Disclosed is a method and a device for checking the quality of a crimping of a specified cable with a specified contact sleeve using a sensor system for measuring a force and a displacement of a device for the actuation and/or force application of a crimping unit and using an electronic analysis system. In the method a force/displacement curve is detected during the crimping process and is displayed on a screen, wherein the method has the following steps: a stored reference model is displayed on the screen together with the detected force/displacement curve, said reference model having a first and a second envelope curve which define a tolerance range;—comparing the force/displacement curve with the reference model, thereby ascertaining whether the force/displacement curve lies in the tolerance range; and—arriving at a conclusion regarding the quality of the crimping from the comparison.

A crimping apparatus comprising a press module connected with a pressing mold, a translation module, and a pressure control module is disclosed. The press module generates an action force on the pressing mold through a fluid. The translation module is coupled to the press module for driving the press module to move toward a flexible printed circuit having two isolated circuit layers such that one circuit layer is pressed to crimp to the other circuit layer, wherein the pressure control module adjusts the pressure within the press module to maintain a constant force on the pressing mold whereby the pressing mold can generate a constant stress acting on the flexible printed circuit during the crimping process. In addition, the crimping apparatus can be adapted in a roll-to-roll process for crimping two isolated circuit layers of each flexible printed circuit unit arranged on the roll.
