Abstract

The invention discloses a micro-strip filter 3D printing manufacturing method. The method comprises the following steps: S1, designing a substrate printing pattern and a metal circuit printing patternaccording to a circuit pattern of a micro-strip filter; S2, extruding low-temperature co-fired ceramic slurry serving as a printing material out of a nozzle and depositing the slurry on a workbench to form a low-temperature co-fired ceramic substrate by using a 3D printer according to the substrate printing pattern; S3, curing the low-temperature co-fired ceramic substrate on the workbench in aninfrared heating mode; S4, spray-printing nano-silver metal ink serving as a printing material on the surface of the cured low-temperature co-fired ceramic substrate to form a metal circuit by using the 3D printer according to the metal circuit printing pattern; and S5, sintering the low-temperature co-fired ceramic substrate printed with the metal circuit by using a vacuum sintering furnace. Themethod is simple and easy to master, the production cost can be reduced, and a solution is provided for rapid manufacturing and individuation of the micro-strip filter.

Description

Technical field [0001] The invention relates to the field of additive manufacturing, in particular to a 3D printing manufacturing method of a microstrip filter. Background technique [0002] Parallel coupled microstrip filters are widely used in microwave circuits due to their simple structure. However, traditional microstrip filters are manufactured using printed circuit technology, which is complex and has a long period, and is not suitable for applications for rapid principle verification. [0003] In recent years, with the rapid development of 3D printing technology, the application of 3D printing technology in the field of electronic device manufacturing has become possible. Compared with traditional processes, 3D printing technology can simplify the process, reduce production costs, optimize the structure and performance, and can realize the personalized creation of microstrip filters. [0004] Therefore, the present invention provides a 3D printing manufacturing method of a ...
