Some package substrates are composed of glass fiber bundles and epoxy resin which have different electrical properties. These differences result in variations in characteristic impedance and propagation speeds, which may be detrimental at high data rates. The insertion loss (IL), within pair skew and differential to common mode conversion ratio of transmission lines may drastically increase due to the fiber weave effect. Consequently, the link budget of high speed communication channels may be significantly hindered. This paper addresses the problems due to the fiber weave effect and provides mitigation techniques at the package level, particularly for 56 Gbps Serializer/Deserializer (SerDes) interface.

Fiber Weave Impact on Crosstalk of High Speed Communication Channels in Glass Epoxy Packages
Durgun, Ahmet Cemal (2016-01-01)
Some packaging technologies utilize glass epoxy substrates that are composed of glass fiber bundles and epoxy resin. Because of the different electrical properties of glass and resin, the signal traces can have some variability, depending on their position with respect to the weaves. One of the parameters that are affected by the inhomogeneity of the substrate is the far end crosstalk. Crosstalk may significantly increase, hindering the link budget of high speed communication channels, especially in the den...
Effects of injection pressure and post-curing on the behavior of woven carbon fiber/epoxy composites produced by rtm (resin transfer molding)
Kaş, Yusuf Onur; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2002)
RTM (Resin Transfer Molding) is a closed mold process in which matrix resin is injected into a mold filled with a fiber preform. There are many RTM process parameters influencing the quality of the final product. The objective of this work was to study two of these variables: resin injection pressure and post-curing conditions. For this purpose, an amine curing epoxy resin was injected, by using a small laboratory size RTM machine, into a flat mold filled with woven carbon fiber layers. Various combinations...
Effects of RTM mold temperature and vacuum on the mechanical properties of epoxy/glass fiber composite plates
Kaynak, Cevdet; Isitman, Nihat Ali (2008-08-01)
The purpose of this study is to investigate the effects of mold temperature, application of vacuum at resin exit ports, and initial resin temperature on the mechanical properties of epoxy matrix woven glass fiber reinforced composite specimens produced by resin transfer molding (RTM). For this purpose, six mold temperatures (25, 40, 60, 80, 100, and 120 degrees C), two initial resin temperatures (15 and 28 degrees C), and vacuum (0.03 bar) and without vacuum (similar to 1 bar) conditions are utilized. Speci...
Effects of injection pressure in resin transfer moulding (RTM) of woven carbon fibre/epoxy composites
Kaynak, Cevdet (SAGE Publications, 2006-01-01)
RTM (Resin Transfer Moulding) is a closed mould process in which matrix resin is injected into a mould filled with a fibre preform. There are many RTM process parameters influencing the quality of the final product. The objective of this work was to study resin injection pressure. For this purpose, an amine curing epoxy resin was injected, using a small laboratory size RTM machine, into a flat mould filled with woven carbon fibre layers. Five different resin injection pressure levels; 1, 2, 3, 4, and 5 atm ...
DEVELOPMENT OF POLYMER MATRIX COMPOSITES WITH TUNABLE DIELECTRIC PROPERTIES
Özkaragöz, Nadire Nazlı; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2022-2-08)
Ferroelectric materials are used in different applications because of their superior electrical and dielectric properties. Ferroelectric materials are polarized when an electrical field is applied to the material. This spontaneous polarization continues even if an electrical field is removed. BST (Barium Strontium Titanate) is one of the attractive ferroelectric materials which has a high dielectric constant and low dielectric loss tangent (tanδ). High dielectric constant and low loss tangent are necessary ...
