Abstract: A double-sided flexible circuit board includes a flexible substrate, a first circuit layer, a second circuit layer, an insulating protection layer and a plurality of through circuit lines. The first and second circuit layers are located on a top surface and a bottom surface of the flexible substrate, respectively. The insulating protection layer covers a supporting line of the second circuit layer such that the supporting line is located between the flexible substrate and the insulating protection layer. The insulating protection layer can provide electrical insulation to the supporting line of the second circuit layer to avoid short circuit conditions of the double-sided flexible circuit board during test.

Abstract: A circuit board tape includes substrate units each including a sprocket-hole region, a layout region and a joining mark. There are odd and more than three sprocket holes on the sprocket-hole region. An imaginary line extended from the joining mark is extended to between a first layout and a second layout located on the layout region. The amount of the sprocket holes between the imaginary lines of the adjacent substrate units is odd. The circuit board tape is cut along the imaginary lines of the different substrate units so as to remove the defective substrate unit from the circuit board tape and divide the circuit board tape into a front tape and a rear tape. After joining the front and rear tapes, the region where a first layout on the front tape and a second layout on the rear tape are located is defined as a combined layout region.

Abstract: A double-sided flexible circuit board includes a flexible substrate, through circuit lines, first circuit lines and second circuit lines. The first circuit lines are formed on a top surface of the flexible substrate and each includes a first segment, a bent segment and a second segment. One end of the first segment is connected to a first connection end of one of the through circuit lines. Both ends of the bent segment are connected to the other end of the first segment and one end of the second segment, respectively. A second distance between the adjacent second segments is greater than a first distance between the adjacent first segments. The second circuit lines are formed on a bottom surface of the flexible substrate and each is connected to a second connection end of one of the through circuit lines.

Abstract: A flexible circuit board includes a flexible light-permeable carrier, a circuit layer, a mark and a stiffener. The circuit layer and the mark are located on a top surface of the flexible light-permeable carrier. A predetermined area and a stiffener mounting area corresponding to each other are defined on the top surface and a bottom surface of the flexible light-permeable carrier, respectively. The mark is opaque to create a shadow mark having a longitudinal reference side and a lateral reference side on the bottom surface. The stiffener is adhered to the stiffener mounting area defined on the bottom surface by aligning with the longitudinal reference side and the lateral reference side of the shadow mark.

Abstract: In a flip chip package, lines, an identification line and a dummy line are provided on a first surface of a light-transmissive carrier, and a supportive layer is disposed on a second surface of the light-transmissive carrier. Bumps and an identification bump of a chip are bonded to the lines and the identification line, respectively. Shadows of the dummy line, the identification line and the identification bump which are projected on the second surface are visible from an opening of the supportive layer. The shadows can be inspected through the opening so as to know whether the bumps are bonded to the lines correctly.
