Six-layer First-order Millimeter-wave Radar PCB Board&PCBA
Description:
Blind hole circuit board is the abbreviation of High Density Interconnector (High Density Interconnector), is a kind of (technology) for the production of printed circuit boards, and a circuit board with relatively high line distribution density using micro-blind hole technology. HDI is a compact product designed for small volume users.
Blind vias: A blind hole is a type of hole that connects the inner PCB line with the surface PCB line, and this hole does not penetrate the entire board. (Generally used in 4 layers and above)
Buried vias: The buried hole is only the type of hole connecting the line between the inner layers, which is not visible from the PCB surface. (Generally used in 6 layers and above)
Benefits: can increase the cable space;
Disadvantages: The process cost is very high, the general electronic products are not used, and only in particularly high-end products will be applied.
