HASL Lead Free Multilayer Communication PCB Assembly Heavy Copper Impedance Control PCB 6mm
Communication PCB Assembly Description
With the rapid development of information and communication technology, electronic devices such as smart phones, wireless routers, base stations and other communication equipment have become an indispensable part of People's Daily life and work. The printed circuit boards in these devices are the basis for the assembly of components and integrated circuits, capable of transmitting high-speed signals and data that make communication possible.
Communication device PCBS use conductive copper traces etched from a copper-covered laminate to facilitate the interconnection between active and passive components. They provide the mechanical support and necessary electrical connections determined by the intended function of the device. But most importantly, PCBS designed for communication applications must transmit signals accurately and reliably between components without unacceptable loss or interference. This requires specialized materials and manufacturing processes to meet the unique needs of high-frequency communication electronics.
Communication PCB Assembly Application
In the field of communication, communication PCB board is widely
used in wireless network, transmission network, data communication.
And fixed line broadband. Related PCB products include backboards,
high-speed multilayer boards, high-frequency microwave boards, and
multifunctional metal substrates.
PCB requirements in the field of communication are divided into
subdivisions such as communication equipment and mobile terminals.
Communication equipment is a communication infrastructure mainly
used for wired or wireless network transmission. Including
communication base stations, routers, switches, etc. Communication
equipment mainly uses high-rise PCB boards, of which 8-16 layers
account for about 42%. The mobile terminal is mainly HDI and
flexible board.
