PCB Hotplate Continued

The hot plating continues! And with the boards actually in hand, I can compare my estimates to some real world measurements. In the end, I made both FR4 and aluminum heaters. These heaters ended up having slightly different properties. Oddly, the aluminum PCB has a higher resistance (4 ohms) than the copper pcb, 2.9 ohms).…

PCB Hotplate Controller

The PCB heater for the hotplate obviously needs to be driven by something. I could have put more circuits on the heater board itself, but separating them has some advantages: My goal for the hotplate is to keep it simple. I decided that I really probably need one profile at most, and a manual-temperature mode.…

PCB Hot Plate State of the Art

I have started seeing a whole bunch of PCB hot plate builds, of varying success. I kind of want one now, since they seem very practical for one-off small PCBs, and most off the shelf solutions are quite large. However, I also want to improve on the state of the art of PCB heaters. These…
