In order to ensure and achieve an efficient and smooth printed circuit boards (PCB) manufacturing process the textile quality control provider Loepfe Brothers Ltd., Wetzikon/Switzerland, developed a new optical sensor: Falcon-i.
A fully integrated PCB manufacturer can control the entire manufacturing process. One of the world’s largest manufacturer of such boards and other technical glass fabrics, operating several plants in China and Taiwan, occasionally experienced tiniest unevenness on the surface of its PCB boards. Particular defects originated from exactly that woven glass fabric, eventually caused by minute filamentation of the yarn and slightest fluff accumulation during the weaving process. Falcon-i even detects the tiniest yarn irregularities. It offers extensive sensitivity levels, allowing customers to fine-tune the ratio of machine stoppages caused by necessary quality control stops. Any manufacturer of demanding technical fabrics and composite textiles used in applications such as PCB manufacturing, automotive, architecture, filtration, aeronautics, medical and carbon industry can highly benefit from this type of versatile quality monitoring sensor. The implementation of Falco-i optical yarn defect sensors in the quality control of any running yarn throughout the manufacturing process of fabrics is simple and easy.
