Abstract:
The present invention provides a multilayer wiring board in which warpage during reflow soldering can be reduced even if there is no sufficient space for disposing a dummy pattern or if a dummy pattern cannot be disposed. A difference between the ratios of copper remaining in wiring layers causes a difference between the amounts of thermal expansion of the wiring layers. The fiber bundle content of at least one resin base material layer is made different from that of the other resin base material layers, to cause a difference between the amounts of thermal expansion of the resin base material layers. This difference between the amounts of thermal expansion of the resin base material layers is used to cancel the difference between the amounts of thermal expansion of the wiring layers. Thus, warpage of the board during reflow soldering is reduced.

Abstract:
Disclosed are systems or apparatuses and methods for forming a junction between conductive fibers that are incorporated into a fabric. Briefly, one method includes the steps of removing insulation from two intersecting individually insulated conductive fibers to expose the individually conductive fibers, bringing the exposed individually conductive fibers into contact with each other at a junction point, and forming a molecular bond between the conductive fibers at the junction point. Also disclosed are systems for forming a junction between conductive fibers that are incorporated into a fabric. In this regard, one embodiment of such a system can include a first apparatus that removes insulation from two intersecting individually insulated conductive fibers to expose the individually conductive fibers, a second apparatus that brings the exposed individually conductive fibers into contact with each other at a junction point, and a third apparatus that aids in formation of a molecular bond between the conductive fibers at the junction point.
