In the electronics industry sensitive electronic components are manufactured in EPA areas, or those in other modules, so-called ESD (electronic sensitive devices), installed. The latter can z. B. also in the automotive or aircraft industry be the case, which is why EPA areas are also necessary in other industries. An EPA area may, for.
