AUTOMOTIVE

As automotive electronic applications continue to grow in number and complexity the demands made upon them for increased performance and reliability present many design challenges. By nature, the environmental conditions under which these units must work are very harsh. Temperatures under the

bonnet are increasing and geographical locations can also produce extremes in the other direction - these extreme thermal cycles induce stress and the possibility of component failure. To add to it there is mechanical stress as a direct result of vibration derived from the engine and road conditions.
