Custom reflow hot plate - Demo and coding

In this video I show you the assembled system with a much better heating plate than in the previous videos. I managed to obtain a nice ceramic heating plate which has much better characteristics (power and surface area) than the heater I used previously. After going through the main parts of the assembled system, I solder a simple PCB to demonstrate that the system works and after this demonstration I explain the source code line by line.

Arduino Nano

1.8” TFT LCD

Rotary encoder

MAX6675 thermocouple module

230 V AC to 5 V DC 600 mA PSU

Mica heater

40 mm fan

1.5 mm aluminium plate

Paper clips

Get this PCB or other PCBs designed by me from PCBWay!

Second PCB

This is the second assembled PCB. Unlike for the previous PCB, here I directly soldered the LCD and the rotary encoder module to the PCB. I also added an acrylic plate over the high voltage parts and under the whole PCB.

Another perspective

12x12 cm ceramic heating plate

I used this ceramic plate to heat the PCB. This same heater can be found in certain BGA reflow stations.
