content: There is some existing discussion here but the thread title was generic so will start a new thread:https://www.eevblog.com/forum/reviews/good-quality-chineese-soldering-station/msg5014180/#msg5014180All units support C245, C210, C115, T12.All units have ground and sleep stand 4mm connection on the back.Tons of settings: sleep, power limit, PID values, frequency of PWM for C115, calibration, etc.There is a dynamic temperature compensation option, for heavy load. Unsure if JBC themselves do this, they might.Geeboon TC20A$70:- 240W peak claimed (says 190W continuous PSU in the description)- Uses 5 pin GX12 circular connector- Tip voltage less than 2mV and <2 ohm claimedGeeboon TC22$74:- Upgraded version of above- 6 pin JBC style circular connectorTC20B$120:- 380W peak claimed (360W continuous?)- Uses 5 pin GX12 circular connector (can it handle the 380W?)- Also supports C470TA305$120:- 150W peak - 85W continuous (?)- Transformer based power supply (so 110V or 220V specific)- Uses 6 pin JBC style circular connector- guess this station is to please the toroidal fanboys.HC24$150:- 450W peak 400W continuous- Dedicated CH1/2/3 preset buttons- Exhaust fan connection on backSwitch box is available:https://www.aliexpress.us/item/3256807424641457.html$20 + shipTips look reasonable, all around 2.6-2.7 ohm:Handles look OK, seems better quality than Aixun, grip is softer. Ignore the tip I didn't insert all of the way:Measured ~210W peak for C245 and 70W peak for C210 for mains draw on power on. Less under normal use of course.GX12 connector is earthed, which is connected to the case, but due to anodizing it doesn't fully connect everywhere. Not a huge deal IMO as there appears to be good PSU separation.Overall, seems good for the price.Pinout - T210 handle - GX121 - NC2,5 - Heater+ (red)3,4 - Heater- (blue, green) shorted internally

The other day you explained to me that from the photos of the GX12 connector you can understand if the soldering station is compatible with the original JBC handles, how can you understand ?

content: Its clearly explained above:- TC20A/TC20B = GX12 = not compatible, metal circular connector- TA305 = compatible JBC connectorJust look at the photo, if its black round plastic plug with 6 or 7 pins its JBC compatible. Worst case someone had to drill out the empty space to get their JBC handle to work.edit: updated

content: Quote from: thm_w on October 08, 2024, 08:47:44 pmThanks for the explanations.Apart from the shape of the connector I thought that the compatibility depended on the order in which the pins were connected, I thought it was a question of internal connections, in some stations I saw that they change the order of the cables on the handle to make it compatible. Thanks again.

In the description there is aGoogle drive linkandBaidu linkfor TC20 firmware updates and user's guide. But no firmware for the TC22.In another review, we have this"Seller's Reply: TC22 is an upgraded version of TC20, adding more error compatibility and ground wire processing. The hardware is also different, the software will be modified, and their firmware is not universal. Thank you for using it, and welcome to evaluate the product."There is no more useful info on theTaobaopage. Exceptbuyers who complainabout the poor quality of the handle or tips.For the TA305, there is non more information on store's pages, except a link to agoogle drivewithe the user's guide and firmware upgrades as for the TC20. In the guide, a more powerful unite, named TA310 is mentioned. This model can't be found on Taobao nor on Ali, but theofficial websitethere is a new model named HC24 that looks like a more powerful TA305.Nothing more about the TA305 on theTaobao pageof the product.There is aGeeboon channelon Bilibili with few videos. There is one of theTA305 prototype, it looks like it's being developed by a single guy in his kitchen or garage! I don't know what to think about it.I'm hesitating whether to buy a TC22 or a TA305.

You have "bigger" companies like Aixun who can't even get the basics of soldering right sometimes.Also there are a LOT of positive taobao reviews, some interesting stuff in there. One mention of the cracked handle but no photo and a new handle is ~$15.QuotePersonally the light weight and cheaper cost is pro for me. Maybe power supply dies in some years if its a poor design.edit: I found one bad review, maybe they got a defective station or a previous revision?

content: It is a very, very nice soldering station, amazing. The Hanles 245 and 210 look the same as the JBC pinouts. The only note is the Stand - it is made from metal, robust but thoughtless. The contact sensing is sensitive and activates even when you touch the cleaning wire - hmm.. . You have to fix it for yourself.https://www.dropbox.com/scl/fi/vn0c24l4p5stmxpq7z2ul/Geeboon-TC22.mp4?rlkey=yevs71drzujxm07up777jrtrr&st=cb1sl6a2&dl=0Sorry, I do not have the time nor will to fully disassemble it - it needs to remove the front sealed plastic.

