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

Low hollow bers

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
