Holistic approach in designing reliable electronics board by considering thermal/heat management

Designing an electronic system for simple prototyping is different from designing electronic system of production grade. A production grade electronic system design needs lot more effort in terms of making the system reliable, rugged and withstand harsh weather conditions and meet some safety standards and approvals. Basically the system should last longer when it is operated at its full specified capacity and conditions.
There are so many factors to consider when designing production grade electronic system. One of the important design consideration is managing heat produced by components and also ambient temperature conditions impacting the operating of system. In electrical and electronic systems every electrical and electronics components conduct electricity that means electrons flow through it. When electron flows through any material they produce heat.That heat can be very minimal or it can rise to very high temperature. In today’s digital systems there are both signal handling electronics and power handling electronics. Most of the power handling electronics produce heat whereas signal handling electronics normally doesn’t produce that much heat, where you need to really bother about.However today’s high performance processors basically handle digital-computing and signal-pro...
