Embodiment Construction
[0008] exist figure 1 Among them, the present invention is a method for manufacturing an ultra-long microwave high-frequency circuit board, which includes the following steps: Step 1, making a light-painting template: firstly, using GENESIS2000 to sequentially design the template and process the engineering documents according to the production process parameters, Make imposition of the processed files, and then use a high-precision laser photoplotter with a resolution of 10160dpi to photopaint the photopainted files into black negatives, develop, fix, clean and air-dry the photopainted negatives, and then use 100 ×100 microscope to inspect the negatives, and finally use the negatives as the master to copy the brown film with a 3KW exposure machine; Step 2, the production of material cutting and drilling: first use the electric shearing machine to cut out the required super-length according to the size requirements Microwave high-frequency copper-clad laminate, and then wrap t...
