Abstract:
PURPOSE: A carrier member for manufacturing a substrate as an insulating layer and a circuit pattern of a coreless substrate and a method for manufacturing a substrate using the same are provided to save the manufacturing cots of a coreless substrate. CONSTITUTION: Metal layers(120) are placed on both sides of an insulating layer(110). A first hole(130) penetrates an edge of the insulating layer in a thickness direction. A fixing member(140) is inserted into the first hole and fixes two insulating layers. A base substrate is placed between the insulating layers. A second hole is formed on the base substrate. The second hole corresponds to the first hole.

PURPOSE: A carrier for manufacturing a printed circuit board and manufacturing method thereof are provided to configure a carrier by a part of a printed circuit board, thereby preventing cost loss due to the manufacture of the carrier. CONSTITUTION: A base member functions as a core layer. The base member includes a two-layered metal layer(120) and an insulating layer(110). An adhesive member(200) adheres the two-layered metal layer. The length of the adhesive member is thicker than the thickness of the base member to form a step toward the insulating layer. The adhesive member comprises a protrusion in the thickness direction of the base member.

Abstract:
A method for manufacturing a printed circuit board is provided to reduce the number of manufacturing processes and a manufacturing cost by forming a pattern and a via in a conductive material forming process. A circuit pattern and a via land are formed in an inner layer substrate(S100). An insulating material is laminated on the inner layer(S200). The via hole is formed to pass through the inner layer substrate and the insulating material(S300). A seed layer is formed in an inner wall of the insulating material, the inner wall of the via hole, and the inner wall of the blind via hole(S400). A plating resist is formed in the seed layer(S500). The conductive material is formed in the surface of the seed layer, the inner part of the blind via hole, and the inner part of the via hole(S600). The plating resist is removed(S700).
Abstract:
A method of manufacturing a printed circuit board is provided to increase a bonding strength between an insulation layer and a circuit pattern by forming an electrolyte copper plating layer on a conductive carbon material. An electroless copper plating layer(106) is formed on an insulation layer(102). A dry film(108) is applied on the electroless copper plating layer and a circuit pattern is formed by using exposure and developing processes. The electroless copper plating layer, which is exposed from region for a circuit pattern, is removed. A seed layer is formed through a conductive carbon material on the insulation layer from which the electroless copper plating layer is removed. An electrolyte copper plating layer is formed on the conductive carbon material. The dry film is removed and the electroless copper plating layer is removed from the removed portion of the dry film.

Abstract:
A printed circuit board and a method for manufacturing the same are provided to realize a fine circuit below a line/space of 10/10 without an additional facility by increasing the degree of freedom for securing a pattern plating thickness. A method for manufacturing a printed circuit board includes the steps of: preparing the printed circuit board having a via hole to conduct between layers; forming a metal seed layer(105) on the printed circuit board including the via hole; forming a first metal plating layer(106) by performing an electrolyte panel plating on the printed circuit board for a via charging at a first static current density and a first inverse current density; etching the metal seed layer and the metal plating layer to make a total thickness of the metal seed layer and the metal plating layer of 0.5 to 2um; forming a second metal plating layer(108) by performing electrolyte pattern plating on the etched printed circuit board for a circuit pattern thickness plating at a second static current density and a second inverse current density; and forming a circuit pattern(109) by removing the first metal plating layer and the metal seed layer of a portion where the second metal plating layer is not formed.
Abstract:
A chaos signal generating apparatus and method are provided to solve a problem of the related art that when value of a passive element is changed by a certain degree according to a change in a process, a chaos signal may not be generated at a UWB(Ultra Wide Band) operation frequency. A PN(Pseudo Noise) signal generating unit(51) is configured in a digital logic type and generates a pseudo-random signal in a digital form with a certain frequency. A VCO(Voltage Control Oscillator)(52) generates a clock signal of a certain frequency. A mixer unit(53) mixes the pseudo-random signal with the clock signal to generate a chaos signal and output it. A BPF(Band Pass Filter)(54) filters the chaos signal outputted from the mixer unit(53) so as to become a chaos signal of a desired band and outputs it.
Abstract:
PURPOSE: A plating device is provided to increase the temperature of a plating object by indirectly heating the plating object as only a plating solution adjacent to the plating object is heated by a heater. CONSTITUTION: A plating device(100) comprises a plating bath, an anode(130), a cathode(120), and a heater(140). A plating solution is received in the plating bath. The anode is arranged inside the plating bath. The cathode is electrically connected to the plating object arranged inside the plating bath. The heater heats the plating solution adjacent to the plating object.
