Excello Circuits provides a complete range of services to our customers in PCB prototypes and PCB manufacturing, allowing them the freedom to have a one stop shop for their PCB requirements. Our product offerings include rigid PCBs, rigid flex PCBs and HDIs.

HDI PCBs feature high-density attributes such as microvias, buried vias, and blind vias. These features enable more complex interconnections and improved performance in advanced technology applications.

HDI PCBs have higher interconnect density per unit area requiring more sophisticated technology and manufacturing processes for their production. HDI PCBs are boards with high-density characteristics including micro-sized holes, fine lines and can be constructed with thin high performance materials, thereby enabling more interconnected functions per unit area.

1+N+1 – PCBs contain 1 "build-up" of high-density interconnection layers.

i+N+i (i≥2) - PCBs contain 2 or more "build-up" of high density interconnection layers. Microvias on different layers can be staggered or stacked. Copper filled stacked microvia structures are commonly seen in demanding designs.
