Inspection of electronics packages using the efficient perception technique

Inspection of electronics packages using the efficient perception technique When engineers choose and arrange proper lighting sources for an inspection system, many of them rely on their own experience or guesswork without any guidance of theories. This paper discusses the efficient perception technique, i.e. the TorranceSparrow model and its application to the selection and configuration of light emitting diode LED lighting sources for a package visual inspection system. Inspection of several typical package samples has been evaluated. The image changes of the sample packages are explained using the TorranceSparrow model. The experimental results with the actual gray level values of the images are compared. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Microelectronics International Emerald Publishing

Abstract

When engineers choose and arrange proper lighting sources for an inspection system, many of them rely on their own experience or guesswork without any guidance of theories. This paper discusses the efficient perception technique, i.e. the TorranceSparrow model and its application to the selection and configuration of light emitting diode LED lighting sources for a package visual inspection system. Inspection of several typical package samples has been evaluated. The image changes of the sample packages are explained using the TorranceSparrow model. The experimental results with the actual gray level values of the images are compared.
