EMBODIMENT
[0024] Please refer to Figure 1 - Figure 4 The embodiment includes R-FPC, R-FPC includes FPC end laser Senser 1, high thermal conductivity glass fiber double-sided adhesive 2, PCB connector end 3, FPC end thermistor 4, high thermal conductivity black nanometer PI film 5, PCB end two-dimensional code area 6.
[0025] High thermal conductivity black nanometer PI film 5 is arranged on the surface of R-FPC, and high thermal conductivity glass fiber double-sided adhesive 2 is covered on the surface of high thermal conductivity black nanometer PI film 5.
[0026] Wherein, a 12.5UM high thermal conductivity black nanometer PI film 5 is covered as a cover film layer on the surface circuit of R-FPC, and high thermal conductivity glass fiber double-sided adhesive 2 is added on the surface of high thermal conductivity black nanometer PI film 5, and the heat resistance temperature is set to 260 DEG C, when working, the heat generated by R-FPC can be radiated away quickly through high thermal conductivity black nanometer PI film 5, and the remaining heat is quickly delivered to the shell through high thermal conductivity glass fiber heat resistance 260 DEG C double-sided adhesive, so that the vehicle-mounted radar R-FPC can maintain stable performance in extremely harsh high-temperature environment to work at high sensitivity and prolong the service life of the equipment, can work continuously for 2 weeks in the environment of 85 DEG C and still maintain the performance of high sensitivity, and the service life of the equipment is also prolonged.
[0027] At this time, under the combined use of FPC end laser Senser 1 and PCB connector end 3, the information transmission is ensured to be fast and accurate, under the collection of FPC end thermistor 4 to temperature, the temperature receiving condition of the detection device is detected at any time, under the information tracing of PCB end two-dimensional code area 6, the accuracy and checkability of product identity are ensured.
[0028] FPC end laser sensor 1 is located at one end of the high-thermal-conductivity black nano PI film 5, and is used for emitting and receiving light;
[0029] The FPC end laser sensor 1 emits a beam of infrared or near-infrared laser pulses, which propagate at the speed of light, and when encountering a target object, part of the light is reflected back, and the FPC end laser sensor 1 captures the reflected light and records the time interval between the emission and reception of the laser pulse through the timer, and transmits the captured information to the mainboard through the PCB connector end 3. Since the principle and installation method of the mainboard are prior art, they are not described in detail in this embodiment.
[0030] The high-thermal-conductivity glass fiber double-sided adhesive 2 is used for heat transfer of the device;
[0031] After the heat generated by the R-FPC during operation is quickly radiated away through the high-thermal-conductivity black nano PI film 5, the remaining residual heat is quickly transferred to the shell through the high-thermal-conductivity glass fiber double-sided adhesive 2 to achieve sufficient heat dissipation.
[0032] The PCB connector end 3 is located at the other end of the high-thermal-conductivity black nano PI film 5 away from the FPC end laser sensor 1, and is used for connecting signal transmission;
[0033] Under the transmission of the PCB connector end 3, the information captured by the FPC end laser sensor 1 can be transmitted to the mainboard through the PCB connector end 3.
[0034] The FPC end thermistor 4 is located on the side of the high-thermal-conductivity black nano PI film 5 opposite the FPC end laser sensor 1, and is used for temperature acquisition;
[0035] When the body vehicle-mounted radar R-FPC is working, it will generate heat, and the FPC end thermistor 4 is responsible for collecting the temperature of the body vehicle-mounted radar R-FPC and transmitting it to the mainboard through the PCB connector end 3. When the external environment changes and the temperature of the body vehicle-mounted radar R-FPC continues to rise, approaching overload, the mainboard starts the cooling system to cool the body vehicle-mounted radar R-FPC, ensuring that the system operates under suitable temperature conditions, thereby maintaining stable operating performance and prolonging the service life of the equipment. The cooling system can cool in multiple ways, such as electric cooling, etc. Since it is continuously used in actual life, it belongs to prior art, and therefore is not described in detail in this example.
[0036] The high-thermal-conductivity black nano PI film 5 plays a role in heat radiation.
[0037] The heat generated by the R-FPC during operation is quickly radiated away through the highly thermally conductive black nano-PI film 5, while the residual heat is quickly and efficiently transferred to the shell through the highly thermally conductive glass fiber heat-resistant double-sided adhesive at 260 degrees Celsius, achieving sufficient heat dissipation.
[0038] The PCB end QR code area 6 is located on the side of the high thermal conductivity black nano-PI film 5 opposite to the PCB connector end 3. The PCB end QR code area 6 is used for information traceability.
[0039] The QR code area on the PCB serves six functions: information identification and full-process product quality traceability. It stores product identity information through text and QR code patterns, thereby achieving full-process product quality traceability.
[0040] During use, the heat generated by the R-FPC is rapidly dissipated through the highly thermally conductive black nano-PI film 5, while excess heat is quickly and efficiently transferred to the housing via high-thermal-conductivity glass fiber heat-resistant double-sided adhesive, achieving sufficient heat dissipation. This allows the vehicle radar R-FPC to maintain stable performance and high sensitivity in extremely harsh high-temperature environments, extending the equipment's lifespan. It can maintain high sensitivity performance even after continuous operation at 85 degrees Celsius for two weeks, further extending the equipment's lifespan.
