Abstract: Method a method for the opening of a plastic-housed electronic module. Previously, the electronic module can be only inadequately protected during the opening of the plastic housing, so that the electronic module is damaged during the opening. According to the new method, during the opening of the housing by a laser, the electronic module is protected from the effects of the laser beam by means of an end point signal detection and a protective layer. Thereby, after the opening of the housing, electrical measurements can be carried out on the electronic module.
