Abstract
Official abstract text for this publication.
An inspection method includes photographing a measurement target to acquire image data for each pixel of the measurement target, acquiring height data for each pixel of the measurement target, acquiring visibility data for each pixel of the measurement target, multiplying the acquired image data by at least one of the height data and the visibility data for each pixel to produce a result value, and setting a terminal area by using the produced result value. Thus, the terminal area may be accurately determined.
First claim
Opening claim text (preview).
What is claimed is: 1. A board inspection apparatus comprising: a stage transferring a board; a first illumination section illuminating a light for aligning the board onto an inspection target formed on the board; a projecting section projecting a grating pattern light for acquiring height data of the board onto the inspection target; a second illumination section illuminating a light for discriminating a terminal area of a component from a solder area that are formed on the…
