Samudy Precision Injection Molding (Shenzhen) Co., Ltd.   Jiang Liangyong

Overview

To remain competitive in modern consumer electronics products, antenna components must achieve miniaturized and lightweight designs while ensuring signal performance and cost-effectiveness. A leading consumer electronics manufacturer approached TK Precision with a requirement: to adopt PDS antenna manufacturing technology and provide a solution that iteratively upgrades its existing coil antenna solution while adjusting the space to provide a larger storage location for the battery and enhance product endurance. Combined with the housing structure, the new PDS antenna adopts an integrated one-piece molding production design. Through rigorous performance testing, it leads the original coil antenna across indicators such as S11/Gain/Efficiency, and in actual verification tests doubled the communication distance, earning customer recognition.

Solution

TK Precision's solution is its innovative Printed Direct Structuring (PDS) antenna, which uses high-precision pad printing technology to replace the original coil antenna structure. Without changing the exterior housing, through scientific design it makes full use of the internal space of the housing to expand signal coverage, thereby increasing communication distance, while reducing production time, lowering processing costs, and reducing product weight. It also facilitates battery expansion, thereby improving endurance at the same time. Customer actual tests show that at the same power level, the device's unobstructed signal coverage distance increased from 20 meters to 39 meters, a communication efficiency improvement of up to 95%.

Results

The solution improved operational flexibility and delivered significant performance gains and cost savings to the customer.

• Breakthrough Innovation:PDS printing technology provides better high-frequency electromagnetic characteristics than the original coil;
• Structural Lightweighting:Flexible integrated substrates replace metal coil assemblies, reducing antenna weight;
• Cost Optimization:Automated pad printing technology minimizes material consumption and eliminates soldering steps, thereby simplifying the production process;
• Endurance Optimization:The PDS antenna does not occupy the original antenna space, expanding battery capacity for longer standby.
