LiDAR Cover
As more and more in-vehicle sensors such as LiDAR are being installed for automatic driving, anti-reflection films are required for the parts that cover them to improve their sensing function.
Uniform optical characteristics can be obtained by depositing an anti-reflection film with good adhesiveness on a three-dimensional cover. Furthermore, by using a special plasma processing technology, highly adhesive films that can withstand automotive environments can be deposited at high speed.
Special plasma treatment on a 45° inclined surface + 2-layer deposition: Good optical properties in the infrared region
High-speed Cu Electrode Deposition
There is an increasing need for micron-level Cu wiring on polycarbonate (PC) and other plastics for in-vehicle sensors and harnessless applications.
High-speed deposition makes it possible to deposit Cu electrodes at high speed, even on PC materials with low heat resistance.
| Cu film thickness | Tact | Work temperature |
|---|---|---|
| Up to 2.0 µm | Up to 5 min. | Up to 110 °C |
| Up to 1.0 µm | Up to 10 min. | Up to 120 °C |
Dry Seed Layer on Difficult-To-Plate Plastic
The special high-density plasma treatment and Cu sputter enable dry electroless plating layers possible. Patterning is easy and applicable to electrode formation on plastics such as MID*.
In addition to ABS, plating on difficult-to-plate materials (engineering plastics such as PBT, glass, etc.) is also possible.
