    • PROBLEM TO BE SOLVED: To prevent the short-circuiting of a circuit without fail by expanding the range of choice with respect to the material quality of a primary base and the material quality of the resin mask of a secondary base. SOLUTION: As for the shape of a primary base 1, a circuit forming side 11 is made into a convex state, while a circuit non-forming side 12 is made into a concave state. Further, the height difference between them is made into 0.05 mm and the angle of side walls 13 and 14 which connect the circuit forming side and a circuit non-forming side is made into 90°. Palladium catalyst solution is immersed in a bath with water depth of 500 mm for 5 minutes by liquid temperature of 40°C for applying catalyst. Then, a resin mask 3 is dissolved and removed so as to perform electroless plating. As a result, the catalyst liquid is permeated only in the range of the part with long creepage distance, namely till both the side walls 13 and 14 which can stop the permeation of the catalyst. Accordingly, it is made possible to prevent the generation of the short-circuiting between electric conductive layers 50, that is, between circuits. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:通过扩大相对于一次基体的材料质量的选择范围和二次基体的树脂掩模的材料质量来防止电路短路。 解决方案:对于初级基座1的形状,电路形成侧11被制成凸状,而电路非成形侧12被制成凹状。 此外,它们之间的高度差为0.05mm,将电路形成侧和非电路侧连接的侧壁13和14的角度设为90°。 钯催化剂溶液在40℃的液温下浸入水深500mm的浴中5分钟,用于施加催化剂。 然后,将树脂掩模3溶解除去以进行无电镀。 结果,催化剂液体仅在具有较高爬电距离的部分的范围内渗透,即直到两侧壁13和14都能够阻止催化剂渗透。 因此,可以防止在导电层50之间,即在电路之间产生短路。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a printed-wiring board made of metal coating polyimide in a two-layer configuration of which an insulating resistance value cannot easily fluctuate.
      SOLUTION: A conductive metal laminated via a sputtering metal layer is formed on at least one surface of an insulating film, the sputtering metal layer and a conductive metal layer are selectively removed by an etching method for forming a wiring pattern. Then the laminated film is treated by a first liquid that can dissolve Ni contained in the sputtering metal layer, and is treated by a second treatment liquid that can dissolve Cr contained in the sputtering metal layer for removing the sputtering metal layer in the insulating film. A sputtering metal remaining on the surface layer of the insulating film on which the wiring pattern is not formed is removed with the surface layer of the insulating film. The printed-wiring board is formed so that the thickness of the insulating film at a portion in which no wiring pattern is formed becomes thinner by 1-100nm than that of the insulating film in which the wiring pattern is formed.

    • 要解决的问题:提供一种绝缘电阻值不能容易波动的双层结构的由金属涂层聚酰亚胺制成的印刷电路板。 解决方案:通过溅射金属层层压的导电金属形成在绝缘膜的至少一个表面上,通过用于形成布线图案的蚀刻方法选择性地去除溅射金属层和导电金属层。 然后,通过可以溶解溅射金属层中所含的Ni的第一液体来处理层压膜,并且通过能够溶解溅射金属层中包含的Cr的第二处理液来处理绝缘膜中的溅射金属层。 绝缘膜的表面层除去残留在绝缘膜的未形成布线图案的表面层上的溅射金属。 印刷电路板形成为使得绝缘膜在不形成布线图案的部分的厚度比形成有布线图案的绝缘膜的厚度减薄1-100nm。 版权所有(C)2005,JPO&NCIPI
