Panasonic has developed an ultra-low transmission loss circuit board material (Product No. Laminate R-G545L/R-G545E, Prepreg R-G540L/R-G540E) that is suitable for use in semiconductor packages and modules. The newly developed material allows the stable operation of semiconductor devices that process enormous data at a high speed.
Due to the expansion of IoT (Internet of Things) network and the launch of the fifth-generation (5G) mobile communications system scheduled to be implemented in 2020. It is expected that the data communication will become further larger in volume and faster. This circumstance has created a demand for circuit board materials used in semiconductor packages and modules that need to be adapted for high-speed/large-capacity data communication applications. From its original resin design technology, the company has developed the circuit board material with ultra-low transmission loss for semiconductor packages and modules.
Key Features:
- Ultra-low transmission loss that allows semiconductor devices to operate steadily
- Transmission loss: -18.7 dB/m. Panasonic's conventional product: -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. Panasonic's conventional product: 0.0033
- Less warpage which contributes to an improvement in circuit board manufacturing yield
- Warpage: 310 µm. Panasonic's conventional product: 410 µm
