| DIY hot plate for reflow soldering |

I got a nice purpose built digital hotplate for under $50 new shipped ($46) on ebay. It has an aluminum block and distributes heat evenly. Its made for preheating and reflow. Ive also been using two small bimetal thermometers which I bet you could duplicate for cheap, I thought they were ancient unobtainium parts but it turned out they are still made by a company in LA and cost around $50 each, way too expensive for a tiny thermometer. But they are very useful and also accurate. You could make your own, the key part is the bimetal spiral. If you can find a bimetal thermometer thats all metal you'll be good. It responds faster than the digital readout. Also if your area is well lighted you can see the solder melt clearly because no glass door. |
