Sony patents flexible circuit with holes for easier manufacturing
Sony describes a method for making electronic components on a thin, insulating plastic film. The design includes a metal layer on one side and a hole, or via, that goes all the way through the film to connect the metal to the other side.
In the filing’s own words
Provided is a compact electronic apparatus having an excellent manufacturability. The electronic apparatus includes an insulating film substrate, a thin film device, and a through via. The insulating film substrate includes a first main surface and a second main surface that is on a side opposite to the first main surface. The thin film device includes a metal layer formed on the first main surface of the insulating film substrate. The through via extends from a first part within the metal layer to pass through the insulating film substrate and reach at least the second main surface.
What exactly they claim (claim 1)
1. An electronic apparatus comprising: an insulating film substrate including a first main surface and a second main surface that is on a side opposite to the first main surface; a thin film device including a metal layer formed on the first main surface of the insulating film substrate; and a through via that extends from a first part within the metal layer to pass through the insulating film substrate and reach at least the second main surface.
