F4BM220 PCB weith Double-Sided 1oz or Hoz copper weight 6.0mm Thick ENIG
I’m here to introduce one of our high-performance PCB products: the double-sided PCB with F4BM220 base material. Designed for microwave, RF, and radar applications, this PCB delivers exceptional electrical performance, dimensional stability, and low dielectric loss. Its 6.1mm thickness, 10/10 mil trace/space, and immersion gold surface finish make it an excellent choice for high-frequency electronic systems.
1. Overview of the Double-Sided PCB
This double-sided PCB uses the advanced F4BM220 laminate, a material known for its low dissipation factor and precisely controlled dielectric constant. With a 6.0mm F4BM220 core and 1oz copper weight on both outer layers, this PCB is optimized for high-frequency designs that demand stable and reliable performance.
The immersion gold surface finish ensures excellent solderability and corrosion resistance, while the absence of solder masks and silkscreens allows for maximum focus on signal integrity. Manufactured to IPC-Class-2 standards, this PCB undergoes 100% electrical testing for quality assurance.
