Now...I have a better, quickest, easy, tek...you saw that two layers ? "is made of a kind of laminated material that has insulation to resist heat, electrical properties, metal foil, and adhesive. Usually, conductive bumps allow conductivity between the flexible circuit board and another circuit board by pressing the bumps to pads with pressure. This creates electric flow between the systems. Flexible circuit boards are known for their lightness, thinness, flexibility, and convenience in size..."Pi, Copper, Gold Plating Single Layer Flexible Circuit Board FPC (MIC0467)
