Method for producing an optical or electronic module provided with a plastic package

A method for producing an optical or electronic module provided with a plastic package, comprising:

• providing at least one optical or electronic component, the component having an operative region, via which it is in operative connection with the surroundings in the finished module,
• encapsulating the at least one component with at least one polymer compound to form the plastic package,
• after the encapsulation, ascertaining a position of the component by direct measurement of the position of the component in coordinates of a three-dimensional system of coordinates with respect to a system of coordinates external to the module, wherein the direct measurement of the position of the component is ascertained by means of an ultrasonic measuring device,
• aligning the component with respect to a device for partially removing the polymer compound or alignment of such a device with respect to the component, the alignment taking place with allowance for the directly ascertained position of the component, wherein the device for partially removing the polymer compound is aligned with respect to the system of coordinates external to the module,
• partially removing the polymer compound using the device from the outside in such a way that the polymer compound between the operative region of the component and the outer side of the plastic package is at least partially removed.
