Allow for lower temp settings with MHP50

atuleu

I plan to use the MHP50 for reflow / rework of low temp paste (Sn42/Bi57/Ag1). Those solder paste have very low welding temperature (recommended profile : welding temp 165°C).

However the the MHP50 doesn't allow
* to set a fixed temperature below 100°C
* to set a rise temp below 130°C (required by manufacturer 90°C)
* to set a keep temp below 150°C (required by manufacturer 130°C)
* to set a welding temp below 230°C (required by manufacturer 165°C)

I tried to hardcode those values through the CONFIG.TXT file when the MHP50 is plugged to a computer, however it resets to the default one if it falls out of the hardcoded boundaries.

I think an update to the firmware that would allow for much lower temperature limit will be a great addition to this product:
* Allowed fixed temperature range: 80-350°C
* Allowed RiseTemp: 80-170°C
* Allowed KeepTemp: 110-170°C
* Allowed WeldingTemp: 150-260°C

Thank you for your help.

Oh also, the time duration for the three zones, especially the upper limit is also very restrictive, ...

Thank you!
Thank you very much, MHP50 will have a major update.

Thank you very much for your suggestion, we will open a lower settable temperature for reflow soldering in the next version of firmware.

I to would like this option,  again I use low melting point solder paste and require the low temperature for the reflow profile.

Could you update on when this newer firmware will be released.

I would like this option also,  when will the firmware be available/released?

We may update this feature in the next version, but the timeline is not yet clear.

I also need lower temperature settings. Please enable this option as soon as possible. Thank you for your consideration.

Thanks for the suggestions!

Please, add this feature as soon as possible. This is such a basic option that should have been included in the first release already. The temperature of 230 ˚C is simply too high for the reflow zone. In my opinion, all the temperature settings shouldn't have any restrictions (only to the hot plate limits).

Thank you!

Oh also, the time duration for the three zones, especially the upper limit is also very restrictive, please extend the limits for these too if possible.

Thank you very much!
