#Didyouknow that fine pattern, thinner or thicker substrate design, impedance matching as well as many other various circuit design purposes rely greatly on your PCB’s Dielectric Constant(Dk)?
Especially for those of you working in networks or semiconductor IC packages, knowing a material’s Dk property and how it impacts PCB’s performance is a must.
Dk measures a material’s ability to concentrate electricity and, consequently, it affects the signal transmission’s speed. The lower the Dk, the faster the signal transmission.
That’s why Low Dk CCL, thanks to its high-speed quality, is a preferred substrate material for high-frequency, high speed applications.
But High Dk CCL is also a material considered for enabling substrates’ fine patterning and miniaturization, which is key for smaller but fine patterned applications including 5G mmWave AiP.
Doosan Electro-Materials provides a wide array of Dk solutions to match your PCB’s needs:
