On June 11, 2025, Huawei made a stunning debut with the Pura 80 series smartphones, quickly becoming the focus of the tech world. From design to performance, this series showcases Huawei’s innovative strength, with many highlights drawing attention. Behind this series of outstanding performances lies an ‘unsung hero’—the high-frequency probes, which play a crucial role in the manufacturing and testing of smartphones.
01What are High-Frequency Probes?
High-frequency probes, also known as ‘dual-head probes’, are high-end precision electronic components. They are small in size and require high testing accuracy, categorized into: dual-head—single-action probes and dual-head—dual-action probes.
High-frequency probes are primarily used in various communication power electronic components, semiconductor wafer testing, and chip packaging testing, featuring extremely low contact resistance and ultra-high bandwidth, capable of meeting the testing requirements for high-frequency signals ranging from 5 to 40 GHz.
Currently, the smallest probe diameter that Xian Deli can process is: needle tip φ: 0.06mm / needle tube φ: 0.10mm.
02Applications of Probes in Smartphones
Chip Testing
High-frequency probes play a key role in smartphone chip testing. The smartphone chip is the core component of a smartphone, and its performance and quality directly affect the overall performance of the phone. By contacting the smartphone chip with high-frequency probes, key parameters such as voltage, current, and frequency can be accurately detected, ensuring that the chip’s performance meets design requirements. This step is crucial for ensuring the stability and reliability of smartphone chips.
Screen and Camera Testing
High-frequency probes are also widely used in testing key components such as smartphone screens and cameras. The quality of the smartphone screen directly impacts the user’s visual experience, and high-frequency probes can accurately test parameters such as brightness, color, and resolution, ensuring that screen performance is optimal. For smartphone cameras, high-frequency probes can comprehensively test key indicators such as pixels, color reproduction, and clarity, providing users with a clearer photography experience.
Battery Testing
Additionally, in battery testing, high-frequency probes can accurately measure the battery’s voltage, current, and capacity, ensuring battery life and safety.
