Electronic board inspecting method, involves subdividing reflected images into analysis zone, allocating reflected ray values to analysis zone, realizing signature of zone, and comparing signature of zone to reference signature

摘要

#CMT# #/CMT# The method involves exposing an electronic board (8) to rays having different wavelengths, and establishing reflected images (4) of the board for successive rays. The images are subdivided into an analysis zone (5) by a sensor (3), and reflected ray values are allocated to the analysis zone. A signature of the zone is realized by a controlling and processing unit (14). The signature is compared to a reference signature of a printed circuit by the controlling and processing unit. #CMT# : #/CMT# An independent claim is also included for an electronic board inspecting device. #CMT#USE : #/CMT# Method for inspecting an electronic board. #CMT#ADVANTAGE : #/CMT# The method enables inspection of the electronic board in an effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of an electronic board inspecting device.'(Drawing includes non-English language text)' 1 : Camera 3 : Sensor 4 : Reflected images 5 : Analysis zone 8 : Electronic board 14 : Controlling and processing unit.
