At present, the positioning of Rc Car Circuit Board SMT has gradually evolved from general production technologies such as connection and assembly to a key technology for achieving highly diverse electronic information equipment. Higher density, smaller bumps, lead-free processes, etc. require new packaging technologies that are more adaptable to the rapidly changing needs of the consumer electronics market. The innovation of packaging technology has also become a powerful driving force for the continued development of semiconductor and electronic manufacturing technology, and has a significant impact on the improvement of semiconductor front-end technology and surface mount technology.
(1) The output of the two voltages may be the difference in size. When the battery power may be more obvious, it is recommended to use a small voltage as the steering motor alone;
(2) The remote control distance is long. When the power is sufficient, there is no interference. After about 10 meters, the antenna is correctly connected. The above is for reference only.
(3) In order to improve the sensitivity of the remote control, please equip the motor with a fire-fighting capacitor.
