As electronic devices continue to develop towards thinness and high-speed, Micro Coaxial Cable has been widely used in applications such as laptops, tablets, camera modules, medical equipment, and other scenarios with extremely high requirements for signal integrity and anti-interference performance. However, the processing difficulty of ultra-thin coaxial cable bundles is extremely high, and a slight mistake may cause signal loss or structural damage.
The three major technical challenges of ultra-fine coaxial beam processing
Extremely thin wire diameter, extremely small operating space
Taking the commonly used AWG#40 specification as an example, the conductor diameter is only 0.09mm, and the overall outer diameter is only 0.37mm. Traditional welding methods are prone to core breakage or insulation damage, with extremely small process tolerance, making it difficult to guarantee the yield of finished products.
Welding precision is extremely high
The internal structure of the extremely thin coaxial cable consists of an inner conductor, insulating layer, shielding layer, and sheath layer. During welding, it is necessary to ensure that each layer is intact and undamaged. The weld joint must be clean and firm, while avoiding affecting the signal transmission performance.
It is difficult to control the consistency of high-frequency signals
Due to the fact that ultra-fine coaxial cables mainly undertake high-speed data transmission tasks, any minor defects in processing can cause signal attenuation, reflection, or crosstalk, thereby affecting the overall system performance.
HTK LVC-D30LPMSG+ : Micro coaxial cable connector for specialized applications
In response to the above challenges, HTK (Honda Tsushin Kogyo) has launched the LVC-D30LPMSG+ connector, which is specifically designed for ultra-thin coaxial cable bundles. This series has been optimized in terms of structure, performance, and process compatibility, making it an ideal choice for high-density signal transmission systems such as laptops and LCD monitors.
