Miniware MHP50

We all know about the mhp30 (don't we ?). Miniware has now the MHP50, It seems fairly recent (one month old ?).

What picked up my interest is that, contrary to the mhp30, the mhp50 seems to be able to follow a reflow profile.

I've never been interested in the mhp30 because it's really small and was only "set temperature". I know people use it to solder, desolder, and repair nevertheless. I guess they put/remove the pcb 'wisely' so as to more or less reproduce a typical profile, using their eyes as a feedback mechanism. Or .. ?

Anyway, I think the mhp50 deserves an eevblog topic. It's bigger (50mm versus 30 as the name implies) and more expensive, but not much.

There's not a lot of information on the web currently. Miniware has an official product video about it on youtube. I know miniware has an official eevblog account.

That's not completely true. With the latest release 2.22 of IronOS (https://github.com/Ralim/IronOS/releases/tag/v2.22) you can define a reflow profile. Unfortunately two drawbacks:
1) The company has changed the HW from STM32 to a GD32 processor, release 2.22 will not work with the GD32
2) Running the profile is limited by the heating power of the MHP30

Today I received my MHP50. Decent quality, nice color display, needs a powerful power supply (100W) ....

Oh, I didn't know. It's fairly recent though, and not from the official firmware. But good to know ! Though for a new buyer, the 50 seems more interesting.

Great ! Please share your thoughts after a while. Especially as you previously had a mhp30 to compare with.

The aluminum and brass tops cost the same from that seller ($93).
Brass takes a bit longer to heat up, but the temperature would be a bit more stable. I don't think it would matter much for real world use.

Build quality is excellent, but I need a new power supply capable of running it!
