摘要： A method of manufacturing a PCB comprising the steps of: forming through-holes in a substrate having releasing layers on front and back faces; filling conductive paste in the through-holes; removing the releasing layers and disposing metal foil on both faces of the substrate; and heat pressing them. A diameter of the through-holes is larger than that of corresponding holes formed on the releasing layers. According to the present invention, when the conductive paste is compressed, conductive paste protruding from the surface of the substrate is trapped at the edges of the through-holes. This configuration prevents short circuits with undesirable wiring patterns. So, an enough amount of the conductive paste can protrude from the surface of the substrate. Therefore, after the compression, stable electric connections inside the conductive paste and between the conductive paste and the metal foils are ensured, thus PCBs with superior reliability can be produced.

摘要： A PCB manufacturing method comprising: forming through holes in a substrate having parting layers formed on its front and back surfaces; filling the through holes with a conductive paste; removing the parting layers and arranging metal foils on the front and back surfaces of the substrate; and heating and compressing them to manufacture a PCB, wherein the through holes in the front and back surfaces of the substrate have diameters larger than those in the corresponding parting layers. When the conductive paste compresses, according to this method, the outflow of the conductive paste from the surface of the substrate stops at the boundary portions of the through holes so that the protrusion of the conductive paste from the substrate surface can be ensured while eliminating the short-circuit with other wiring patterns. Even after the substrate compression, therefore, the electric connections of the inside of the conductive paste and between the conductive paste and the metal foils can be improved to manufacture a highly reliable PCB.

摘要： A pre-preg sheet including a substrate and a resin impregnated in the substrate is provided. A first metal foil is placed on the pre-preg sheet to provide a laminated body. The laminated body is put in a heating device having a temperature maintained at a temperature close to a softening temperature of the resin. The laminated body is compressed at the temperature at a predetermined pressure. The first metal foil is bonded to the pre-preg sheet of the laminated body and hardening the resin, thus providing a circuit board. This method provides a stable resistance of a conductive paste filling a through-hole in the pre-preg sheet to be compressed at a small rate.
