摘要： A film-peeling apparatus is adapted to peel a protective film on a surface of a substrate. The surface of the substrate has a bare area which is not covered by the protective film. The film-peeling apparatus includes a punching member, a connector connected to the punching member, and a controller. The controller is configured for driving, through the connector, the punching member to punch at predetermined positions nearby or on a first edge of the protective film adjacent to the bare area.

摘要： An ameliorated compound carrier board structure of Flip-Chip Chip-Scale Package has the insulating layer between the carrier board and the substrate in the prior art replaced by an anisotropic conductive film or materials with similar structure. The anisotropic conductive film has conductive particles therein to replace the conductive openings on the insulating layer in the prior art. When compressing the substrate onto the carrier board, the bottom surface of the second electrode pads are compressing the corresponding conductive particles on the second electrical contact pads, causing which to burst, therefore forming high-density compressed areas that conduct the second electrode pads and the second electrical contact pads; the conductive particles outside the high-density compressed area are not burst, forming an insulating film between the substrate and the carrier board; in other words, the anisotropic conductive film provides conduction in a Z direction. The structure can avoid the inaccuracies of distance and size of the conductive openings and the inaccuracy of the contact between the second electrode pads and the second electrical contact pads.

摘要： A multi-layer circuit board includes a first circuit board, multiple conducting blocks, a second circuit board, and multiple conducting recesses. The first circuit board has a first conductor layer formed thereon. The conducting blocks are mounted on the first circuit board and electrically connected to the first conductor layer. The second circuit board has a second conductor layer mounted thereon and facing the first circuit board. The conducting recesses are formed in the surface of the second circuit board. Each conducting recess has a conducting layer electrically connected to the second conductor layer. When the conducting blocks are mounted in the conducting recesses, the first conductor layer and the second conductor layer are electrically connected through the conducting blocks and the conducting recesses. As can be separated from the first circuit board for test of the two conductor layers, the yield of the second circuit board is enhanced.

摘要： A method of manufacturing a multilayer substrate structure includes the steps of pre-treatment, pressing and post-treatment. A carrier plate provided with a circuit pattern layer is pressed against a plastic sheet. An interlayer connection pad is formed by drilling and filling the lower surface of the plastic sheet. The carrier plate, the plastic sheet, another plastic sheet and another carrier plate with a circuit pattern layer are pressed together, and then drilled/filled to form a multilayer stacked structure such that the two circuit pattern layers are indirectly and electrically connected to the interlayer connection pad, respectively. Therefore, it is possible to overcome the problem due to alignment tolerance by using the interlayer connection pad wider than alignment tolerance, and stacking the circuit layers, each having much finer line and smaller pitch.
