Description

Technical Field

[0001] The utility model relates to the technical field of GPS antenna production, in particular to a GPS antenna double-sided printing machine. Background Art

[0002] GPS antennas, also known as Beidou antennas, require double-sided silver printing during production. The traditional method involves printing on one side of the ceramic substrate, drying it in a drying oven, and then printing the other side. This method requires a large number of factory operators and results in low production efficiency. To address this issue, existing patents, including Chinese patent application number 201810421404.6, disclose a double-sided printing system for Beidou antennas.
