HDI(High Density Interconnection)
High-density interconnection (HDI) substrates have high-density circuits that make it possible for electronic parts mounted on a PCB to send and recieve electrical signals between themselves. The products are used for mounting the main parts of mobile devices and transmitting their signals.

SAVIA (SAMSUNG All layer VIA) allows for transmission of signals at high speeds by making PCBs smaller and shortening signal paths.
All Layer Via is formed across all layers through fill plating. Staggered Via is formed through transmission and reflection.
Stiffness is enhanced by using thin materials with high coefficient of elasticity. Electric signal characteristics are excellent as materials of low permitivity are used.
Stiffness is increased by applying materials with high coefficient of elasticity, and thereby improving the quality of partsmounting through the enhanced flex characteristics of slim PCBs (60 ㎛ CCL, 40/50 ㎛ Prepreg).
Electric signal characteristics are excellent as microcircuits and materials of low Dk (low permitivity) are applied.
Cavity PCBs have step differences in the areas where components are mounted. They allow a reduction in the overall thickness even if a thick component is mounted.
There are two cavity types: noncomponent and component. Whereas the former type cannot be mounted with components, the latter has SRs and pads formed in a way that allows the mounting of components.
