Elektronikfertigung bei SMA

Elektronik-Platinen sind das "Hirn" jedes Wechselrichters. Bestückt mit tausenden, teils winzig kleinen Bauteilen sorgen sie für die Energieumwandlung, übernehmen aber auch Kontroll- und Steuerungsfunktionen. Dieser Film zeigt den Herstellungsprozess der Platinen.

Esta pelicula ilustra el proceso de fabricacion,verificacion,teste de las tarjetas electronicas de los inversores.
