Description

Technical Field

[0001] The invention belongs to the field of circuit board production, and in particular relates to an adjustable circuit board printing chassis. Background Art

[0002] Printing technology is the entire process of printing and reproducing visual and tactile information. It is a technology that reproduces art, text, and images in batches according to demand through planning, photography, word processing, art design, editing, color separation, plate making, printing, and post-printing molding. Printed circuit boards have developed from single-layer to double-layer boards, multi-layer boards, and flexible boards, and are constantly developing in the direction of high precision, high density, and high reliability, constantly reducing the size, reducing costs, and improving performance. The development trend of printed circuit board production and manufacturing technology is to develop in the direction of high density, high precision, fine aperture, fine wire, small spacing, high reliability, multi-layer, high-speed transmission, light weight, and thinness in terms of performance.
