The factors influencing screen printing precision
PCB printing patterns that include the following two aspects: one refers to the graphic printing lines to picture distortion is small, line width precision of 0. 05mm； 2 refers to the printed graphics location accuracy requirement is high, the graphic length is 500 mm, inside location problem & lt; 0. 15 mm, affects the accuracy of the above-mentioned two aspects has a variety of factors, from screen plate making to graphic printing production process, important factor has the following several aspects:
1. Silk screen plate making the choice of the material and printing materials: bag net frame material, silk screen material, mesh, color, and printed material performance;
2. Screen printing set equipment deployment, tooling: screen printing machine, positioning jig, etc.
3. Production process includes stretch mesh, screen plate making, printing process, etc. ;
4. Things of garden environmental conditions: temperature, humidity, cleanliness, especially cleanliness are the important factors that affect product case quantity;
5. People is the most important factors affecting the quality of engineering, the operator must have a high sense of responsibility and high skills essential.
before the focus on several aspects of the factors on the printed graphic printing effect of the principle and progress of the pace of the precision and the main point.
