Custom-made reflow hot plate - Final assembly

Electronics

In this video, I show you the final assembly of my custom-made reflow hot plate. I fixed some cables and connections, fixed the heating plate and assembled everything on a plywood sheet. So now I have a fixed, permanent assembly that I can pick up any time and solder my SMD circuit boards.

The last assembly was a huge mess because of the following things:

the wires were all over the place and it was difficult to use the device
the heating surface was just sitting on the ceramic insulators, it was not fixed to anything
the heating surface was not grounded
The 3d-printed assembly that held the mica heater became very soft and slightly deformed by the end of the reflow process

This final assembly has corrections for all the above issues. I fixed the whole system on a plywood sheet, so everything is stable, nothing gets soft or warped during the reflow process and it is effortless to handle the device (storage…etc.)
