An arrangement for providing improved efficiency in laser bonding is disclosed. In particular, at least one piece part in the arrangement is formed to include means for concentrating a beam of radiation at a predetermined attachment location (or several locations). The concentrating means may be in the form of an aperture, such as a conical or parabolic opening, which will concentrate the radiation to the area of interest. Alternatively, if the piece part is transparent to the wavelength of the radiation, the concentrating means may be in the form of a lens or grating formed on the surface of the piece part. |
