Abstract:
A package substrate having sides, comprising:multiple non electrically conductive layers laminated together, each of the multiple non electrically conductive layers formed of; a first lamina formed of woven fibers having a first warp, the first warp of the first lamina disposed at a positive orientation of a first angle from the sides of the package substrate, where the first angle is neither zero degrees nor ninety degrees, a second lamina formed of woven fibers having a second warp, the second warp of the second lamina disposed at a negative orientation of the first angle from the sides of the package substrate, and the first lamina and the second lamina bonded together in a resin matrix to reduce warpage of the package substrate, and electrically conductive layers, with electrical connections dispersed between different ones of the electrically conductive layers.
