This article is a selection case of a user choosing a laboratory coater. The user wants to scrape PCB ink on the PET carrier film. The thickness of the PET carrier film is about 10um, but it is relatively soft and difficult to keep flat. membrane. In addition, the thickness of the coating film is 18um-20um after drying, and the solid content is about 70%.
According to the user's substrate situation, just choose a laboratory coater with vacuum adsorption function to meet the customer's needs. In addition, according to the user's coating film thickness and solid content parameters, it is estimated that the required wet film thickness ranges from 22.9 to 32 microns. According to the overall situation, the technical engineer of NBCHAO suggested the following set of experimental coating equipment selection list.
