INSPECTION OF SOLDERED PART OF MOUNTED COMPONENT

摘要

PURPOSE:To achieve a higher inspection accuracy and speed eliminating manual setting by defining a soldered area automatically to set an inspection area with this area as reference. CONSTITUTION:A component 2 is arranged on a substrate 1 and coordinates are computed with a coordinate computing section 12 based on a three- dimensional data from a sensor section 11 to set a contour line with a contour line detecting section 14. Then, a tracking line is set with a soldered area determining section 15 to identify both ends of a soldered part 3 while a border of the soldered part 3 is obtained to determine a soldered area 4. With this soldered area 4 as reference, an inspection point is set with an inspection point setting section 16 to judge the quality by a sectional area and height of the soldered part 3 with a quality judging section 17 from a data at each inspection point thereby eliminating the need for specifying the soldered area 4 manually.
