Beta reflow V2 controller

Postby Pedro147 » Mon Jun 01, 2020 5:50 am

Hi guys. Not sure how well this forum is patronised these days but I figured that it was worth a try. I have the Beta reflow V2 oven controller that I successfully used for PCB reflowing some years back. I made many homemade drone flight control boards with it and was reasonably happy with it's performance See here viewtopic.php?f=11&t=250 I have moved on from that hobby to learning to fix Macbook laptop computers. A steep learning curve at my age for sure. I need to ultrasonically clean the logic boards after all the soldering repairs are done and then dry the boards in an oven at a 120°C stable temperature for about 15 min to remove the detergent / ionised water cleaning solution, particularly from under the BGA chips on the logic board. I am wondering if I can modify one of the temperature profiles to do this please ? I have totally forgotten how to use the oven controller and have also moved on from Windows 7 that I was using back then to Windows 10. From memory the temperature control file was an .ini file ? so I suppose that is what needs to be edited. Any help or advice would be greatly appreciated. I would approach the controller company but they are not very forthcoming with any help after they take your money. Typical in this day and age I have found. Thanks in advance if anyone reads this and can help

Thanks again David, I downloaded this last time I asked for help here but I don't think that I got it to work. Must not have been trying hard enough so I'll give it another try.

So do I just edit the ini file to hold a steady temperature with a quite fast ramp up and then down when my preferred time period is up do I ? The other problem I see is that your GUI only goes up to 380 seconds whereas I need a total heating time of around 15 minutes. Is there any way around this and can I only use three stages of heating as in preheat (a fast ramp up to temp) soak (my 125 degrees C drying temperature) and dwell (which will be my ramp down time) Will it still work if I do this, assuming that the 15 mins of heating time I require can be achieved by modifying the GUI somehow ? Thanks for your time too, any help would be greatly appreciated as usual )

Yes, that's pretty much it. You can control:

  • phttemp - pre-heat temperature set point
  • phttime - time in pre-heat
  • phtpwr - amount of power sent to oven heaters during pre-heat
  • soaktemp - soak temperature set point
  • soaktime = time in soak
  • soakpwr = amount of power sent to the oven heaters during soak
  • reflowtemp - reflow temperature set point
  • reflowtime - time in reflow
  • reflowpwr- amount of power sent to the oven heaters during reflow
  • dwelltemp - dwell temperature set point
  • dwelltime - time in dwell
  • dwellpwr - amount of power sent to the oven heaters during dwell

Sorry to be a real PITA but you caught me mid edit. You are too fast for me David :)

Is there any way around this and can I only use three stages of heating as in preheat (a fast ramp up to temp) soak (my 125 degrees C drying temperature) and dwell (which will be my ramp down time) Will it still work if I do this, assuming that the 15 mins of heating time I require can be achieved by modifying the GUI somehow ?

Where did you get that number from? Have you tried editing the *.ini file?

Oh sorry David no I was just going on the screen shots so I assume that the time period adjusts according to the figures used in the ini file.

Sorry about that, I didn't even think of that possibility. I am really not that smart :) and once again I appreciate all your work and spending time answering my questions.

No problem.

As you can see, the time line in the control panel will grow or shrink depending on the values held in the *.ini file.
