Hello Everyone
I know that it has been a while again. My apologies for the delayed post. There were some glitches in the firmware which I’ve discovered and I had to resolve these over the past month and a bit. I have also created a separate firmware package for the Arduino MEGA. There’s more progam space available so I could add some more features in the running cycle of the device. All of this have now been finalized.
Over and above resolving the glitches, I’ve experimented with my reflow curve and have finalized a curve that reflows the solder very nicely. I’ve created a little video for you guys that shows the assembly process of a unit, not using the hysteresis functionality vs. using the hysteresis functionality, the Arduino UNO firmware, the Arduino MEGA firmware and the actual reflow process in action.
Description: Starting Time: End Time:
****************************************************************************
Mounting of components – 00:00 – 01:25
No hysteresis vs. hysteresis – 01:25 – 02:07
UNO Version of firmware – 02:07 – 02:04
MEGA Version of firmware – 02:40 – 03:14
Reflow process in action – 03:14 – 03:42
I have also been busy finalizing the first 10 units and tested each and every one of these. All of them are working nicely. Then I went ahead and finalized the packaging, packaging went through a few phases but I finalized now on one and received the packaging today. But first some pictures of how the process progressed:
Glitches being resolved 🙂
Initial batch of units finalized
Filming of the reflow process. Needed to get as much light into the oven as possible
How the final product will look – oooOOOoooOOOoOoo (Using the wife’s camara – that’s why the photo just pops 😉 )
Prepping units to be packaged – very exciting 😛
What comes in the box – Reflow Master Shield, Type K thermocouple and some stickers
Everything packaged – Now to finalize my crowd funding campaign. Be sure to check in here for updates as to the launch date 🙂 and feel free to drop me a comment should you have any questions.

hi thank you for charing do you think i can use your code for 1200ºC and stages of hours ?
Hello Guilherme
Absolutely, you will just have to make some changes to the code to be able to do this.
The code is available from my Github page. Regards
Hello Guilherme
Here is the link to the firmware if you want to make changes to it to suit your application: https://github.com/PaladinEnabling-Technologies/Reflow-Master-Shield
Thanks for the help, I think I will use max31855 as sensor reader to get more range and also because of the higher temperature I’ll be sensing that seems to give feed backs of around 12v with your amplifier if read the datasheet correctly I probably will come back some more questions as I’m new to these world. thanks again
but as a model of the screen?
GLCD – WINSTAR – WDG0151-TMI-VN00 but any similar GLCD will work. That being said you might have to play in the library with the pin assignments
