content: Hi there!I'm an hobbist electronic guy and I would like to buy one of this chinese soldering station all in 1, I really know that are the best of quality like Hakko o some other best brand but I really do use it time to time so I would like to give them a chance.I have seen this AOYUE Int968A+https://www.aoyue.eu/aoyue-int968a-repairing-station-hot-air-soldering-station-3in1-with-tweezer.htmlthat just have everything expect the desoldering gun so my question is, is that possible to attach the desoldering gun to the vacuum inlet that is currently used for the smoke adsorber?

content: I know this is old but one of the only two threads that exist on this topic. the other is here:https://www.eevblog.com/forum/beginners/help-desoldering-through-hole-components-with-an-aoyue-968a/msg487784/#msg487784Thought I would keep from clogging google with another thread and just piggyback here.I found this post and the other because I have the 968A+ and I have made a simple modification to attach a desoldering gun to it. The short answer is that with a jumper wire between pin 6 and the back of the "smoke absorber" vacuum switch (or 2 other places depending on how tidy you want it) you can make this work as though it was always meant to do it! You'll also need to make sure of the wiring of the desoldering gun and may need to replace the connector it comes with like I did.I recently began a significant salvage effort on a pile of old electronics. The solder sucker was just not cutting it not to mention my hands were starting to hurt and I hadn't even finished one board. I don't need/want yet another box on my bench and I had the same thought as you - this thing has a very strong vacuum in it already, can't I just use a desoldering gun for it?The Aoyue desoldering gun has been discontinued, so I looked for other options on the Amazon etc. I landed on the one below but it is 8pin so I also ordered a few GX-16 6 pin connectors to fit the 968A+. I had checked the specs of the station it is compatible with and it is 75W so I figured it was safe for the 70W of the Aoyue. I cracked it open to figure out what wires did what, drew a simple pinout, then wired up the new connector.https://www.amazon.com/gp/product/B07Z76P231/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1Simple trace tracking showed me what connects to the switch, which pulls low to tell to controller to turn on the pump. Therefore, the switch can share ground with the thermocouple. Thus the jumper from pin 6 to the vacuum switch and the switch at the gun handle connects pin 6 to controller gnd.Plug it in and voila, works beautiful. Happy to put up pics or help anyone interested in doing this.

content: Hi kronk!Thank you for this post. I will also try it.It´s almost two years, can you still post some pictures? I am not 100% sure which pin is #6.

content: This thread helped me, so attached some pictures for anyone who is also looking to adapt the YIHUA#948G themselves.The GX-16 6-pin is labeled on the connector but I've numbered them in my drawing (male end). As follows:1: Heating Element (White)2: Heating Element (Yellow)3: Ground (Green)4: Thermocouple (Red)5: Thermocouple (Blue)6: UnusedCan't guarantee the colors will match what's connected in the gun so definitely check. I melted the thermocouple wire on my first go, connecting it to the heating element power.I could've re-used the black wire coming from the switch but I cut it out thinking I just wouldn't use the switch.Ended up running 2 new wires from the switch to some leads from inside the station, those are connected to the smoke absorber switch.

content: I'm curious to see your design. I made a similar modification using the same 8-pin gun, except I replaced the female panel mounted end to 8-pins. I didn't consider checking the possibility of shared grounds.I was being cautious as to avoid damaging the station.The 968A+ has an interesting design. It's eerily similar to the slightly higher end models which support the T12-like soldering tips. I recall measuring its heater's input voltage using a multimeter and noted it ramping up and down and stopping every second or so. I haven't tested it, but if the temperature sensing is only read when the heater is off, it might just be possible to wire a T12 soldering iron to the 968A+. It would entail wiring the heater and sensor in series such that the sensor.

content: I made this modification tonight and while this thread was helpful I found it very unclear exactly what to do. I'm gonna try and explain what I did and hopefully it will be helpful to someone else who reads this. First off let me make it clear that I have the Aoyue 968 not the 968A+. The first issue with the 968 is that the GX-16 plug on it is a 5 pin not a 6 pin and all 5 pins were used. This was an issue as you need the unused pin 6 to jump to the vacuum pump switch. I switched out my 5 pin GX-16 with a 6 pin one. This required modification to the PCB in order to make the 6 pin fit properly but it wasn't too terrible, the pin out stays the same you just have the additional center pin. So at this point I basically have the same setup as the Aoyue 968A+ and so the rest of this post will be for the Aoyue 968+. Additionally I purchased the desoldering gun from the Amazon link that a previous poster linked. I'll link it again at the bottom of this thread.1. Connect the green wire from the bottom terminal of the soldering iron switch with the black wire from the bottom terminal of the smoke absorber switch with a wire tap splice.2. Connect a jumper wire from pin 6 (center pin) on the GX-16 to the top terminal of the smoke absorber switch. (IMPORTANT this switch has 2 sides. The terminal you need to connect the jumper to is to the right side of the switch, to the terminal closet to the air flow gauge. This will turn the pump on when the gun trigger is pressed. If you attach the wire to the left terminal it will only turn the red LED on and not the pump.)3. That is everything that needs done on the inside of the station. The rest of the work to get your desoldering gun working will assume you purchased the one in the Amazon link.4. Cut the GX-16 8 pin plug off of your desoldering gun. Attach the wires as shown in the diagram posted earlier in the thread to the new GX-16 6pin. I'll upload the pic again at the bottom of this thread. The unused pin 6 will attach to the black wire.5. That is everything required for connecting your new 6 pin connector to the desoldering gun. The rest of this post will be instructions for modifying the desoldering guns internal wiring.6. Open the desoldering gun by removing the 3 screws in its body. Once open cut the small blue wire coming from the cord away from the trigger switch. Cut the small blue wire coming from the tip of the gun away from the larger blue wire running to the trigger switch. This she leave you with 2 unattached small blue wires and a larger blue wire attached to the trigger switch.7. Attach the 2 small blue wires this will require a small amount of wire as they will be too short to connect otherwise. Connect the larger blue wire that's connected to the trigger switch to the red wire. I recommend connecting to the red wire where it comes out of the cord before it connects to the red wire coming from the tip of the gun as the stranded wire is much easier to solder to them the solid single wire coming from the tip of the gun. Tuck all of your wires neatly and close up the gun, you have completed the modification. Now whenever you pull the trigger on your desoldering gun the vacuum pump on your station will come on enabling your desoldering gun to work properly.https://www.amazon.com/gp/product/B07Z76P231/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
