PRINTED CIRCUIT BOARD LAYOUT This layout provides the horizontal printed circuit board layout as viewed from the top side of the PC board. Turning end to end will result in a different pin location. However, the dimensional relationship will remain the same. Lightable Modules–per drawing below. This drawing indicates the layout to be used for a 6 button module with light sources mounted two ways: the lamps for the upper 3 buttons are mounted from the top or component side of the board, and the lamps for the lower 3 buttons are mounted by the easy replacement method. (See also Light Source and Lamp Mounting.) Light sources, when mounted from the top side of the board, must be mounted before the keyboard modules; when mounted, lamp should extend no more than .250" (6,35 mm) above the board.
