8-layer Through Hole PCB Circuit Board&pcba
Description:
Multi-layer circuit board assembly density is high, small size; As the size of electronic products becomes smaller and smaller, the demand for multi-layer circuit boards is also increasing.
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)
