Terminal blades mounted on flexible substrates

An electronic device, comprising:

• a flat flexible dielectric substrate having a generally round hole of a given diameter;
• a ductile conductive film on the substrate in an area at least around said hole;
• a generally flat terminal blade of sheet metal material and having a pin portion formed integrally therewith and projecting therefrom into the hole in the substrate in contact with the conductive film, whereby the flat terminal blade is generally parallel to the flat flexible substrate, the cross-dimension of the pin portion being greater than the diameter of the round hole;
• and
• wherein the difference between the cross-dimension of the pin portion and the diameter of the round hole is on the order of 5% to 50% of the diameter of the hole.
