The lab power supply is very very nice, you can set up current limit, and voltage.
Also, both current and voltage settings have fine and coarse setting knobs.
That’s very handy for testing LEDs, since you would easily fry them if you would be setting just the voltage.
The unit has a main power switch on the back, and also a separate switch for each of the components (hot air, soldering iron, power supply). So they are completely independent. Not sure though if it is safe to run all of them continuously without overloading the power supply of the unit. Will check that.
One improvement that I would consider is replacing the unit fan with one a little bit more silent, or temperature controlled. It’s not too loud, but you can hear it.
It comes with only one solder tip, would be nice to have a few of them, but they are also cheap to get separately.
I’m thinking about one of these really hard. My Weller WES50 is not heating up like it should. I haven’t used it in about 10 years and it was working fine before. Just can’t get it hot enough for some reason and it’s not in lockout mode.
My tip is not corroded but is heat discolored. Also the Weller replacement tips are expensive. I might as well just buy a Chinese solder rework station and call it good.
That is what I have been looking at…but on ebay. Price difference between thm is only 10-20 bucks, but they look exactly the same. Are they just generic, re-branded units?
Some of them, I gather from various online reviews, have someone do minimal quality control for safety issues before shipping their product.
Often the comments I’ve seen say their purchased ones aren’t even remotely close to safe as sold.
Trace the wires and make sure what you hold is both properly grounded and properly switched, I think, is the overall message.
I always tend to follow the eevblog credo: “Don’t turn it on, take it apart”
That might be a lifesaver one day. I still have my new hotair (858d+) on the workbench, ground is not good as the painted metall case isn’t connected and I will upgrade it to a dualwire switch. One thing that is really messy is, that it has a male connector with live 230v for the hotair gun on the front. What the were they thinking.
So allways check your stuff and only buy it, when you know what your doing and how to repair those things. Otherwise I would only recommend high quality brand stuff.
I love their 8786D hot air station I got. It's a quality made unit and grounded properly. The 907A soldering iron is a pencil tip and only good for very small stuff.
yes, quite easy, I think you could easily set it with 0.03V accuracy, with external voltmeter.
I just checked with 2 multimeters, the voltmeter built into the rework station seems to be off by cca 0.05 to 0.15V (it shows lesser voltage than actual), difficult to say which one of them is the most accurate one.
I wonder if there is a way to calibrate the voltage meter in Yihua, I was planing anyway to get a stabilized reference voltage source for calibrating my meters.
AFAIK Yihua itself is kind of a clone of more expensive EU/US stations, but they seem to be decent quality. However there are then clones of Yihua, and then there could be much lost in translation there. The place where I bought it (baumtronics) is supposed to be authorised EU reseller, and they test before shipping.
I’d never spend more than 150-200€ on this machine, because it’s just a hobby, so for me it’s either this, or nothing
