SOLDERING INSPECTION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To reliably decide whether soldering is acceptable or not. SOLUTION: An image pickup unit 8 picks up the image of a specified region on a printed board 2 including an electrode to be soldered. A data processor 6 makes smooth the brightness at respective parts of an image being picked up by the image pickup unit 8 at an image processing section 61 thereof and emphasizes the brightness contrast for a smoothed image. A decision is then made whether a soldered state is acceptable or not based on an image subjected to brightness contrast emphasis.
