Cooling Guide

This paper is a great introduction to the design considerations, mechanics, and basic equations needed to determine cooling requirements for an electronic system. Cooling is sometimes viewed as a “we will test it and see” strategy and this paper provides some analytical methods to gain confidence in a design without a high end finite element package and without a “wait and see” plan. This paper was authored by Comair Rotron.

TIN Commandments

This paper was authored my AMP Connectors and it provides a terrific guide for understanding how to use tin plated connectors. There are important design considerations that need to be given to any type of connection including mating pressure, current requirements, and signal integrity. This paper provides some manufacturing and long-term reliability guidelines for tin plated connectors.
