Abstract
The present invention relates to an improved pinless connector for use in microelectronics comprising an improved elastomer resin of polysiloxane and filler.
Claims3
A process for making an electrical connector comprising a dielectric composition having first and second opposing surfaces and a plurality of electrically conducting wires having a diameter less than 10 mils extending from the first to the second opposing surface of the electrical connector, the dielectric composition comprising a crosslinked polysiloxane composition having a tensile strength greater than 170 psi, the process comprising the steps of:
- (a) disposing uncrosslinked polysiloxane composition having a viscosity less than 5500 centipoise around a plurality of unsupported electrically conducting wires bonded to a sacrificial substrate, said uncrosslinked polysiloxane composition comprising (i) about 70 to 90 weight % of random copolymer of dimethylsiloxane and diphenylsiloxane and (ii) about 10 to 30 weight % of filler comprising zinc oxide and a lanthanide oxide;
- (b) hydrosilation crosslinking of the polysiloxane composition and
- (c) removing the sacrificial substrate.
