Patent number: 8320133Abstract: According to one embodiment, a circuit board comprises an anisotropic film disposed outwardly from a first flexible dielectric layer, and a second flexible dielectric layer disposed outwardly from the anisotropic film. The first and second flexible dielectric layers each have at least one conductive trace conductively coupled to a pad. The anisotropic film forms a via region that conductively couples the pad of the first flexible dielectric layer to the pad of the second flexible dielectric layer, and electrically isolates the conductive trace of the first flexible dielectric layer from the conductive trace of the second flexible dielectric layer.Type: GrantFiled: December 5, 2007Date of Patent: November 27, 2012Assignee: Raytheon CompanyInventors: Harold S. Fenger, Ike Y. Chang, Richard W. Nichols

Patent number: 8309210Abstract: A laminate for a printed wiring board (PWB) in which the laminate has a resin system containing a binder. The binder is made of ultra-fine binding particles that reinforce the resin system thereby reducing adhesive and cohesive failure of the laminate. The particles in addition to reducing occurrences such as pad cratering, eyebrowing, and tail-cracking, have the benefits of increasing thermal heat transfer and reducing resin shrinkage. The particles are preferably the same material as a reinforcing material contained in the laminate which can be a woven glass.Type: GrantFiled: September 13, 2010Date of Patent: November 13, 2012Assignee: Rockell Collins, Inc.Inventor: Roy M. Keen
