  • Patent number: 8309210
    Abstract: 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.

  • Patent number: 8283032
    Abstract: The present invention relates to an electrical contact material having a surface layer made of a noble metal or an alloy having the noble metal as its main component, a method for manufacturing the same and an electrical contact using the same. Recently, electrical contact materials having excellent abrasion resistance are used for sliding electrical contacts such as a connector terminal of an automobile harness, a contact switch mounted in a cellular phone and terminals of a memory card. Although there have been known ones having an organic coating film composed of either aliphatic amine or mercaptan or a mixture of the both provided on the electrical contact material described above as the electrical contact materials having excellent abrasion resistance, they have had problems that even though they are effective with a low load of 0.5 N or below, abrasion accelerates when the load exceeds 0.5 N and sliding characteristics drop under a high-temperature environment.
