Flexible flat cable with insulating layer having distinct adhesives on opposing faces

1. A flexible flat cable comprising:

(a) a first insulating layer;

(b) a second insulating layer disposed generally parallel to the first insulating layer;

(c) a first adhesive disposed between the first and second insulating layers;

(d) a plurality of conductors disposed between the first and second insulating layers;

(e) a second adhesive disposed along an outer surface of the first insulating layer, wherein the second adhesive has a higher cure temperature than the first adhesive; and

(f) a first liner removably attached to the second adhesive.

2. The flexible flat cable of claim 1 further comprising:

(a) a third adhesive disposed along an outer surface of the second insulating layer; and

(b) a second liner removably attached to the third adhesive.

3. A method of attaching a flexible flat cable to a substrate, comprising:

providing a flexible flat cable, the cable comprising:

a plurality of conductors disposed between a first and a second insulating layer;

a first adhesive disposed between the first and second insulating layers;

a second adhesive disposed along an outer surface of the first insulating layer, wherein the second adhesive has a higher cure temperature than the first adhesive; and

a first liner removably attached to the second adhesive;

removing the first liner; and

applying the flexible flat cable to a substrate.

4. Vehicle headliner comprising:

(a) a headliner layer;

(b) a first insulating layer attached to the headliner layer with an exterior adhesive;

(c) a second insulating layer attached to the first insulating layer with an interior adhesive, wherein the exterior adhesive has a higher cure temperature than the interior adhesive; and

(d) a plurality of conductors disposed between the first and second insulating layers.
