Heat and temperature effects

See index of topics below

Heating of electronics should be taken very seriously. Bad designs have started their fair share of fires. Remember there's people who'll have to clean up your mistakes. Do your best not to ruin their day!

This is a page ties together a lot of information on temperature measurements, heating analysis, etc.

Heat and temperature are two enemies of electronics, as evidenced by many of the pictures in the Microwave Mortuary. But heat is a love/hate relationship in microwaves, as you know microwaves are used for heating applications. There are microwave tubes that require heat to operate, and there are oscillators that have to be oven controlled to stabilize. Heat and temperature are important parts of microwave engineering.
