The Definition of FR-4 Printed Circuit Boards
FR-4 is a grade designation for flame-retardant fiberglass reinforced epoxy material. Thus, an FR-4 circuit board offers a much greater level of resistance to heat than a standard PCB. FR-4 circuit boards are divided into four classifications that are determined by the number of copper trace layers found in the material:
Four, six or 10 layers
More than 10 layers
Printed circuit board using FR4 as core material will be named as "FR4 PCB". PCB is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on.
FR-4 PCB Introduction:
High frequency board usually use FR4 glass fiber lamination, but also the whole of the epoxy glass cloth repression, more uniform color the entire pcb board, bright. Density larger than the low frequency pcb board
High-frequency electronic devices is the development trend, especially in the growing wireless networks, satellite communications, and information products to high speed and high-frequency, and voice communications products to large capacity and fast transmission of wireless, video, and data normalization.
the development of next-generation products require high frequency
board, satellite systems, mobile phone base stations and other
communications products received must be applied to high-frequency
circuit boards, and the inevitable rapid development in the coming
years, will be a large demand for high-frequency board.
