Solder joint integrity may be compromised through mechanical shock,
particularity in portable electronics using area array devices with
solder balls for interconnections.
The concept for the introduction of an electrostatic discharge (ESD)
control system is expanded here to cover the most important topic at
the moment: static control requirements for machines and production
plants.
The idea of monitoring manufacturing processes using statistical methods goes back to the 1920s when Walter A. Shewhart, an American physicist, engineer and statistician, was engaged by the Western Electric Company in Chicago to find a way to produce their products with a certain quality level.
