Abstract
A method for assembling the rubber domes into a housing of upper casing of a keyboard is provided. The upper casing is in substantially form of shell shape and defines a bottom surface and a top surface. The upper casing includes a multiple of housings distributed over a central portion of the bottom surface. Each housing receives one rubber dome. The method includes the steps of pouring a plurality of rubber domes over the bottom surface of the upper casing; shaking the upper casing such that one rubber dome is disposed into one corresponding housing while a number of leftover rubber domes are not received in any one of the housings; engaging a membrane circuit sheet with the central portion of the bottom surface; flipping the upper casing over such that the leftover rubber domes not covered by the membrane circuit sheet are cleaned up.
