Application of photoelectric switch in PCB board

PCB is called printed circuit board. Common electronic devices such as mobile phones and automobile electronic control systems. Computers, tablets, electronic communications, etc. are all needed. It is the main supporting combination part for the connection of electronic and electrical devices. In order to ensure the quality of PCB, various tests must be carried out during the production process. With the development of science and technology and the improvement of technical requirements, automatic detection of machines has now been realized, and photoelectric switches are equivalent to the eyes of machinery and equipment.

When testing the PCB circuit board, the stability of the photoelectric switch should be considered. The effect of the material and color of the product detection on the photoelectric switch, the light reflection ability will also be different. For example, lighter-colored objects are easier to detect than darker objects, and light-colored objects are easier to detect than sandy objects. The general diffuse reflection photoelectric switch has a blind area of ​​about 1mm. In this area, many objects cannot be detected stably. Dark objects and sandy objects will be more difficult to detect. In response to a large number of industry and technological development needs, okplazas.com independently developed a photoelectric switch without blind spots, which is more reliable than other photoelectric switches for detecting objects.
