Tired of sacrificing throughput to get the quality you need in IC packaging? Get the right combination of accuracy, precision and speed with the CornerStone laser microvia drilling platform.

Meet design requirements for smaller vias and higher accuracy.

The demand for ever-smaller microvias and higher feature density in increasingly delicate flexible and rigid-flex circuits is driving increased worldwide adoption of ESI systems. Our IC packaging systems excel in accuracy, power control, reliability, and productivity to achieve lower overall cost of ownership.


Accuracy and throughput in a laser microvia drilling system.

CornerStone helps circuit packaging manufacturers meet the microvia drilling demands of processing next-generation products. With its unique combination of high-accuracy microvia formation, high-volume throughput capabilities and an industry-leading footprint size, CornerStone allows integrated circuit manufacturers to easily address a wide range of IC packaging design requirements and drill smaller vias at a low total cost of ownership.

Incorporating ESI’s patented Third Dynamics beam positioning technology in a multi-beam format, CornerStone provides per-beam via drilling rates that significantly outperform other high-volume manufacturing laser via drilling systems. The resulting productivity leads the PCB laser processing industry and significantly lowers PCB manufacturing customers' cost of ownership.

As next-generation substrates push the requirements for line space and signal routing, target pad and via diameters necessarily decrease, requiring a commensurate improvement in via drilling placement accuracy. CornerStone offers industry-leading via drilling placement accuracy, and can be extended for even smaller and denser via drilling requirements in the future.

CornerStone has an overall footprint that is 25 percent smaller than typical laser via drills, helping to deliver significant productivity increases and substantial savings for PCB laser processing customers, as they extend their via drilling production lines for additional PCB laser processing capacity.
