AGC’s EN-A1 alkali-free boro-aluminosilicate interposer glass has excellent engineering properties that provide electrical engineers with never-before-seen flexibility for designing next-generation entertainment, communications and display products.
EN-A1 is the premier interposer substrate for applications requiring high via counts. EN-A1 being a glass, will impart excellent chemical resistance, and a low CTE substrate that provides a stable foundation for your next design.
In addition, AGC‘s EN-A1 has proprietary refractive properties to allow for a low taper when laser drilled, providing for precise pitch control and hole size which facilitates higher via counts.
