PCB-based LED lighting displays are common in the telecommunications and broadcasting industry. PCBs are applied in a variety of other functions within this industry as well. High-frequency amplifiers and filtering appliances commonly use PCBs, as do booster stations, receivers, frequency boards, mixing decks and microphones.

Multilayer PCBs are found in many telecommunication devices such as GPS and satellite applications, signal transmission, which demands durability while maintaining a high level of functionality. With the development of wireless technologies, there is a high demand for high-performance, Multilayer PCBs can easily fulfill the requirement. Other applications of telecommunication electronics are communication towers, Radar electronics, power amplifiers, attenuators, and many more.
