Abstract

Es un metodo de inspeccion utilizando una imagen en seccion vertical. Se adquieren varias imagenes en seccion horizontal, que se extienden a traves de un objeto de interes. Se define una region vertical de interes a partir de los datos, representando las imagenes en seccion horizontal. Se construye una imagen en seccion vertical en base a los datos de la imagen en seccion horizontal dentro de la region vertical de interes. Los datos de la imagen en seccion vertical pueden analizarse para detectar defectos. Ademas se proporciona un metodo para detectar defectos en una union BGA. El metodo incluye localizar un centro de la union. El metodo puede incluir ademas la medicion de varios diametros a traves del centro de la union y aplicar una regla para comparar los diametros medidos con un diametro esperado.
