New invention patent approved
Thunder Precision Resistor Co., Ltd. had disclosed an invention of an ultra-high frequency RF resistor and a production method thereof. The new invention patent had be approved and issued.
The diamond substrate is used as the substrate material, the composite heat dissipation substrate is used to improve the heat dissipation efficiency, and the special packaging material is used to further improve the heat dissipation performance of the RF resistor.
The production method uses liquid nitrogen cooling to control the temperature rise of laser resistance adjustment, laser seamless welding and laser cutting, so as to prevent the resistance value variation of the resistance layer of the RF resistor during the production process.
