Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 フラックス部に発生した輝点の誤検知を防止 し、ピンの半田不良部とそれ以外のフラックス部とに同 一の明るさの輝点が発生することによるS/Nの悪化を 防止するとともに、照明とカメラを最少限にし、コスト ダウンを可能にすること。 【解決手段】 プリント基板3に実装されている多数の ピン31を備えた表面実装部品の各ピン31の半田付け 部の長手方向に対して交差する方向に照明を照射する2 個の照明装置11、12と、前記プリント基板3の上方 に配設され、照明が照射された表面実装部品の各ピンの 半田付け部の画像を撮像するカメラ2と、該カメラ2に 接続され出力される画像データに基づき、前記表面実装 部品のプリント基板3の各ピン31の半田付け部32の 画像の明るさにより、半田付け不良を判別する演算制御 装置5とから成るプリント基板半田不良検査装置。 PROBLEM TO BE SOLVED: To prevent erroneous detection of a luminescent spot generated in a flux part, and to generate a luminescent spot having the same brightness in a defective solder part of a pin and other flux parts. To prevent the deterioration of N and minimize the number of lights and cameras to enable cost reduction. SOLUTION: Illumination is performed in a direction intersecting a longitudinal direction of a soldering portion of each pin 31 of a surface mount component having a large number of pins 31 mounted on a printed board 3. Lighting devices 11 and 12, a camera 2 disposed above the printed circuit board 3, and connected to the camera 2 for capturing an image of a soldered portion of each pin of a surface-mounted component to which illumination is applied. A printed circuit board soldering defect inspection comprising an arithmetic and control unit 5 for determining a soldering defect based on the brightness of the image of the soldering part 32 of each pin 31 of the surface mounted component printed circuit board 3 based on the output image data. apparatus.
