摘要： A multi-layer printed wiring board in which an internal board has a wiring pattern on both sides. Two conductive plates for establishing respective voltage planes are formed with a pattern of grooves to match the wiring pattern of the internal board. The internal board is then sandwiched to the two sides of the conductive plates, with the grooves registering with the wiring pattern, and with intermediate insulating layers. Further, insulated wiring patterns are formed on the exterior sides of the conductive plates together with through-holes through the assembly.

摘要： An apparatus for plating a printed circuit board including a non-through hole for connecting between a surface conductive layer and an interlayer wiring layer has a jig, a vessel, a supporting body carrying the jig for causing it to vibrate and swing in a plating liquid contained in the vessel, and a vacuum pump connected to the vessel for exhausting the air in the vessel thereby enhancing removal of bubbles in the non-through hole. A method of plating a printed circuit board includes the step of reducing the pressure inside the vessel simultaneously with the printed circuit board being subjected to the vibration and swinging actions thereby to remove a bubble existing inside the non-through hole. The removal of the bubble makes it possible to have a uniform plating film formed in an inner wall of the non-through hole and ensures the reliable electric connection to be established through the non-through hole between a surface conductive layer and interlayer conductive layers.

摘要： A laminated board in which each of prepreg sheets is sandwiched between an internal printed wiring board which is provided with wirings and each of external printed wiring board which is provided with wirings on the outermost surface thereof is formed with through-holes by drilling. A thin copper plating layer is formed on the surfaces of the laminated board including the inner wall of the through-hole. Then, an alkali-soluble photoresist film is selectively formed on the surface of the thin copper plating layer and a thick copper plating layer is formed. The thin copper plating layer is removed by using the thick copper plating layer as a mask to forme through holes and wirings. The through holes and wirings can be thus formed without using the additive process. Environmental pollution due to use of organic solvents can be prevented by avoiding the use of an organic solvent-soluble resist film having a strong resistance to alkalis.
摘要翻译：在其中每个预浸料片被夹在设置有布线的内部印刷线路板和在其最外表面上设置有布线的每个外部印刷线路板之间的每个预浸料片通过钻孔形成有通孔。在包括通孔的内壁的层压板的表面上形成薄的镀铜层。然后，在薄铜镀层的表面上选择性地形成碱溶性光致抗蚀剂膜，形成厚铜镀层。通过使用厚铜镀层作为掩模去除薄铜镀层，以形成通孔和配线。因此，可以不使用添加剂来形成通孔和布线。通过避免使用耐碱性强的有机溶剂可溶性抗蚀剂膜，可以防止使用有机溶剂造成的环境污染。
