There's a depressingly common failure mode on this sort of construction with Bosch ECUs - the big bits fall off. Typically the larger tantalum caps just come adrift. They can be repaired, but it is a bit tricky as one would imagine, mainly due to the many fine & fragile bond wires present that are embedded in the gooey conformal coating that has to be cleared out the way to perform the repair. They seem to love bolting them to hot bits of engine for some reason, so lots of heat cycles.

Impressive how quickly you resolved the issues. Nice skills, very knowledgeable. Do you have a bachelors degree in computer science or electronics?

I have one of this DAC, the only issue is the LEDs for sample rate are all dead.

Nice di you want to sell it? Whereabouts are you based in the UK

Thanks for this video too! I’m going to try using some AIM brand led free solder that a KZbinr recommended. Do you ever use lead free? Is the solder you used in this video leaded? Thanks again!

Thanks so much for making this. It was super helpful (had no idea what to get or expect)!

Looks like a nice and quite economical alternative to extremely expensive Hakko options.

Wow - blast from the past there. I used to do a lot of side-projects for Richard Martin Lighting back then. I recall visiting Clay Paky with Richard to negotiate the purchase of his first few units. I designed and built a portable controller for him that was based on the operational design of a Thornlite 120 studio lighting desk so the LDs would be familiar with it. A friend did the software, I did the hardware. As one commenter said, they used these a lot on TOTP, Richard supplied their lights for a very long time. Before the Scans came along, and for a fair while after, I did control boxes for quite a lot of Richard's lights. I confess to being responsible for a rash of UFO sightings in my local area....one light unit in particular made the local papers. I was testing a control unit of one of his latest creations, in my garage, firing it out onto the clouds on a dark and somewhat misty night. The effect was simple enough - HMI lamp, strips of mirror attached to a flexible rotating & articulating platform, with a selection of dichroic filters. This created bars of light that span and zoomed, depending on what you did with the actuators. Happy days...

I like how when she says 5 it sounds like a US Southerner.

Can you advice about your power supply unit? I have 100W GaN USB-C (WEKOME WP-U155) with 100W USB-C cable, but I can set maximum 65% of power and I wonder if it's the charger fault or I do something wrong.

The black glue is anti vibration to stop the heavy caps snapping off during transport

Boss greetings from nigeria a big fun please i need just the stand i have a microscope were will i purchase just the stand

if this expensive device couldn't desolder at low temp without preheater in mass ground plane board, then i guess cheaper atten st862 + preheater can do the job.

Tone the music down, please. I watch these at night when people are sleeping and it's just a pain to hear you then get blasted out with the electro-boom.

Thanks for sharing the video, I've fixed mine by replacing the small 10uF capacitor

Excellent, analysis, repair and info! Thank you very much.

Tengo la mía con error de fan y no se que aser nadie tiene esquematico

Which do you recommend the Quick 861DW or the Quick 861 Pro?

Most viewers do not necessarily understand a solder iron power ratings nor the ohms law. It would be best if you mention the JBC cartridges are 2.5 ohms rated unlike others that are 3.5, 4, or 5.6 ohms, and thus consumes more power and are suited for stations that deliver the required power for the cartridge.

You may want to add the steps of using a power consumption meter and validate advertised power ratings by dipping the iron in water and monitor its recovery to the set temps. Such as this one - kzbin.info/www/bejne/iHnahGx5eap8ia8

Steve, if you want to get into comedy videos, find a Yorkshire farmer and get him to try the voice commands!

Love the repair videos. Subbed.

Really cool, but I already have a Hakko :) Though if I didn't - I'd seriously consider this.

Trying to repair one of these and I cannot find a schematic anywhere. Static noise on all audio inputs.

Voice control is a great accessibility feature, for those technicians without arms. It's also neat that it doesn't recognize proper english accents, instead favoring those of us with a broken english. I'll take five, thanks!

That really is a "light weight" motor driver pcb, so light weight i thought it was a photo of the pcb like big clive does sometimes!

