A method and apparatus for hydraulic high-pressure shaping of a printed circuit board

摘要

A device for hydraulic high-pressure shaping (1) a printed circuit board (2) is intended to be made of inexpensive. For this purpose the device is provided with an upper tool (6) and a lower tool (3), wherein at least one pressure-generating unit (7, 8) between the press ram (9) of a mechanical press and the upper tool (6) is arranged and the pressure medium of the pressure-generating unit (7, 8) as the action medium for the hydraulic deformation of the printed circuit board (2) is used, so constructed that the contact surfaces (14, 15, 18) of the tools (6, 3) directly on the board surface along the clamping region (13) which come to rest and the action medium is applied to the forming region (12) only by means of contact seal without additional sealing means sealing. Similarly, it is proposed a method.
