What is a semiconductor high-frequency needle?    

Semiconductor high-frequency probe, also known as "dual head probe", is a high-end precision electronic component. It has a small volume and requires high testing accuracy. According to its structure, it can be divided into two series: double head single action probe and double head double action probe.

Semiconductor high-frequency needles are mainly used for various communication power electronic components, semiconductor wafer testing, chip packaging testing, and other processes with extremely low contact resistance and ultra-high bandwidth, which can meet the testing requirements of 5-40G high-frequency signals.

At present, Centalic can process the minimum probe diameter: needle diameter: 0.06mm/needle tube diameter: 0.10mm.

Chip testing

Semiconductor high-frequency needles play a crucial role in mobile phone chip testing. Mobile phone chips are the core components of smartphones, and their performance and quality directly affect the overall performance of the phone. By contacting the semiconductor high-frequency needle with the mobile phone chip, key parameters such as voltage, current, and frequency of the chip can be accurately detected, ensuring that the performance of the chip meets the design requirements. This step is crucial for ensuring the stability and reliability of mobile phone chips.

Screen and camera testing

Semiconductor high-frequency needles are also widely used for testing key components such as mobile phone screens and cameras. The quality of mobile phone screens directly affects the user's visual experience, and semiconductor high-frequency needles can accurately test parameters such as brightness, color, resolution, etc. of the screen to ensure optimal screen performance. For mobile phone cameras, semiconductor high-frequency needles can comprehensively detect key indicators such as pixels, color reproduction, and clarity, providing users with a clearer photography experience.

battery test

In addition, in battery testing, semiconductor high-frequency needles can accurately measure the voltage, current, and capacity of the battery, ensuring battery endurance and safety of use.
