Multiaxially oriented thermotropic polymer substrate for printed wire board |
| 摘要 |
The present invention is directed to the use of multiaxially oriented (e.g., biaxially) thermotropic polymers as a substrate material for the preparation of printed wire boards (PWB). In preferred embodiments, the PWB of the present invention comprises a generic, high density, organic multilayer PWB comprising XYDAR TM and/or VECTRA TM films, capable of being employed as a high density leadless perimeter and in grid array ceramic chip packages.
