FORMING CONTACT ARRAYS ON SUBSTRATES

摘要

An electrical device (10) includes a flat flexible insulating substrate (12) having an opening (14) therethrough. A flat conductive terminal (16) is deposited on one side (12a) of the substrate at the opening. A portion (20) of the terminal is formed through the opening (14) so that the terminal has opposite ends at opposite sides of the substrate. One end (20) of the terminal forms a contact portion thereof, and an opposite end (18) of the terminal forms a land portion for receiving a solder ball (22).
