Problems solved by technology

As for the dielectric constant (DK) and dielectric loss (DF) of glue at different frequencies, glue manufacturers usually only provide DK and DF at extremely low frequencies such as 10KHz. For the millimeter wave frequency band, on the one hand, the test equipment is expensive. On the other hand, the glue will stick to the measuring instrument and cannot be directly measured. These factors make it difficult for manufacturers to provide DK and DF when the glue works in the millimeter wave frequency band.

The test method can test the performance parameters of the glue at low cost, especially the performance parameters of the glue in the millimeter wave frequency band.

Description

technical field [0001] The invention relates to a test method for glue performance parameters. Background technique [0002] For the 5G millimeter-wave antenna module, the industry chooses to combine the RF chip and the substrate antenna to form an AIP (antenna-in-package) to reduce the RF system loss, and this has higher integration and better performance. The AIP composed of the dielectric resonator antenna module is an excellent solution because the number of PCB layers required is greatly reduced compared with the number of substrate layers of the previous AIP, and the processing accuracy is high and the cost is low. [0003] However, the dielectric resonator antenna still needs to be integrated with 2-3 layers of PCB boards for matching and interconnection. Usually, the PCB boards are connected and fixed by glue. As for the dielectric constant (DK) and dielectric loss (DF) of glue at different frequencies, glue manufacturers usually only provide DK and DF at extremely ...
