Detailed introduction of thin film coating online thickness gauge

Precision measurement and control thin film coating thickness measurement equipment can replace manual visual online inspection

Introduction: The detection of film coating thickness will be helpful to effectively control the thickness uniformity of each layer of the film. However, if you want to accurately measure the thickness of each coating for multi-layer films, you need to have a very large amount of equipment on the corresponding thickness detection equipment. The investment will increase as the number of film layers increases, which will bring a greater economic burden to the enterprise. A more economical way is to test the coating thickness of some expensive coating materials, and at the same time strengthen the test of the overall thickness of the film to effectively control the thickness uniformity of other layers of materials.

For film thickness measurement, Wuxi Jingpu Measurement and Control has continued to increase investment in research and development and is committed to technological innovation. Precision Measurement and Control Thin Film Coating Thickness Measurement Equipment Precision Measurement and Control Thin Film Coating Online Thickness Gauge The thickness gauge specially developed for thin films can effectively measure the thickness of single or multi-layer transparent films. It has extremely high precision and is widely used, especially suitable for thickness measurement of transparent multi-layer objects with thickness requirements reaching the nanometer level.

Types of coatings: There are usually 3 types of coatings:

1. Water-based coating: The concentration of the solution is between 10% and 60%.

2. Oil-based coating: The solvent is an organic solution, which is similar to the application of water-based coating, but please note that it contains certain dangerous goods components.

3． Extrusion and hot melt coating: The melt is applied to the substrate. The types of coating heads include heated die, heated tank and immersion tank.
