Abstract

The invention discloses a multi-print head printing and integrated manufacturing method of an LTCC (low temperature co-fired ceramic) filter. The integrated jet printing of an LTCC filter is implemented through the following process flows: LTCC filter model building, multi-layer LTCC filter jet printing and firing. According to the manufacturing method provided by the invention, a multi-layer embedded integrated and miniature LTCC filter with required dielectric constant, low loss and high Q can be manufactured; flexible manufacturing of devices can be realized to satisfy special needs in different areas; and meanwhile, the method has the advantages of simple process, less required equipment, low cost and high manufacturing speed, thereby providing a new method for LTCC filter manufacturing.

Description

technical field [0001] The invention belongs to the technical field of electronic device manufacturing, and relates to an LTCC filter multi-nozzle printing integrated manufacturing method. Background technique [0002] Three-dimensional printing (Three Dimensional Printing, 3DP) or additive manufacturing (Additive Manufacturing) is an advanced forming technology that prints the cross-section of an arbitrary-shaped digital model layer by layer and accumulates it. It can quickly manufacture personalized and complex structural feature parts. The printing of the nozzle can realize the direct manufacture of multi-material, functionally graded material, cross-scale and complete functional structure, and has a wide range of applications in the fields of medical care, aerospace and mechatronics. [0003] A filter is a two-port network that is frequency selective. Microwave filters are widely used in systems such as microwave communication, radar navigation, electronic countermeasur...
