HDI (High Density Interconnector) PCBs utilize micro blind buried hole technology to create compact circuit boards for small-capacity applications. These boards feature microvias as interconnects between layers to accommodate high input/output density in advanced packages.
- Reduces PCB cost while increasing line density
- Enhanced electrical performance and signal integrity
- Improved reliability and thermal properties
- Better RFI/EMI/ESD protection
- Increased design efficiency
