Problems solved by technology

[0002] Micro-RF chips have strict requirements on the force applied during testing, and the conventional technical solutions cannot accurately control the force. The main reason is that the actual force of the conventional chip during the contact process is determined by a variety of factors. The gravity of the chip, the applied force of the motor, and the internal friction will all affect the actual force of the chip, resulting in the fact that the actual force of the chip during the contact process cannot be accurately controlled
Moreover, the uniformity of the applied force is not easy to control, and the consistency of the measurement is not high.

Abstract

The invention discloses an apparatus able to accurately apply pressures on a miniature chip. The apparatus comprises a pedestal (2) and an elevating device (4) which is connected to the pedestal (2) and can elevate and descend. The apparatus is characterized in that the apparatus also comprises a casing pipe (6), of which the bottom portion is connected to the elevating device (4) via a spring (8), a weight block (10) which is a counterweight apparatus and connected to the sidewall of the casing pipe (6) and a workbench (14) arranged right below a pressure head (12). The lower end of the weight block (10) is fixedly connected to the pressure head (12). The miniature chip is installed on the upper surface of the workbench (14). According to the invention, on the premise that fully buffer is provided when the pressure head makes contact with the chip, forces applied to the miniature chip can be accurately controlled to guarantee stability and reliability in a test process and solve problems in the prior art.

Description

technical field [0001] The present invention is a device capable of precisely applying pressure on a microchip. Background technique [0002] Micro-RF chips have strict requirements on the force applied during testing, and the conventional technical solutions cannot accurately control the force. The main reason is that the actual force of the conventional chip during the contact process is determined by a variety of factors. The gravity of the chip, the applied force of the motor, and the internal friction will all affect the actual force of the chip, resulting in the inability to accurately control the actual force of the chip during the contact process. Moreover, the uniformity of the applied force is not easy to control, and the consistency of the measurement is not high. Contents of the invention [0003] The object of the present invention is to provide means that enable the actual stressing of the control chip. [0004] In order to solve the above problems, the pre...
