Abstract: An improved mounting arrangement and method of assembly provides for mounting parts on both chassis and board, then mating the two before soldering by means of a twist-tab-and-slot arrangement. The conformation and dimensions of the tab and slot prevent warpage during soldering, enabling the use of the chassis as a board carrier in the wave soldering process.

Abstract: A chassis for supporting a printed circuit board and other components is captivated between two plastic housing portions in a suspension mode. The housing provides support for the entire unit, there being no direct support to the chassis or printed circuit board or associated components. The chassis is formed with projecting tabs which are captivated between bosses formed on the upper and lower parts of the housing. A screw penetrates the boss of the upper portion and the chassis tab, then threads into the boss of the lower portion. Wedge bosses formed in the back walls of the housing bias the chassis into alignment with the rear of the housing when the housing parts meet and provide support to the chassis when interconnecting cables are attached. No individual components, other than the speaker, are fixed to either housing part.
