Precision Mobile Phone Data Test Fixture for Streamlined Consumer Electronics Manufacturing
Header include
The mobile phone data test fixture is a high-precision functional verification platform specially designed for the manufacturing process of consumer electronic products. As a dedicated interface device connecting the mobile phone under test with the automated testing system, it precisely matches the radio frequency, high-speed signals and electrical performance to achieve rapid and automated detection of the communication modules and port functions of mobile phones in the production process. It is a key process equipment for ensuring the quality and consistency of terminal products.
Abject of manufacture
1.The main structure: It adopts a combined framework of 6061 aluminum alloy profiles and bakelite/fiberglass resin boards, which takes into account both rigidity and strength as well as insulation properties
2.Core components: including high-frequency probe modules, RF coaxial connectors, precision positioning pins, pneumatic bonding mechanisms and signal transfer boards
3.Adaptation object: Customized design for the test interface (such as USB-C/Pogo Pin array) and profile of specific mobile phone models
Core features and requirements
1.Micron-level positioning accuracy: The repeatability accuracy of the positioning mechanism should be ≤0.01mm to ensure the consistency of the interface position of the tested mobile phone each time it is placed.
2.High-frequency signal integrity: The impedance of the RF transmission path is strictly controlled at 50Ω±2%, and the insertion loss is ≤0.5dB@6GHz
3.Modular compatibility design: It adopts quick-change probe modules and programmable adapter boards, supporting rapid line changing production for multiple models of mobile phones in the same series
4.Durability indicators: The core probe life is ≥ 500,000 times, and the fatigue resistance cycle of the pressing mechanism is ≥ 1,000,000 times, meeting the strength requirements for mass production
5.Ergonomic optimization: Equipped with anti-misalignment mechanisms, visual positioning assistance and one-handed operation design, it enhances the operational efficiency of the production line
Key processes and technologies
1.Precision machining technology
(1)A CNC machining center guided by a three-coordinate measuring instrument is used to ensure that the position accuracy of the installation hole is ±0.005mm
(2)Hard anodizing treatment (with a thickness of 25-30μm) is adopted to enhance the wear resistance and grounding performance of the positioning surface
2.High-frequency circuit process
(1)The four-layer gold plating process was applied to test the base plate, and impedance matching and shielding treatment were carried out on the key signal lines
(2)The thread anti-loosening structure of the RF coaxial connector is adopted to ensure the connection stability during continuous testing
3.Integration of intelligent detection systems
(1)Integrated photoelectric sensors enable in-situ detection of the object under test
(2)Configure a pressure monitoring module to provide real-time feedback on the probe contact force (range: 50-150g±10g)
(3)The product model is automatically identified through the barcode scanner and the corresponding test program is called
4.Calibration and verification system
(1)Establish a standard gold sample comparison mechanism
(2)Establish a standard gold sample comparison mechanism
(3)Equipped with dedicated calibration fixtures for in-situ accuracy compensation
Conclusion
The mobile phone data test fixture, by integrating precision mechanical processing, high-frequency circuit design and intelligent detection technology, has established a quality checkpoint in the manufacturing process of consumer electronics. Its micron-level positioning accuracy and complete signal transmission capability ensure the reliability of test data, while the modular design and durability considerations directly support the core demands of modern intelligent manufacturing for high-efficiency and high-flexibility production, becoming an important engineering and technical carrier connecting product design and mass production quality.
