The present invention relates to a method for assembling a circuit carrier with a housing component and furthermore to an optical unit for emitting andor receiving radiation that is fabricated using this particular method of assembling and aligning the circuit carrier with the housing component. An example method may include, filtering, in a receiver, a received inter-symbol correlated signal to generate a filtered ISC signal. A first pair of opposed surfaces is formed within the housing. 5 times that by plain knitting or thicker which is equal to a thickness obtained by rib knitting. The configuration manager application then produces a report indicating the objects that satisfy the search criteria.
