日本日立制作所最近研制成功了可以高精度、自动地检测印刷电路板图形断线、短路、开路、缺陷等微细症状的印制板图形检测装置MP1100,并已在市场上出售。 该装置利用在印制板的原材料中产生的荧光,由于这种荧光不受基片表面形状变化(污染、变色、伤痕等)的影响,从而可以检测出最小10微米的图形缺陷。与以前利用反射光检测的装置相比,缺陷检测率为100％,误辨率为十分之一,大幅度地提高了可靠性。
Japan’s Hitachi has recently succeeded in developing MP1100, a printed circuit board inspection system that can detect fine patterns such as breakage, short circuit, open circuit, and defect in printed circuit boards with high accuracy and accuracy, and is on the market. This device uses the fluorescence generated in the raw material of the printed board. Since this fluorescence is not affected by changes in the shape of the surface of the substrate (contamination, discoloration, scratches, etc.), a pattern defect of a minimum of 10 μm can be detected. Compared with the previous devices that use the reflected light detection, the defect detection rate is 100% and the error resolution ratio is one tenth, which greatly improves the reliability.
