Heating a Nichrome Wire with Math
I am going to be working with nichrome wire; so, I thought I would explore some of it’s properties. This is the result. Continue reading
PCB Thermal Resistance – Some Unexpected Results
When designing for an IC that uses the PCB as a heat sink, the datasheet usually only gives a single layout example – if that. But, what if you can’t implement your design exactly like the example? What are the relative effects of various compromises? It turns out that my intuition for which factors were most important was quite wrong. Continue reading
