Abstract: Adhesive tape composed of a sheet based on plasticized polyvinyl chloride and an adhesive dispersion based on styrene-acrylic acid derivative copolymers, comprising plasticizers which have migrated from the sheet into the adhesive.

Abstract: A method and structure of an electrical connector is provided for tuning the impedance of the terminals in the connector. The connector includes a dielectric housing having a plurality of terminal-receiving passages. A plurality of terminals are shaped from sheet metal material, with each terminal having a contact portion at one end and a terminating portion at an opposite end. The contact portion has a contact area which engages a mating terminal of a complementary mating connecting device. The contact portion, except for the contact thereof, or the tail portion, is selectively trimmed to a given size to vary the plate area of the contact portion or the tail portion to adjust the impedance of the terminal. This may be done by removing sections of the contact portion from the contact edges or by forming holes in the contact portions. Alternatively, to adjust impedance, a drive shoulder of the terminal may be located at a position to lengthen or shorten the contact portion or tail portion.
