ABSTRACT:
A printed wiring board comprising a main printed wiring board provided with a first wiring pattern, and an auxiliary flexible printed wiring board, provided with a second wiring pattern for modifying the first wiring pattern and bonded to the main printed wiring board so as to electrically connect the second wiring pattern to a desired part of the first wiring pattern. The auxiliary board may be affixed to the main board with a pressure-sensitive adhesive or thermosetting adhesive. The auxiliary board may be provided with marks for facilitating alignment, holes to provide access to the main board, a dummy pattern for preventing tears of the flexible auxiliary board, and a second dummy pattern to prevent warping from uneven stresses applied to the flexible auxiliary board by differences in thermal expansion of the auxiliary board and the pattern printed thereon. A method of making the board is also disclosed and claimed.
