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.

A method for fabricating a circuit board is provided. A non-conductive material layer is provided on a core substrate, wherein the non-conductive material layer comprises a dielectric material and catalytic particles. A recessed circuit structure is then formed in the non-conductive material layer with a laser beam. Simultaneously, the catalytic particles in the recessed circuit structure are activated with aid of the laser. A buried conductive structure is then formed in the recessed circuit structure by chemical copper deposition methods.

A method for forming an embedded circuit is disclosed. First, a substrate including a dielectric layer is provided. Second, the dielectric layer is entirely covered by a dummy layer. Then, the dummy layer is patterned and a trench is formed in the dielectric layer at the same time. Later, a seed layer is formed to entirely cover the dummy layer and the trench. Next, the dummy layer is removed and the seed layer covering the dummy layer is removed, too. Afterwards, a metal layer is filled in the trench to form an embedded circuit embedded in the dielectric layer.

A selective metal surface treatment process of a circuit board, which has a solder mask and a multiple of selective metal treatment surface areas, wherein the solder mask covers the surface of the circuit board but exposes the selective metal surface treatment areas, is provided. The selective metal surface treatment process includes using a printhead to selectively print a resist on a selective metal surface treatment area, performing a surface treatment of the other selective metal surface treatment areas, and removing the resist. A selective metal surface treatment apparatus used for performing the selective metal surface treatment process of the circuit board is also provided. Through the present invention, unnecessary waste of the materials in the process is reduced and the processing time is shortened.
