Thunder Precision Resistor Co., Ltd. disclosed the process and preparation methods of making a new kind of UHF RF resistors: (1) Take a certain mass of nano silicon carbide with a particle size of 20nm ~ 50nm and disperse it in 95% ethanol with a mass multiple of 5 ~ 8 times, and then add nano alumina with a particle size of 20nm ~ 50nm with a mass of 2 ~ 3 times of nano silicon carbide to fully disperse it; (2) Add silane coupling agent dl602 with 2% ~ 3% mass of nano silicon carbide, fully stir until the system thickens, and then add organic Polyborosilazane iota-9120 with 0.3 ~ 0.5 times mass of nano silicon carbide to fully disperse; (3) in air atmosphere, the mixture of step 2 (step 2) was desiccant and cured by spray drying method, and the modified filler was prepared.

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.

RN series high stable metal film resistors with stability established Thunder Precision Resistor Co., Ltd. makes RN series resistors that meet requirements of MIL-R-55182 with established reliability. The hard Bakelite mold construction provides superior moisture protection RN series high stability resistors are made of 96% alumina ceramic cores sputtering with high grade professional metal film trimmed with the professional laser machines to achieve uniform helix grooves without hurt the ceramic cores. The production procedure is introduced from Europe in 1989. All materials of to make RN series high stability resistors have been keep the same as they are introduced to guaranty the high quality and high stability as well.
