).Comment

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
Or get a hot air gun like the Atten 858D Dave of the EEVblog recently reviewed it. You can remove through hole and SMD components without even desoldering.
The downside is it is only manufactured for 240 volts so no dice for us in the US.
The review video:
http://www.youtube.com/watch?v=vva2t...&feature=feedu
It's around 60 dollars US shipped.
As for solder suckers you're better off with units that have the vacuum pump inside the station it cuts down on weight and fatigue especially if you're using it for extended periods. These units have a vacuum hose and power lead running from the station to the pencil tip.Last edited by Krankshaft; 04-25-2011, 08:49 PM.Elements of the past and the future combining to make something not quite as good as either.Comment

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
I thought all those cheap hot air rework stations had 110v versions?
Anyway, watched the video, looks OK for the price, I think I'd do something about those holes in the side of the fan housing though, I doubt they help airflow.
I never knew the ones with the fan in the handle were that small\light\quiet... though I think I'd still prefer one with the separate pump.
Overall it looks worth it if you want a hot air station for very cheap - but maybe worth getting rid of whatever capacitors they used, I'm sure they didn't use anything good!

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
All you need is a socket for an electric dryer and to make up a custom extension cord. [Ideally with a fuse somewhere near the dryer end.]
.
Also a 110/120v->220v transformer should be easy to find as it's only uses 700 watts.

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
That would surprise me... like he said, there was probably nothing on the board except wiring - and it's nowhere near the heater - and why would a PCB like that need cooling? Seems strange..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
Good point, but that sounds like a pretty bad design to me if the PCB heats up so much that it needs fan cooling..."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
How do you know the active part of the regulator for the heater is not physically on the other side of that PCB?
All I said is what I think THEY may have been thinking when they did that.

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
That also makes sense... I guess I'm too tired right now to think about it properly (It's midnight soon here)
I guess I just went along with what he said, about maybe cutting off mounting lugs or something, seen that kind of thing several times with cheap stuff (and even the not-so-cheap)"Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
The lug removal idea could certainly be true too but that would be rather sloppy compared to how the rest of it is built.
Just seems to me the way they opened up must have been on purpose for some reason.
That area does not get back-flow from the fan's output due to that seal on the fan's 'snout' so those holes would pressurize that area of the handle somewhat.
Also maybe the vent holes on the PCB side are for more than just looks and are in fact an exhaust port.
I guess we won't know unless someone buys one and tears it apart.

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
MY BAD
Received new mt995 de-solder gun from (shenzhenhaoyun@126.com) "goodluckbuy"/goodlucksell china FUC*** as new from factory. July 2011 now Jan 2012.
1. No vacuum Rubber bladder Installed by a moron ripped at screw fitting.
2. Second attempt at use Heater failed total.
Contacted supplier with increasing frustration of reply from *JO* obfuscation and misinterpretation extreme brevity and complete lack of warranty offers.
Every picture sent as requested ignored (holding in bare hand "hot" barrel with 410c on selector knob and heater LED on and red.
Picture of unit in pristine condition barrel virtually unheated chrome shiny.
This Company appears to be a junk shop garage door style.

Re: Electric Vacuum Desoldering Pump Solder Sucker MT995
Well that's a shame...
I have noticed with sellers like these that they often have multiple people on email, so sometimes it takes several tries before they actually do anything. I would try a couple more times and hopefully they'll do something about it.
If not, your best action may be to try and get a new vacuum rubber and heater and replace them yourself - should be cheaper than buying a whole new tool anyway!
If Goodluckbuy(or should that be Badluckbuy?) don't have spares, you could try the manufacturer: http://www.hhgj.com.cn/khzx_view.asp?id=88
Did you buy your tool through eBay? Maybe you can get them to help you..
Another thought: given the cheapness of the tool, have you checked to ensure the heater really is faulty? Could be the temperature control circuit or wiring etc has actually failed instead."Tantalum for the brave, Solid Aluminium for the wise, Wet Electrolytic for the adventurous"

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
... -
just did one.
works great.
so here's the discoveries.
the pump "modules" have 4 parts, the main body, the outside bit, the inside bit - screwed to the main body, and the diaphram.
the failure is the inside bit, it has a rubber coating for some reason that becomes tacky and breaks down - contaminating the diaphram.
so you need to clean everything to get rid of all the tacky black stuff.
then reassemble it.
*BUT*
you must put the 2 screws into the assembly only finger-tight.
if you tighten it properly the valves dont work.... -
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.... -
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... -
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
