Questions tagged [copper]
The Element Cu known for its electrical and thermal conductivity, both of which are exploited in EE. THis material is typically what is used in PCB's for the traces and also modern CMOS processes have Cu layers in them due to it's superior conductivity. You also see copper in heat sinks to carry heat away from components.

Coils! Does the material used matter?
I've been making some coils with wires and I find out that sometimes they work and sometimes they don't work at all, the inside of those that don't work are some what more "silver-ish", more "metal-...

How do I determine the area of copper needed on a PCB to provide adequate heatsinking for a power SMD MOSFET?
I am planning to use the IRFR5305PBF Power MOSFET (http://www.irf.com/product-info/datasheets/data/irfr5305pbf.pdf) to switch on a load. I have determined that I need an external heatsink with Rthsa &...
