Under normal circumstances , PCB manufacturers many products, mostly high-volume production , and the need to measure a variety of geometric elements, such as length, width, pitch and hole position degree. Therefore, efficient, fast, accurate measurement of the various elements of the PCB manufacturers have become the subject of most concern .
PCB ( printed circuit board that is ) is an important electronic component is the support of electronic components, electrical and electronic components provided by the connection . Almost all electronic products are required to support the PCB. As electronic products become more complex , the need for more and more parts , parts on the PCB line with increasingly intensive , PCB quality directly related to the function and performance of all kinds of electronic products. In order to ensure PCB quality , in the production process requires the use of a variety of advanced testing techniques were used to detect defects and failures to detect and repair .
Low traditional PCB geometric measurement tool intelligence, mostly artificial manipulation, resulting in low efficiency measurement , measurement errors have a greater accuracy , and therefore seek new measuring instrument is indeed imperative PCB industry . Image measuring instrument because of its non-contact measurement , measurement and high efficiency in the PCB industry will have a very significant measure upper hand. It is an optical lens, CCD image data to obtain geometric measurement of high precision instruments.
