Year ago I also want purchased Imdes Jumbo. The main reason was save my time and not building it 2nd suitable size for large pcb panels and last reason was price. Once I saw the quality of product inside I completely decline the idea to invest such many to Jumbo.. Once I have 20k I will definitely purchasing ascon or IBL oven to save my time.
So main jumbo problems:
1) Slow cycle time 25+min. S pear day you can soldered just 10 panels or so..
2) Liquid galden drops on PCB after cycle.
3) poor quality
4) price / quality
5) passive cooling system
So I build for myself vapor phase soldering unit for fraction of cost.
If you wanna follow my progress on the project I am on Instagram @vapor_phase_soldering
I designed simple power unit compatible with Arduino socket so it can be connect to stmmucleo discover arduino kits.
Originally it was design for stm32f7508 discovery with nice LCD and touch panel. Power unit is very simple and contain only necessary component to run heating element, measure temperature (k type thermocouple using max chip ) beeper for sound signalization, and some extra power channels for FAN, water coiling and so on
I can make some video about progress, and how it works, talk about weak spots and so on.
Also I can provide power unit compatible with arduino socket or complete set with smt kit and current version of SW.
About my SW:
- It has 3 custom profile.
- Each profile is dynamic so if you put inside large pcb with higher thermal mass it automatically correct for it.
- Profile recovery after shutdown.
- end cycle alarm - ready for next load.
- Automatic profile jump to current temperature.
