Abstract

In fitting components such as resistors, delay lines, etc. into a circuit board which is to be one of several mounted in stacked or superimposed relation, the height of the individual components must be uniform or at least within certain tolerances so that the boards may be closely fitted in this relation.

Height Gauge

In fitting components such as resistors, delay lines, etc. into a circuit board which is to be one of several mounted in stacked or superimposed relation, the height of the individual components must be uniform or at least within certain tolerances so that the boards may be closely fitted in this relation.

In the drawing a simple height gauge is provided. The height gauge includes a slide block 10 reciprocable in a track 11 mounted on a base 12. An upstanding projection 13, on the slide block 10, having a plurality of apertures 14 therein permits leads of a component 15 to be placed therethrough. The slide block 10 is movable upward in the track 11 until it registers with a slide stop 16. As the block comes into registration with the slide stop 16 the component 15 contacts a pivotably mounted indicator plate 17 against which is urged the input rod 18 of a standard dial indicator 19. In this manner, knowing the zero position of the block and setting the dial indicator, repeated measurements will indicate deviations in height of components. Alternately, the slide block 10 may be fixed to the base 12, as by the screw 20, and the fixture used as a snap gauge for measuring parts held, for example, in a carrier strip.
