Abstract:
A manufacturing method of circuit structure is described as follows. Firstly, a composite dielectric layer, a circuit board and an insulating layer disposed therebetween are provided. The composite dielectric layer includes a non-platable dielectric layer and a platable dielectric layer between the non-platable dielectric layer and the insulating layer wherein the non-platable dielectric layer includes a chemical non-platable material and the platable dielectric layer includes a chemical platable material. Then, the composite dielectric layer, the circuit board and the insulating layer are compressed. Subsequently, a through hole passing through the composite dielectric layer and the insulating layer is formed and a conductive via connecting a circuit layer of the circuit board is formed therein. Then, a trench pattern passing through the non-platable dielectric layer is formed on the composite dielectric layer. Subsequently, a chemical plating process is performed to form a conductive pattern in the trench pattern.
Abstract:
A process for fabricating a wiring board is provided. In the process, a wiring carrying substrate including a carry substrate and a wiring layer is formed. Next, at least one blind via is formed in the wiring carrying substrate. Next, the wiring carrying substrate is laminated to another wiring carrying substrate via an insulation layer. The insulation layer is disposed between the wiring layers of the wiring carrying substrates and full fills the blind via. Next, parts of the carry substrates are removed to expose the insulation layer in the blind via. Next, a conductive pillar connected between the wiring layers is formed. Next, the rest carry substrates are removed.

A circuit board including a first dielectric layer having a first surface and a second surface, a first circuit layer, a second dielectric layer, and a second circuit layer is provided. At least one trench is formed on the first surface, and the first circuit layer is formed on an inside wall of the trench. In addition, the second dielectric layer is disposed in the trench, and covers the first circuit layer. The second circuit layer is disposed in the trench, and the second dielectric layer is located between the first circuit layer and the second circuit layer. A manufacturing method of the circuit board is further provided.
Abstract:
A manufacturing process and an apparatus for printing imprint on defective board are provided. An automatic printing device is used for replacing operator, so as to reduce manpower and to increase the correctness and veracity of defect mark printing. The manufacturing process includes the following steps: first, an image sensor captures an image of a defect mark and transmits the image to a processing unit for data processing. Next, the data is compared, and an inkjet head is notified of the correct printing position to print ink on the customer identification mark of the printed circuit board.
Abstract:
A method for inspecting and mending defects of photo-resist is provided. It includes the following steps. First, a substrate having at least one film is provided. Then, a patterned photo-resist layer is formed on the film. Next, an optical inspection procedure is performed to inspect whether the patterned photo-resist layer has defects or not. If the patterned photo-resist layer has defects, the defects are classified into gaps and protrusions and then the gaps and the protrusions are positioned. If the patterned photo-resist layer has defects such as gaps, an ink-jet printing method, for example, is performed on the patterned photo-resist layer to fill the gaps up. If the patterned photo-resist layer has defects such as protrusions, a laser method, for example, is performed on the patterned photo-resist layer to remove the protrusions. So the defects of the patterned photo-resist layer can be mended.
