manufacturers which has ten years productionexperience of high frequency microwave circuit board’s substrate.
high-frequencymicrowave circuit board (ptfe high-frequency microwave copper-clad board) is aspecial printed board suitable for high-frequency microwave circuits. due toits low dielectric constant, low dielectric loss, and low water absorption, itwill be widely used in mobile communications, military radar, aerospace,satellite communications, and high-frequency electronic circuits.
dueto many technical bottlenecks in its production processes and equipment, thereare no more than 10 manufacturers in the world which has mass production capability.in order to realize the localization of this important basic materials,guoneng has studied and researched for several years and benchmark the industry’sforeign giants: self-made high-speed gluing machines and high-temperaturelaminating machinesand develop laboratory equipment such as high-frequencyresonance method. it has become a high-frequency microwave circuit boardfactory with obvious technical advantages in china.
the current mass productswith dielectric constant as dk2.2 to dk4.0 has been widely used in mobilecommunication 3g/4g products and have expanded to be used in the militaryelectronics industry.
