The PET film button board is widely used in the fields of mobile phone remote control, multimedia and other electronic products. It acts as a flexible switch.

The development of flexible PCB connectors also changes with the changes in electronic equipment. With the trend of small pitch, multiple pins, small size, high integration, and multiple contacts, flexible PCB connectors must be designed from appearance to product performance and quality.

Most PCBs used in automobiles are 4-layer, 6-layer, 8-16-layer boards. The production requirements for automotive electronic PCB boards are not much different from ordinary PCBs in design. The defect rate is mainly reflected in the process. The PCB is low, and the requirements for vibration and high temperature performance are higher.

Compared with 4G, the number of 5G base stations will increase. Due to the high-speed and high-frequency characteristics of 5G, as far as a single base station is concerned, the value of the communication board will also be greatly improved.

The antenna is an important part of the Bluetooth earphone PCB. The PCB has through and metalized vias, and the walls of the vias form a conductive layer; the antenna conductor is etched on the upper antenna conductor of the copper foil on the top of the PCB and under the copper foil on the bottom of the PCB The antenna conductor, the antenna's radiation intensity and radiation efficiency are in the optimal state, which can effectively realize the reliability and stability of the Bluetooth headset product.

Smart phones are small in size and generally use rigid PCB and flexible PCB. PCB reduces wiring and assembly errors, saves equipment maintenance, debugging and inspection time, facilitates mechanized and automated production, improves labor productivity and reduces the cost of electronic equipment. The design can be standardized to facilitate interchangeability.
