Nowadays, with the rapid development of industry, electronic consumer products are increasingly popular, in the electronics industry, quality and precision are the core elements that constitute the concept of intelligent manufacturing. As a mobile phone screen glass phone manufacturers also put forward higher requirements for mobile phone cover glass in terms of improving quality, reducing costs, improving yield, etc., so it is necessary to ensure the technical realization of precision measurement.

With the progress of science and technology, in the background of the strong development of industry 4.0, the previous 2D vision has been far from meeting the needs of the current industry, in the continuous exploration and progress, 3D vision inspection application, the following small series of Lihe technology to uncover the mystery of "3D vision line confocal sensor" for you:

Nowadays, electronic products tend to be multi-functional, intelligent and miniaturized, from consumer electronics to industrial equipment, military weapon systems, etc., as long as there are electronic components such as integrated circuits, the electrical interconnection between them must use PCB. With the progress of information technology and the rapid development of industry, chip technology technology has been improved, high-density BGA, chip level packaging and organic laminate material as the substrate of multi-chip module packaging printed board has become a hot market, mainly due to its miniaturization, thin and light structural design, taking into account its heat resistance and heat dissipation, and can adapt to the needs of high frequency and high speed communication.

Surface roughness refers to the basic characteristics of the surface micro-profile. Surface roughness is one of the important indexes to evaluate product performance in the fields of machining, film preparation, micro and nano electromechanical system, optical precision machining and so on.

Film thickness tester is a common equipment coating detection tool, the use of magnetic thickness measurement method, can easily measure the thickness of non-magnetic coating on ferromagnetic materials, so the film thickness tester is sought after by many manufacturers.

3D measurement technology based on line laser is a new non-contact measurement method in recent years. It can measure the surface topography of 3D objects with large area and high resolution by means of high-speed laser scanning. Because of its fast, non-contact and high precision, it is widely used in industrial on-line measurement field.
