The primary challenges manufacturers face are related to processing materials and components at an ever-smaller scale and ever-higher levels of precision.
As the world’s leading innovator in flex laser via drilling solutions, ESI applies decades of laser, optics, and motion control expertise to the application challenges customers face, ranging from simple coverlay cutting to the advanced high-speed blind via drilling and circuit patterning processes. Our family of flex solutions are engineered to deliver the combination of speed, accuracy, and performance our customers need to elevate production and push the boundaries of possibility.
SPOT ON™ increases performance by delivering a dynamic beam focus capability to high-production Flex PCB manufacturing. This capability enables beam location and control through automated z-mapping and dynamic z-control. With the SPOT ON™ feature, the CapStone™ system maps inconsistencies in height between the chuck, overlay, and panel. Once mapped, the system automatically adjusts the beam spot to deliver quality vias without waste.
