发明名称 Method for producing a rewiring printed circuit board
摘要 The invention relates to a method for producing a rewiring printed circuit board with a substrate wafer having passage connections between a first and a second surface. One embodiment of the method comprises applying and patterning masking layers on the first and the second surfaces, thereby uncovering a first contact location on the first surface and a second contact location on the second surface; applying a protective layer to the second surface in order to protect the corresponding masking layer and the second contact location during subsequent method steps; applying a first conductor structure to the first surface, the first conductor structure on the first surface covering the first contact location; removing the protective layer on the second surface; and applying a second conductor structure to the second surface, the second conductor structure on the second surface covering the second contact location.
