ABSTRACT:
The invention defines a technique for assemblying all the parts of an electronic unit, for example a hand held calculator, directly on a plastic chassis without using individual printed circuit boards for various circuits of the calculator. Such parts of the calculator as the calculator chip, the display and the keyboard are all mounted on or formed on the plastic chassis in such a manner that only a cover has to be put over the plastic chassis to complete the calculator.
