#Didyouknow that low Df is key to high-frequency and high-speed PCBs? If you’re working in automotive, networks, or packaging, you might want to look into this.
When choosing the perfect CCL for your PCB, many factors need to be taken into consideration. Amongst them, the dissipation factor (Df) – which impacts signal transmission efficiency – should be carefully examined.
The lower the dissipation factor, the lower the signal loss. It is especially important in high frequencies because it affects signal loss to a greater extent than in low or middle frequencies.
Do you know why we use high-frequency materials in such areas as data centers, 5G mmWave, and automotive radars?
This is because we need to send high-frequency radiation, with the smallest possible signal attenuation. Meaning that signal loss – and consequently Df – is a decisive factor in your high-frequency PCBs’ quality.
Doosan Electro-Materials provides a wide array of Low Df CCLs to match your PCB’s needs:
