METHOD FOR PRODUCING A FLEXI-RIGID PRINTED CIRCUIT BOARD AND FLEXI-RIGID PRINTED CIRCUIT BOARD

摘要

The invention relates to a method for producing a flexi-rigid printed circuit board, at least one rigid zone (1, 17, 18) of a printed circuit board being connected via a layer of non-conducting material or a dielectric layer (13, 15) to at least one flexible zone (7) of the printed circuit board, the at least one rigid zone being connected to the flexible zone (7) of the printed circuit board, the rigid zone (1) of the printed circuit board then being cut through and a connection between the separate, rigid partial zones (17, 18) of the printed circuit board being established via the flexible zone (7) that is connected thereto. According to the invention, the connection between the at least one rigid zone (1, 17, 18) of the printed circuit board and the at least one flexible zone (7) of the printed circuit board is established by bonding prior to cutting the rigid zone. The invention also relates to a flexi-rigid printed circuit board of the above type which allows increased registration accuracy and is easy to produce and has a reduced layer thickness of the connection (15) between the at least one rigid zone (1, 17, 18) and the flexible zone (7) of the printed circuit board.
