Embodiment 1

[0033] Below, refer to figure 1 and figure 2 The pressure applying device 100 according to the present invention will be described.

[0034] First, use figure 1 The configuration of the pressure applying device 100 according to the present invention will be described.

[0035] like figure 1 As shown, the pressure application device 100 includes a pressure rod 110 and a pressure hammer 120 . The pressing rod 110 may penetrate the pressing hammer 120 vertically.

[0036] Optionally, the pressure applying device 100 may further include an outer spring 130 surrounding the pressing rod 110 and arranged to abut between the top of the pressing rod 110 and the top surface of the pressing hammer 120 . Thus, for example, the outer spring 130 can play a function of buffering the movement of the pressing rod 110 relative to the pressing hammer 120, so as to further buffer the pressure exerted by the pressing rod 110, so that the pressure can be gradually changed during the adjust...

Embodiment 2

[0047] Below, refer to Figure 3 to Figure 6 The test equipment 300 for device electrical performance (eg, radio frequency signal) measurement according to the present invention will be described.

[0048] First, use image 3 The structure of the test equipment 300 according to the present invention will be described.

[0049] like image 3 As shown, the test apparatus 300 for device electrical performance measurement may include a base 310 , a test board 320 , and a pressure applying device 330 . The base 310 can be located below the pressure applying device 330, and the test board 320 can be placed between the base 310 and the pressure applying device 330, and can be used to carry the device to be tested (not shown). Optionally, the testing device 300 may further include a limiting portion 340 .

[0050] The pressure applying device 330 includes a pressure rod 331 and a pressure hammer 332 . The structures and functions of the pressure applying device 330 , the pressing...

Embodiment 3

[0059] Below, refer to Figure 7 The method 700 for measuring electrical properties (eg, radio frequency signals) of a device involved in the present invention will be described.

[0060] The test equipment used in this embodiment for measuring the electrical properties of the device is the same or similar in structure and function to the test equipment 300 described in Embodiment 2, and thus will not be repeated here.

[0061] The method 700 begins at step S701. At step S701, the test board is placed on the base of the testing device, and the plurality of test board holes of the test board are respectively aligned with the plurality of positioning holes of the base and thereby the test board is fixed to the base.

[0062] Next, at step S702, the device is placed on the test position of the test board so that the device is aligned with the circuit interface on the test board.

[0063]Next, at step S703, the pressure applying device is made to enter the space defined by the p...

Abstract

The invention provides a pressure applying device and test equipment which comprises the pressure applying device and is used for measuring a radio frequency signal of a device. The pressure applying device comprises a pressing hammer; the pressing rod vertically penetrates through the pressing hammer, the pressing rod comprises a main body part, and a cavity is formed in the lower part of the main body part; the pressing head is coupled to the lower part of the cavity in a sliding manner; the inner spring is arranged in the cavity, one end of the inner spring abuts against the top surface of the cavity, and the other end of the inner spring abuts against the pressing head.

Description

technical field [0001] The present application relates to a pressure application device, a test apparatus incorporating the pressure application device, and a method of measuring a radio frequency signal of a device using the test apparatus. Background technique [0002] Surface acoustic wave (SAW: surface acoustic wave), bulk acoustic wave (BAW: bulk acoustic wave) (for example, thin-film bulk acoustic wave (FBAR), etc.) are currently three mainstream technologies in the field of filters for mobile devices. Among them, the low-frequency and mid-frequency bands are dominated by SAW filters. Surface acoustic wave (SAW) devices are electronic devices based on the piezoelectric effect of piezoelectric materials and use the surface acoustic waves on the surface of piezoelectric materials. The interdigital transducer (IDT: interdigital transducer) on the surface of the electrical material (a metal electrode with a quasi-periodic structure, whose shape is like the cross of two han...
