PRODUCT INFORMATION Ultrafine E-Glass Yarns High Performance Yarns for IC Substrate and Multilayer PCB Applications AGY’s Ultrane E-Glass yarns specically designed to meet the demanding performance requirements of IC substrate and multilayer PCBs. Product Application An ongoing trend in electronic devices is miniaturization – increasing device functionality in the same or smaller form factor. Continued growth in the use and functionality of smartphones and tablet PCs has created demand for thinner and higher performing PCB substrates. AGY Ultrane E-Glass yarns enable PCB designers to add more conducting layers in the same thickness of multilayer boards, and to develop the thinnest possible IC substrates. Product Description Ultrane E-Glass yarns are available in a wide range of ber micronage Features Low ber micronage and yield/tex • Enables more conducting layers in multilayer boards • Enables thinnest IC substrates Wide range of ber micronage and yield/tex Allows production of all current thin fabric PCB fabrics. Treated with electronics-grade starch/oil sizing Fabric surface smoothness with high-speed air-jet weaving Excellent conductive anodic lamentation (CAF) resistance Highly homogeneous glass quality Consistent performance in PCB applications Excellent balance of electrical and mechanical performance Allows designer to utilize both mechanical and electrical performance in PCB and yield/tex, allowing for production of all current thin fabric styles. The yarns are treated with AGY’s electronics-grade starch/oil sizing, facilitating high-speed air-jet weaving. Lower twist yarns are available to enable production of very
