Technical application of high-precision thick film screen printing technology in CGM dynamic blood glucose monitor The CGM dynamic glucose monitor is an advanced diabetes management tool that monitors blood glucose changes in the next 7 to 14 days by implanting tiny sensors under the skin. The sensor is the highest barrier and core component of the CGM system. It is composed of a metal electrode, an inner layer, an enzyme layer and an outer membrane. It directly determines the accuracy of the measurement results of the CGM system, so the preparation process of the metal electrode is very critical. The metal electrode is printed with conductor lines (silver paste, carbon paste) on a PI/PET film with a thickness of 50um to 200um through screen printing, and the printing accuracy is required to be high. However, this process faces many challenges, and some companies are still struggling on the research and development road. For example, the base material curls after printing and drying, which often causes deviations in the secondary printing position, affecting the accuracy of the electrode; the base material itself has large errors, causing frequent alignment failures and other problems. In order to solve these challenges and accelerate the product development process, it is necessary to seek professional
