Excellent product I highly recommend! Very well built, works like a charm, has more features than a fully priced Hakko. Many people complain about a few design flaws but imho, most of these are not justified (or just overzealous). Here are a few examples: 1. The heatsink is right above a hot track. While true, I don't think it matters at all. Current doesn't flow to the heatsink because of the pcb mask. Some say in case of overvoltage (like 1kV), it may happen. But such a power surge would blow the fuse anyway. Now what if the pcb mask wears out? Well, the heatsink will just be at a high potential, which is not a problem since it doesn't connect to anything. And what if it ever does? Well, shorted to earth, the house differential will activate, shorted to neutral, the fuse will blow. So I don't think it's a big concern. Not a concern of mine at least. 2. The power connector is soldered directly to the pcb instead of using wires. This would be a problem if the pcb was physically attached to the case, as forcing power chords in and out would break the solder connection. But that can't happen here. The pcb is only held by the connector and can freely slide inside the case. So now amount of play with the power chord/plug would break it. The pcb is not screwed to the case for that exact reason. 3. The metal case is not grounded. This would be a major concern if any hot wire could touch the case from the inside. But there are no floating parts in it. As said, the power connector is soldered to the pcb and I can't see how the case could receive any voltage at all. Note, the fact the aluminum is anodized means nothing to me as it still carry charges, and screws make the connection. But in my country, regulations say any metal case must be grounded, plus I like peace of mind, so I just drilled a hole in the case, fit it with a screw, and put a wire from here to the ground. Problem solved.

BG251220186 Great write up.

Question for you. is the iron handle and/or tip grounded through the PCB even if the chassis isn't grounded? I can see a benefit to not having the tip grounded if you needed to work on a live circuit. I've been thinking about adding a switch inline to ground that would remove the tip from the earth ground path. maybe a key switch, so that it can't be accidentally removed from ground, hmm.

Lastly, I know about the heatsink over the trace on the 72W power supply board. I think that this unit is supposed to have the 108W power supply board. is the problem with trace/soldermask/heatsink overlap present on the 108W board also? I've tried searching online for the answer but I have not found any reviews or tear down articles or videos specifically for the 108W board units.

TIA