content: Just got TC22 with C210 handle.Can confirm that there is no voltage between the tip and the ground. Also, touching the ground with the tip does not create any problems as with Aixun units with switching power supplies. The ground connector on the unit is connected to the ground wire of the 110V power plug, and resistance between the tip and the ground connector is about 2.5 Ohms.I agree that the stand could be improved. Brass wool should be isolated from the case. And also the extra tips do not stay in the holes meant for keeping them, they fall on the side because there is nothing at the bottom. Would be nice to put a rubber block there with holes for the tips. Another suggestion is to make the stand to be the same length as the unit (or vice versa) so that you could stack the stand on top of the unit. You can do it to some degree now but it is not perfect. Alternatively, if the screen could be rotated 90 degrees, I'd put the unit vertically next to the stand.Other than that I'm quite liking it. It is small, universal (multiple handles) unit that meets all the requirements I'd have of a soldering station.

content: The lack of a sleep wake-up delay menu and existing of the sleep delay one make me suspective (the sleep delay menu is fully thoughtless - it serves only the bad stand design)., and I asked the seller about that, his answer was "It supports, the shut cable is used for", no sense - the shut signal is used only for the switch support ( Hm ..., meaning the switch has hot replug support, and the station doesn't ?! ... seller's reply)The sleep delay menu excludes proper safety tip removal except if it is at a 0 - deactivated - no sense.I used it for a week and I love the way the station works, and not everything could be perfect from the first time - it will be good to have communication at least.

content: Hi. I was able to open the switch and I can say that both the soldering station and the switch do not have proper hot tip swap. Both signals “Stop” and “Sleep” are directly sent to the station and the “Stop” is not used at all, only “Sleep” is used for the tool detection. I did not expect that! I could not see good input protection for the controller inputs! (I don’t have a schematic to estimate that, but it is what I saw)I can see each channel has 2 relays, for power and signal, both with 2-row contacts (How that guy has compensated for the cold junction – with or without the switch?).Good idea and promises ...PS - I made a mistake about the microcontroller inputs protection - I can confirm it is ok. Sorry about that.

The wake-up method is to touch the soldering iron tip with a wet sponge.Dynamic temperature compensation (default closed): Add an item in the tool menu. When the soldering iron tip is detected to have a large load, the system will dynamically increase the temperature to increase compensation for the soldering iron tip, and exit when the power drops1.06 Add shutdown direct wake-up heating, power detection sleep threshold can be set, some minor bugs.Also the filename for 1.22 says (again translated by Google)TC20_1.22_Support new background tools.gbnThat's all I could find.

You will get the plastic out slightly curved - do not try to straighten it without heat or you could crack it at the joystick place. The front board screws are just under. Look at the screw lockers of the power supply PCB to release it. Thats it.

content: Hi everyone,I recently bought a Geeboon HC24 station (£124 delivered - so, no import tax in the UK) with a SW03 switch (£36 delivered).I posted it here because it's just TC20B/TC22 big brother.The station comes with a T470 handle (the same size as the standard T245) with a nice silicon grip and two high-quality tips (C470-10D and C245-5D).Overall, it's a great powerful and compact soldering station. It has a full metal body and like TC20B It's accepting all handles from T470 to T12 (T115 and T12 not checked). Geeboon's tips and handles are of decent quality. I bought from them two additional metal handles T245 and T210 which are great - genuine Hirose connector, silicon grip and cable, ring brass tip connector and PTFE seal inside. There are a lot of settings and information such as tip voltage, resistance, and current.The SW03 switch looks ok and works well and quickly (0.5-1s) with T470, T245, and T210 handles (not tested with T115 and T12).But, there are a few issues:1 The station and switch have a sleep and hot-swap (actually-shutdown) function, but it starts heating as quickly as you insert the tip, without confirmation touch as Aixun stations do. So mind your fingers.2.1 The cradle (the weakest element) is not of great quality, and has only a sleep function (no hot-swap/tool extraction) so if you don't have a switch and you need a hot-swap the tips, you'll have to buy i.e. a T3B or T420D cradle and modify it as I did - throw away the PCB from inside and swap sleep and hot-swap cables on the 6-pin socket. I replaced the socket as well (the original one melted when trying to unsolder it from the PCB).2.2 The brass wool for tip cleaning is not isolated from the cradle metal body (just paint) so, the station is bouncing between sleep and work mode when you try to clean the tip. Only the sponge is isolated with silicon.3 Extractor fan (at the bottom of the case) is a bit too noisy (with T470 and T245 handles), luckily only when the station starts heating (10-15 s). Doesn't come on at all when T210 is connected. Also, there's no fan speed regulation, It looks like only 0-10-100%. But I'm still happy the fan is there.Update: I just received the T420D cradle. The only you need to do on it is a white and pink wires swap on the plug or PCB.

