    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 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: A storage device of the present invention is provided to store flexible circuit packages, each of the flexible circuit packages includes an electronic component and two circuit portions warped at both sides of the electronic component, respectively. The storage device includes a first carrier and a second carrier. The first carrier includes first accommodation elements provided for placement of the flexible circuit packages, and the second carrier includes a first press portion and a second press portion. As the second carrier is placed on the first carrier, the first and second press portions are provided to press the two circuit portions warped upwardly toward the second carrier so as to reduce the warpage of the two circuit portions.

    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 circuit board includes a substrate having a through hole, a circuit layer, a first measurement mark and a second measurement mark. According to the first and second measurement marks, an electronic detection device can measure a first distance between a first edge of the through hole and the first measurement mark and a second distance between a second edge of the through hole and the second measurement mark to determine whether the through hole has an undesired size or shift.
