What are the common application fields of screen printing in the electronic industry, and what functional requirements can it meet?

Screen printing is widely used in the electronic industry, including the production of printed circuit boards (PCBs), touch panel electrodes, battery electrodes, display screen optical layers and electronic component marks. In these applications, it can meet various functional requirements: it can print conductive patterns to realize current transmission for PCBs and electrodes; it can deposit insulating layers to prevent short circuits between electronic components; it can print light-shielding and anti-reflection layers for display screens to improve visual effects; and it can also print identification marks such as product models and parameters for traceability and identification.
