When electronic vehicle systems fail, itís often not the fault of microcontrollers, memories or integrated circuits. By watching for some of the following problems, designers can often boost reliability of end products, especially in automobiles.
Minimize connections. Thereís a high correlation between reliability and the number of electrical connections made at an assembly plant. A dashboard with ten connections, for example, is likely to be more reliable than one with 50 connections.
Make sure wires donít rub against sharp pieces of metal.†
Ensure connections go together with an audible snap. If assemblers hear the snap, they know itís connected.
Design in reliability at the beginning. Usually, if a car starts out reliable in its first model year, it stays that way.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the worldís biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Samís Club members-only wholesale outlets, and on walmart.com.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
