Engineers Feel The Difference

Panasonic claims that the material offers the lowest transmission loss among the other materials used in the industry.

 

PCB material features

Panasonics new ultra-low transmission loss circuit board material has the following features:

 

The lowest transmission loss in the industry that allows semiconductor devices to operate steadily

Transmission loss: -18.7 dB/m. Panasonics conventional product*2: -20.6 dB/m (@20 GHz)

Excellent environmental durability that allows semiconductor devices to operate over a long period

Stable electrical characteristics under a high-temperature/high-humidity conditions

When the developed material and a conventional product are left in an environment at 130°C with a relative humidity of 85% for 800 hours:

Variation in dissipation factor: 0.0024. Panasonics conventional product: 0.0033

Less warpage which contributes to an improvement in circuit board manufacturing yield

Warpage: 310 µm. Panasonics conventional product: 410 µm
