[Under development] Low-κ thermosetting tape for FPCs
Bonding sheet for high-speed transmission FPCs that can be used for both liquid crystal polymer (LCP) and modified polyimide (M-PI)
-
- Product name
- D5300P series
-
- Features
-
- Low transmission loss due to low dielectric constant
- The product can be used for both LCP and M-PI that are used for base material for high-speed transmission FPCs.
- Existing FPC manufacturing equipment can be used because the tape thermally cures at 180℃.
- This Novel formulation optimizes low dielectric constant with a high bonding strength. This technology enables the manufacture of highly reliable FPCs.
