The stable operation of the walkie-talkie relies on the precise manufacturing of its core components.
The stable operation of the walkie-talkie relies on the precise manufacturing of its core components. The key components include the radio frequency module, baseband chip, speaker, microphone, battery, and casing, and the quality of each process directly determines the performance of the device. The radio frequency module, as the core for signal transmission and reception, undergoes three critical steps during production: surface mount welding, radio frequency calibration, and shielding treatment. Surface mount welding employs SMT surface mounting technology to precisely attach components to the PCB board, with an error control of less than 0.01mm to ensure stable signal transmission. The radio frequency calibration adjusts parameters such as frequency, power, and sensitivity through professional instruments to comply with national radio frequency band standards and avoid signal interference. The baseband chip is responsible for signal decoding and command processing. During production, it undergoes high and low temperature environment tests to ensure normal operation in extreme conditions ranging from -40°C to 60°C. The casing is mostly made of ABS engineering plastic or aluminum alloy, and undergoes processes such as injection molding, surface spraying, and wear resistance testing. It also takes into account protection performance and hand feel. The aluminum alloy casing requires additional anodizing treatment to enhance corrosion resistance. The battery, as the core for mobile power supply, undergoes production processes such as cell encapsulation, voltage detection, and cycle charging and discharging tests to ensure capacity meets standards and there is no leakage risk. It is also equipped with overcharge and overdischarge protection circuits to ensure safe use.
