PCB Heatbead for Home Etching by triffid_hunter, published Sep 7, 2011

I saw prusa’s excellent heated bed, but the dimension was too large for the blank stock I had available, and there were too many narrow traces for an easy home etch, so I designed a different one.
Dimensions are 200x200mm, hole centers are 190mm apart.
Design resistance is 0.95 ohms. Etch from 1oz (36um) copper to get this resistance.
Gives 150w from a 12v source, and consumes 12.5A.
I’ve had my bed up to 140°C before, and didn’t want to take it higher for fear of cracking my glass or damaging the FR4 PCB material.

Bill of Materials:
- 3mm LED (through-hole)
- 10mm length reed switch (through-hole)
- 470Ω ¼ watt carbon film resistor (the common ‘hobby sized’ through-hole)
- 12mm or 10mm battery retainer
- Coin cell battery to match retainer (10mm works well with a CR927 for example)
- Strong-ish magnet