content: I became the owner of the Geeboon T20B station and immediately had the idea of "refinement" and the actual "contents" - there are only three tips and two "handles" in the basic supply. But, judging by the description, you can also connect T12 and C115 handles to it!Well, I started searching, and I even found something - this image should be added to the start post - at least it will be clear visually how the geeboon attaches its handles to the connector. With the C115, it is also approximately clear - the station will be guided by the resistance (it is twice as high as that of the C210) and the handle, with a pinout like that of the C210.Also, when working, I noticed the presence of "clicking sounds" on the tip of the stinger - as I understand it, is this the specifics of the PWM and switching power supply?another "little thing" - is that the wire length of the geeboon handles is less than 20 cm than that of similar ones from the Element company (there were a couple in stock)...And most importantly, do not pay attention to the COLOR of the wires in the picture - geebuun has it-and it is "standard" for any other C210/C245 pen!!! Only the "connection location" is important! And the color of the wire in the handle can be seen here:https://www.eevblog.com/forum/reviews/jbc-t245-handle-disassembly/ I have them exactly matched on both handles (geeboon and element)

Maybe if you have some large collection of specialized tips.Clicking I haven't used the station enough to notice, but it does happen with some Aixun stations and real JBC station as well. Can be from slow PWM switching speed as you say, maybe you can measure the output with a scope to see the frequency.

I also gave a "drawing" of the pinout of their stations with handles for GX12-5 - this is a little different.And yes, I have a rather impressive "collection" of T12 tanks, somewhat "specific", plus for some reason the Chinese still do not make cheap "analogues". for example, a "spattel" with a width of 30-40mm. And the good old "tunnel/quad" - the JBC analog stands like a cast-iron bridge (or a wing from Boeing).

content: just wanted to add a bit to the topic, but I got the ta305 about 3 weeks ago and have been using it since for a couple of times a week. It can do 140w continuous (also i think it's the max as the power bar is at 100% at 140wcan actually go higher on initial heat up and from sleep highest i saw was 147w), not 85w for about 20 seconds before tool protection kicks in as i couldn't hover it over the water at a stable rate for the temperature not to plummet(and also i was afraid of damaging the tip) additionally the station draws about 175w while doing so according to my cheap power meter.the stand isn't much of note, same issues as others have said but geeboon seems to have updated the stand with the SDC02 it seems to be well made from the pictures with silicone separating the plastic parts and has replaced the original on the ta305 albeit at a slight price bump. I've bought 2 since it comes in much cheaper than the aixun ones and the stands i bought don't seem to be coming anymore.i've also taken it apart looks good apart from the bent ground connector(needed as it would hit the transformer if not). And for anybody wants to take apart their station really make sure you heat up the front panel your more so bending it with the heat rather than prying it off otherwise it would crack, and its the same vise versa start on one side and use heat to soften the plastic and bend it down(i set my hot air station to 150c and max air flow).on a side note i got the t115 handle with it, looks fine but does get quite hot after extended usage but a t210 foam fits over it snug albeit a little thick and long.Edit: just realised the t210 handle only has a max of 30w, is it the same across the other models given that other t210 compatible stations have higher power?

content: Been using a good ol' hakko FX-888D for over 10 years but tips randomly deciding to fuse into the sleeve/collar/whatever it's called (the screw on metal tube) really gets on my nerves when it happens and has been happening more lately and the tip currently in it seems to be permanent this time.So i went looking for something new....oh boy how much has changed since i last looked at irons back in 2014.In the market for a new iron and came across this one which looks pretty well made and i don't want to pay hakko or jbc prices as they're kinda crazy in australia.Anyway, i was initially looking at the Aixun T3A but it seems to have issues that don't seemterriblebut also not great so i went looking at other options that isn't the damn pinecil that pops up everywhere...So, those of you who have had one for a while, would you recommend it? Does it have any of the issues the Aixun units have (voltage leak / ground problem etc).I was going to go with the TC22 and the new stand unless there's a compelling argument to go with the TA305 (which already comes with the new stand and costs more).The only downside I've found with moving to the "new" tech is the lack of heat set insert tips for the jbc style cartridges (unless I'm blind, i haven't found any...only T12) but that's nothing a cheap pencil iron won't fix so not a big deal even though i use heat set inserts a fair bit.I'm open to other options of course, within a reasonable budget of around $200 AUD or so that don't have issues that just get swept under the rug by companies.Thanks

