Are PCB Boards With Blind And Buried Vias Called HDI PCB?
HDI circuit boardsare high density interconnect PCB. The high density PCB that are plated with blind holes and then laminated are all HDI boards, which are divided into first-order, second-order, third-order, fourth-order, and fifth-order HDI. Simple buried vias are not necessarily HDI. .
The Difference Between hdi printed circuit boards And Ordinary PCB
Through Hole Circuit Board
Plating Through hole, or PTH for short, is the most common one. You only need to pick up the PCB and face the light, and the hole that can see the bright light is the "through hole". This is also the simplest type of hole, because when making it, you only need to use a drill or a laser to directly drill the through hole PCB. The cost is relatively cheap, but sometimes it will use more PCB space.
Blind Vias Hole
Blind via in PCB connects the outermost circuit of the PCB with the adjacent inner layer with electroplated holes. Because the opposite side cannot be seen, it is called "blind through". This manufacturing method requires special attention to the depth of the drilling (Z axis) to be just right; it is also possible to drill holes in the circuit layers that need to be connected in the individual circuit layers in advance, and then glue them together.
Buried Vias PCB
Buried hole, the connection of any circuit layer inside the PCB but not conducting to the outer layer. This process cannot be achieved by drilling after bonding. It must be drilled on the individual circuit layers. After the inner layer is partially bonded, it must be electroplated before it can be fully bonded. Compared with the original "through hole" and "Blind holes" take more time, so the price is the most expensive. This process is usually only used for high density interconnect PCB to increase the usable space of different types of PCB board layers.
