Why Blind Via hole in HDI PCB
Microvias and stacked microvias can be desinged in High Density
Interconnect circuit boards, also known as HDI PCBs, to enable
complex interconnections in advanced designs.
Microvias, stacked microvias and via-in-pad design allow
miniaturization for higher functionality in less space and can
accommodate large pin-count chips such as the ones used in cell
phones and tablets. Microvias will help reduce layer count in
printed circuit board designs while enabling higher routing density
and eliminating the need for through vias.
Consumers' growing demand for more functionality in compact and
portable electronic devices—including PDAs, mobile phones, and AI
products—is pushing the industry toward smaller feature sizes,
finer process geometries, and more compact printed circuit boards.
For engineers addressing these evolving requirements, the adoption
of high-density interconnect (HDI) technology has become essential.
HDI PCB technology enables the production of circuit boards with
through-hole, blind, or buried vias without relying on conventional
mechanical drilling methods. To successfully implement HDI, users
must not only evaluate and apply this next-generation technology,
but also understand its limitations in areas such as layer stack-up
design, via and microvia formation, achievable feature sizes, and
the key distinctions between HDI and conventional printed circuit
board technologies.
