Abstract
A thermoplastic composition for use in a fine pitch electrical connector is provided. The thermoplastic composition contains a liquid crystalline polymer and a plurality of fibers. The volume average length of the fibers in the thermoplastic composition is selectively controlled according to the present invention so that it is within a certain range, such as from about 80 to about 250 micrometers. The fibers also have a narrow length distribution. That is, at least about 70% by volume of the fibers have a length within a certain range. Through the use of a liquid crystalline polymer and fibers of a certain weight average length and narrow length distribution, the present inventors have discovered that the resulting thermoplastic composition is able to achieve a desirable combination of strength and flowability, which enables it to be uniquely suited for the walls of a fine pitch connector.
