摘要： A fluxgate sensor is integrated in a printed circuit board. The fluxgate sensor has two bar-type (or rectangular-ring shaped) soft magnetic cores to form a closed magnetic path on a printed circuit board and an excitation coil in the form of a metal film is wound around the two bar-type soft magnetic cores either in a united structure that winds the two bar-type soft magnetic cores altogether, or in a separated structure that winds the two bar-type soft magnetic cores respectively, both in a pattern of number ‘8’. A pick-up coil is mounted on the excitation coil, either winding the two bars altogether, or respectively, in a solenoid pattern. The fluxgate sensor integrated in the printed circuit board can be mass-produced at a cheap manufacturing cost. The fluxgate sensor also can be made compact-sized, and at the same time, is capable of forming a closed-magnetic path. As a result, flux leakage is minimized, and the fluxgate sensor has a high sensitivity as it detects the magnetic field through a variable driving.

摘要： A method for manufacturing a printed circuit board is disclosed. When a metal is plated on an upper board to form a circuit, bonding fingers for being bonded with a semiconductor chip are prevented from being electroplated with a metal. That is, a slot with an ink layer formed therein is formed in each of a plurality of boards. Then window regions of different sizes are defined, and a working is carried out on the portion where the slots are not formed. That is, the copper clad laminates are subjected to a working to form slots, and an ink layer is formed within each of the slots. In this manner, during the plating of the upper face of the printed circuit board, the metal is prevented from intruding into the window region, thereby preventing the formation of a short circuit.

摘要： A method for manufacturing a build-up multi-layer printed circuit board is disclosed in which a YAG laser is used upon the formation of a via hole in the multi-layer printed circuit board, such that it can have the following advantages: the manufacturing process would become simple; the component packaging density and freedom for the design of the board would be improved; and a high speed of signal process would be ensured. The method for manufacturing a build-up multi-layer printed circuit board includes the steps of: forming a first printed circuit pattern on a copper clad laminate (CCL) by applying a general photo-etching process, the CCL having a copper foil on the one face thereof; stacking a resin-coated (on one face) copper foil (RCC) on the CCL with the first printed circuit pattern formed thereon, and heating and pressing this structure; irradiating a YAG laser to the board with said RCC stacked so as to form a via hole at a predetermined position by removing said RCC; carrying out an electroless and electro copper plating on the board with the via hole formed therein to form a plated layer; and forming a second printed circuit pattern on said plated layer to electrically connect the layers on which the first and second printed circuit patterns are formed.
