Affordable versatility in a CO2 laser solution for HDI via drilling. Leverage ESI’s laser expertise for PCB and substrate processing.

High-Density Interconnect

High-volume manufacturing of HDI PCBs requires blind (BHV) and through-hole (LTH) via processing; these vias are typically created with laser drills, which offer fast, reliable, and cost-effective processing at a miniaturized scale. ESI’s HDI systems enable HDI manufacturers to drill vias in a broad range of copper-clad base materials such as glass-woven reinforced epoxy resins (FR4) or other specialty materials. For PCB manufacturers of HDI boards, CO2 laser processing is the optimal choice for overall lower cost of ownership.

ESI leverages our expertise in laser processing and our proven track record of success in laser-based systems — especially in the flexible PCB manufacturing segment, where ESI is the clear market leader — and applies it to the HDI manufacturing segment. Our solutions are engineered to provide great reliability at high-quality output with the industry’s lowest cost of ownership, and backed by ESI’s professional service and support organization with local offices through the world.


Affordable versatility in CO2 laser via drilling for HDI applications.

nViant provides a CO2-based laser microvia drilling solution with a unique combination of high-quality via formation and high-accuracy, in a robust via drilling system that delivers high-volume laser processing throughput at a competitive price point. Maintain your PCB laser processing production throughput for HDI applications without sacrificing quality or accuracy.

The nViant via drilling system precisely drills blind (BHV) and through-hole vias (LTH) in coppercladded, glass woven reinforced materials (FR-4) at a typical range of 40 to 300µm, and enables pcb laser processing customers to Include rigid HDI processing as part of a broader portfolio of services and at a lower cost of ownership, while leveraging the experience of a laser systems provider that has a demonstrated history of applied laser expertise.
