YIHUA 939D+ Digital Soldering Station, 75 Watt Equivalent with Temperature Control, °C/°F Display. ESD safe for Electronics. Aluminum Panel (Resists Burn). Solder Tips, Lead-free Solder & Extras

This a fantastic little station. It get hot and it gets hotter and more than enough heat to power through even the dirtiest motherboards. This thing had the helping hands and the roller with tip cleaner all set up pretty well for easy use. Comes with solder and extra tips. No flux oddly but with the heat this thing puts out and a clean tip you don’t often need it . Only complaint I have is the brightness of the light, it’s laughable but the rest of the station is serious business.

I typically use the main brand soldering gears for many years, mainly for debugging, bring up verification. I never heard of Yihua before, no idea of its quality or performance. I did some research on Yihua before I give it a try, seems they know what they are doing. The initial test was using this tool to work on 0402 parts and some MOSFETs, I really like these four buttons to select desired temp quickly, that's so handy, easily to work on tiny resistors then larger parts. The soldering tips are quite good, easy to clean and working with 0.3mm soldering wire. This time, I don't need the 110W power but I know it is ready there whenever I need it. I am impressed of its performance vs price range, give it a shut and it is good.

I bought this to replace my cheap Weller soldering station that I bought in April 2024. Weller doesn’t make replacement tips for that station so I decided to replace that with this Yihua soldering station that is a large upgrade, since I had good luck with the Yihua rework station I bought previously. It heats up very quickly and gets plenty hot. The leadfree solder that comes with the station is pretty decent. I really like the brass cleaning coils. I find they work way better than the sponge. The tips are the only thing I don’t really like. They don’t heat very evenly so I end up turning the station all the way up when using leadfree solder. Fortunately, the tips used in this station are very common so I will probably end up buying some better ones. The iron's cable could use to be just a little longer, but that's no big deal. This station is absolutely worth the $50. I highly recommend it.

Highly recommended for the person who only uses this a few times a year or is new to soldering and doesn’t mind seeing this as a starter unit. I’m a bit bias towards my old school weller station. There’s no need for a display on these things but the addition of one doesn’t take away from it. Temp seems to regulate well. I have 10+ hours on this unit now and overall enjoy it. It’s a great basement lab tool. Heats up very quickly. The tips are the only disappointment. The smallest tip isn’t that small but it’s too pointy(doesn’t transfer heat well), and most of the others are too blunt for PCB work. Of the three tips I’ve used, none of them have consistent heat output. You'll always have some kind of hot spot even on the high dollar units and tips are standard so you can buy the nicer pieces when or if you need them. Generally my only complaint is the consumables, the unit itself is very solid.

In case anyone else has trouble getting the Auto Power Off function to work, here is what I learned. First, read the instructions...just as is stated, the Sleep Function must be set also. I couldn't figure out why mine was not auto powering off until contacting the seller. They offered a quick and thorough reply which explained what I wrote above. The current models as of this writing (6/2/22) will blink 3 dashes in the display indicating the Auto Power Off. Other than that minor self inflicted snafu, this a very impressive soldering station, and at a good price. I was looking for a replacement for my Xytronic 137ESD Digital station, which I have had for a very long time. It served me well through thick and thin and I hated that it finally gave up the ghost. Unfortunately, they are no longer available, so I started searching for a comparable replacement. Low and behold I kept seeing this Yihua station, read several reviews and decided to take a chance. So far, glad I did. Longevity is yet to be determined, but I am amazed at the quality and features. This heats up to the desired temperature so fast, it's not even funny. And it remains steady. I like the 3 temperature presets. The display is crystal clear and easy to read. The iron fits my hand well and is nicely balanced. I'll sum up by saying the first unit I got had temperature stability issues and also threw an S-E error code, which is not good, but the exchange process was so painless and quick I really can't fault the seller. If you're on the fence deciding if this is the one. I would highly recommend giving it a try. Return is easy if you don't like it for any reason.

Two disclaimers: 1. I've only had this for two weeks, so can't speak to long-term robustness. However, I have used it for several hours per day during that time. 2. I have a thermocouple setup that I can use to measure the temperature accuracy and calibrate the unit. However, I haven't as yet calibrated the thermocouple system, so have not done so. Since the soldering station has worked so well from the first time I used it, I haven't bothered. I have been electrical & electronic soldering, some limited plumbing soldering, and, lately, some plastic welding (using an iron) thrown in for good measure. I've used irons, guns, and an old Weller analog station, but this is my first use of an up-to-date digital station. I worked for an aerospace firm that even gave me a course in it (though it wasn't really part of my job as an engineer; it was primarily for our technician colleagues). Even with all this experience and practice, I've never been very good at it. Usually, I can make copper stick together and get a zero reading on a multimeter, but it usually takes way too long and looks like crap. Heaven forbid that any customer ever attempted to fly anything that was held together with my soldering. Well, no longer. This station has made me a pro (though some of my technician colleagues may yet disagree). What it's been used for the past couple of weeks is the worst of my soldering jobs: connecting those waterproof LED lighting strips where you have to cut away the silicon gel coating to get to the copper pad (which itself seems akin to brain surgery) and then solder connecting wires to that. Of course, irons and guns have no adjustments, and, for whatever reason, I could never dial-in the old analog station to make a clean job of that. Miraculously, this station has made that a breeze. After a few days of trial and error and getting the station dialed in plus a few "technique adjustments", I was so pleased I ordered a second one for a remote workshop. Secondary to function, especially useful is the feature that you can secure the iron holder to the top of the power supply or remove it to place in a more convenient position. Since my work spaces are small, with constantly changing configurations and very limited storage, I made an aluminum stand for my old Weller that implemented this very feature; however, my MIG aluminum welding skill is even worse than my soldering skill, so, though it was functional (well, after a couple of "accessory pieces" had broken off), it was a complete piece of junk- cosmetically, a DIY abortion that no one should have to gaze upon. It is really nice to see this capability incorporated into an off-the-shelf product. Additionally, most of their manuals are online, but the manual for this one isn't (or wasn't; I think it's a brand new product). Since I now have two of these, and find it hard enough to keep up with one hard-copy manual, I contacted their customer support to get an electronic copy. They were prompt, courteous, and fulfilled all expectations in that regard as well, and the manual is securely stashed away on several different computers. I would highly recommend this product.

This is a great non-production soldering station for all electronic enthusiasts and even repair needs. I've owne them all over the years and this is the best deal I have found, so far for a light duty soldering station. It does everything well that a soldering station should do. It heats up very quickly to the selected temperature and maintains it very well as you solder. Of course it's not for heavy duty wiring and heat sucking soldering jobs. You need a higher wattage iron for that kind of stuff. But, it is perfect for PCB and delicate soldering use. Grounded tip protects CMOS & static-sensitive devices. Soft silicone cord is easy to handle - you don't have to fight with it. Comfortable & Cool lightweight cushioned iron, too. Nice selection of tip for various types of jobs including knife type included. My only complaint is that the blue LED display is too dim for viewing in a brightly lit area, like where you solder! Otherwise, it really puts Weller and others to shame at this pricepoint of $50-60. Highly recommended.

Awesome product - super easy to use and the memory function is awesome when trying to get the right temp on complex projects! Heats up extremely fast and haven’t had any trouble with cleaning. Tips are great for a wide variety of applications in my experience and am loving my DIY lifestyle. The stand is also well built and stable enough to have saved my carpet more than once
