Disclosed are structures comprising a composite of fluorinated particulate carbon dispersed in a polymer, the fluorinated carbon being present in an amount sufficient to reduce the dielectric constant of the composition, the structure also including electrical conductor patterns. The composite can be made conductive by irradiating it with an UV excimer laser.

Fluorinated carbon polymer composites

Disclosed is a process of effecting a change in the dielectric constant and coefficient of thermal expansion of a polyimide material, by forming a composite based on a dispersion of 2-60 wt. % of fluorinated particulate carbon material and a polyimide or polyimide precursor, and heating the dispersion to about 400.degree. C. at 65.degree.-200.degree. C./second.

The present invention relates to an improved pinless connector for use in microelectronics comprising an improved elastomer resin of polysiloxane and filler.

Process of making pinless connector

A roll for hot fusing having a coating comprising a cross-linked elastomeric random copolymer of dimethylsiloxane and diphenylsiloxane and three additives, (1) from 40 to 55% by weight of small zinc oxide particles, (2) from 5 to 10% by weight of small graphite particles and (3) from 1 to 5% by weight of ceric dioxide particles.
