    • The invention relates to a method of making a printed circuit (50), said printed circuit comprising a pattern of first parts (2, 2') and a pattern of second parts (1), the method comprising the steps of providing a dielectric substrate (10); forming on said substrate a metallic layer (12); printing on said metallic layer a first pattern matching the pattern of second parts using a first resist (A), said first resist resistant to a stripper solution (C); printing on said metallic layer a second pattern matching the pattern of first parts using a second resist (B), said second resist being strippable by said stripper solution; etching the metallic layer free of either said first and second resists; stripping said second resist using said stripper solution, while keeping said first resist as an electrical insulation layer. The invention also relates to the printed circuit (50) obtained therewith.
    • 本发明涉及一种制造印刷电路(50)的方法,所述印刷电路包括第一部分(2,2')的图案和第二部分(1)的图案,该方法包括以下步骤:提供介电基片 (10); 在所述基底上形成金属层(12); 使用第一抗蚀剂(A)在所述金属层上印刷与第二部分的图案相匹配的第一图案,所述第一抗蚀剂耐剥离剂溶液(C); 使用第二抗蚀剂(B)在所述金属层上印刷与第一部分的图案相匹配的第二图案,所述第二抗蚀剂可被所述剥离溶液剥离; 蚀刻不含所述第一和第二抗蚀剂的金属层; 使用所述剥离剂溶液剥离所述第二抗蚀剂,同时保持所述第一抗蚀剂作为电绝缘层。 本发明还涉及由其获得的印刷电路(50)。