Maybe it can't tell the difference between the two so has to keep power to a safer level.T210 is not that useful of a size to me, I would just go 115 for fine work and 245 for general/high power use.

content: Hey guys. I have a few questions regarding Geeboon stations. I know that Geeboon sells 2 types of stands SSD01 and SDC20. I know that SDC20 has fixed the issue of sleep mode whenever you use brass wool for cleaning the tip as it is in direct contact with the stand. Now SDC20 stand does not have the "Sleep" wire coming from the back of it, if I use the station with just 1 tool in SDC20 stand it will recognize sleep mode and shutdown mode when changing the cartridges. Do I need to make some sort of modification if I am going to use tool switch with 3 SDC20 stands?I have seen few Geeboon stations that have toroidal transformers. Did somebody probed the heater wire with scope is it half wave AC or full wave? Do other stations, with SMSP PSUs and toroidal transformer, have some sort of voltage leakage problem,not tip to ground rather to + and - of heater and to logic board?

content: Hello,I'm new to soldering and looking to invest in a reliable soldering station, primarily for working on guitar electronics.I was initially considering the Hakko FX888DX due to its solid reputation. However, as a bit of a tech geek, it feels odd to invest in something based on older technology—though I’m not questioning its quality.After doing some research, the C245 tip ecosystem seems to offer some of the best performance and precision. I even went ahead and ordered a few genuine JBC tips. That said, I can’t justify the cost of an original JBC station, so I’m looking for a more affordable alternative.Safety is a top concern for me, and I’m wary of uncertified Chinese products.With that in mind, do you think the Geeboon TC22 is a good choice for my needs? My budget is around $150. Should I go directly to the TA305 for the linear transformer?Thanks in advance for your advice!

content: Just got my TA305 - very impressed. My old genuine JBC (BT-2BWA10 analogue dial, but digital under the hood, unit) will be gathering dust I think!Other than all the extra info and settings I get, it still boots fast (some of the digital display JBCs take unreasonably long) and has a shutdown timer unlike the "analogue" JBC. I would prefer a power switch on the front though.@rexet - it sounds like a lot of people are happy with the cheaper SMPS station, I mostly went for the linear option to be traditional (note that half the added cost is in shipping once you pick the nicer stand option). The teardown pics suggest it's of good quality.If I was starting off with a fixed budget I'd spend the money you save from going SMPS on a second handpiece (get both T245 and T210), and a bunch of tips for both handpieces (chisel tips are my mainstay, much better all-round than conical). If you have anything left then the auto-switch box and a second stand (go for the better SDC02 option) will make swapping handles MUCH easier!

I’ve been thoroughly educated to see it as something to avoid at all costs 😄! Honestly, I don't mind spending a bit more to go straight for the TA305 if it means better efficiency, reliability, and safety.I don’t think I’ll need the T210 handpiece right away, but I might include it just to stay futureproof.BTW, I have seen that Geeboon offers metal version of their handles for $4 more. What is the benefit of metal vs plastic for the handle?

But if you are spending $80 on a station, you don't expect it to last forever.If you plan on doing microsoldering I would use T115 (0201, qfn modwiring, etc.) instead of the T210.Metal might be a bit more robust and sink a bit more heat, I expect its worth $4.

Buttons vs knob might be better or worse though - hard to tell without having used both.There's also another non-geeboon option of "i2c PDK1200" that I was looking at, does dual handpiece (if you buy a second stand or the full kit) and is pretty well priced, but seems to have mixed reports as to how well it behaves (there's a thread here about it). The TA305 seems to be within ~10C of correct temperature with OEM tips, though I haven't looked at overshoot etc, or a wide variety of tips yet (arrived 6.30pm this evening!).

content: New firmware for tc22 and hc24 on google drive:https://drive.google.com/drive/folders/1SwbyB3bcFrNMGOF1WSqRP2o7aefq-gPYUpdate Notes: HC24_TC22 1.271. Improved HC24 fan control logic, changing the control logic to reduce noise.2. Improved algorithm to control overshoot, reducing thermal overshoot.3. The power of the 210 can be adjusted to 90W, requiring a factory reset.Fan not used with C245 tip on HC24 . Fan used with only C470 tip.Silence is bliss.

Bottom right corner of graph screen has an undocumented "TMP MOD" currently showing "RG" but that was there before the upgrade.
