Disclosed is a magnetic excitation coil structure including a magnetic coil sheet formed of a thin film and rolled as a cylindrical body with a hollow hole, and an insulation layer covering the outer surface of the cylindrical body formed by the magnetic coil sheet for protection. The magnetic coil sheet includes a flexible substrate, a dielectric layer attached to the flexible substrate, and a plurality of patterned circuit layers embedded in the flexible substrate and in contact with the dielectric layer. Each patterned circuit layer is separate, and the upper surfaces of the patterned circuit layers and the upper surface of the flexible substrate form a co-plane. The magnetic coil structure provides an electrical function of coil, which is enhanced by the patterned circuit layer due to its high aspect ratio of the electrical circuit, thereby greatly increasing the whole magnetic flux and electromagnetic effect.

Disclosed is a modified magnetic coil structure. A substrate, at least one circuit pattern layer and a permeability enforced ring are included. The substrate is formed of an electrical insulation material, and has a through hole. The circuit pattern layer is formed of an electrically conductive material and configured in the substrate to surround but not contact the through hole. The permeability enforced ring is formed of a high permeability material and provided in the through hole so as to fully cover a sidewall of the through hole. The permeability enforced ring and the substrate form two co-planes in an upper horizontal plane and a lower horizontal plane of the modified magnetic coil structure, respectively. Therefore, the present invention employs the permeability enforced ring to greatly increase magnetic flux density to form a high permeability device, thereby improving the electromagnetic effect and properties of the magnetic coil.

A multilayer substrate structure includes a first plastic sheet, a second plastic sheet, a first circuit pattern layer, a second circuit pattern layer, and an interlayer connection pad. A first connection plug connected to the interlayer connection pad fills in a first opening of a first plastic sheet and is connected to a first connection pad of the first circuit pattern layer. A second connection plug fills a second opening of the second plastic sheet and is connected to a second connection pad of the second circuit pattern layer such that the second circuit pattern layer is electrically connected to the first circuit pattern layer via the interlayer connection pad. Therefore, even if there is little offset, it is possible to overcome the alignment tolerance and assure electrical connection between the circuit layers as desired.

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.

Disclosed is a circuit board structure, including the first, second and third metal layers sequentially stacked on the substrate from bottom to top and formed by the sputtering process, the chemical plating process and the electroplating process, respectively. The substrate includes the stop layer and the resin layer stacked on the stop layer. The stop layer includes a pattern having at least one contact region, which is not covered by the resin layer. The first, second and third metal layers have an etched circuit pattern, respectively, and each of the etched circuit patterns is provided out of the corresponding contact region and aligned to each other to expose part of the resin layer. The etched circuit pattern is used for electrical connection. Since the first metal layer provides excellent surface properties, the second and third metal layers are well fixed and more stable.

The etched circuit pattern has a line width/pitch less than 10 m for fine line width/pitch.


A method for manufacturing a circuit board with a buried element having high density pin count, wherein a micro copper window formed in a first circuit by patterned dry film electroplating is easily controlled less than 50 m so that the micro conduction holes formed after the laser drilling each has a diameter greatly shrunk less than 50 m so as to highly increase density of the micro conduction holes, thereby facilitating in burial of the buried element with the high density pin count. Additionally, by disposing the micro conduction holes in the same elevation, optically aligning a fixing position for the buried element can be controlled precisely.