New Chinese camera… it goes CRICKKK. Maybe VC with a hint of crick may help? As always clear and constructive video. 👍🏻

Voice control 😂 hi quick you are so quick 😂 good bye😅

like i need another Chinese spy in my shop

Voice control, no thanks.

For this price its a bargain. I expected to se a $500 tag, but under $300 its a no brainer. Im sure someone will hack it and improve the voice commands, altough i dont see much use for them. Plus the long response is annoying, but I'm hooeful someone with more free time will "fix" that.

In the programmed thermal profiles, are there only 3 segments or can you have more than 3 segments?

That's poor performance for such an expensive machine

I'll stick with my TR1300A

Hi Steve, thanks for another great video. Do you have any incoming videos for a desoldering station? My Pace ST-125/SX-90 is not performing anymore, and I need something to upgrade to. I would be nice to find something that can suck solder from through-hole components with large ground planes. Thank you!

I'm pretty sure that the fake amtech is really just Kingbo. So - yeah, Kingbo IS a good flux. Reliably, so. I've recently tried the new Mechanic M35 Nano Flux Paste. It is good for only the cleanest easiest of BGA jobs...NO cleaning on offer here! I use many different fluxes for different purposes. From plain rosin mixed with isopropyl alcohol + glycerin - to johnson chemical Ruby Fluid zinc chloride flux. Depending on the job. There is no one flux for all jobs.

Humorous they chose a southern US accent for the voice.. LOL

Voice control 🤣Why? No thanks. Gimmick. Remove the voice control give me a better unit with more nozzels.

I think they should have focused the engineering efforts on the core functions of the unit itself and told marketing to take their voice command ideas to a toy manufacturer. Outside of novelty I don't think anyone is going to be using that in a professional setting.

Would also be a lot better if it also only acknowledge the wake word with a "hey" and not the rest of it. It seems very annoying to have to wait for it to finish before giving it the command.

What would be better, Aixun H314 or Quick? How does 15-50m/s airflow convert to liters per minute?

Great work

Trees can interfere with signal and speeds , and worst of all is rain and wet leaves on the trees walls and roofs . (5g struggles to penetrate water shielding on my experiments) mounting higher up will give about 12% improvement on wet days at least.

brilliant work, but its probably not worth it, at least subjectively the sound from CA dacs would be described as "sterile"

Love ❤️ this !

Refreshingly gimmick-free user interface. I've tempted by an Aixun T3B to replace my very aged Weller PS2-D/TCP 45 setup until seeing this...but then you put me off with the comments about the proprietary tips :) Thanks for the review.

What’s the point of repairing it, you can buy one for £50 that would perform better.

Very thorough diag & repair - nice one. A cynical person might suspect that these manufacturers know full well what happens to these glues over time and are perfectly happy about it.....a slightly less cynical person might suspect that the Chinese manufacturers they all use are less scrupulous than one might like and are using cheap alternatives to the specified adhesives. An entirely non-cynical view might be that the manufacturers have been duped, a bit like the old fake capacitor electrolyte scandal from a few years back. Whichever is true, it seems a good first step with anything like this is to remove all traces of adhesive, inspect very carefully for damaged traces & vias and go from there.

Yes, I love mine. It was expensive at the time, but I have had it for over 20 years. The company I used to work for just let people take them home. Mine is an older model, not as deep as yours and quite a bit taller. I am not sure what the actual model number is. I have misplaced most of my tips which is why they gave them away as the newer models used a different kind of and shorter tip. I just wished it had a way to display the temperature.

i have a question for you. so i am fairly new into understanding these soldering stations and i am a hobbyist mainly in rc car building but also make custom flashlights. i had a weller we1010na that i just returned because it struggled to solder the bigger stuff. i just bought a aixun t3a but havent recieved it yet. i solder some very big things 6 awg wire and big bullet connectors on rc car esc speed controllers. what would be the best soldering station you would recommend for plenty of power for someone doing big soldering stuff but also small pcb on flashlights if i want? is the t3a i bought going to cut it?
