Abstract

A technique is described whereby a single nine-stroke snapping tool provides the ability to separate laminates into nine individual substrates. The tool is an improvement over other methods, such as single separation, in that it provides fast and accurate substrate separation and eliminates the need for any sizing operations.

Single-Stroke Nine-Segment Substrate Snapping Tool

A technique is described whereby a single nine-stroke snapping tool provides the ability to separate laminates into nine individual substrates. The tool is an improvement over other methods, such as single separation, in that it provides fast and accurate substrate separation and eliminates the need for any sizing operations.

A pre-grooved substrate L, as shown in Fig. 1, is positioned between bottom half A and top half B. Both halves contain nine individual pads C which are spring loaded, except center pad D which is solid. Each pad is numbered starting with the lower left position as number 1, proceeding counter-clockwise to number eight. The center pad is not numbered. Pads 2 and 6 have stop blocks E fixed to limit travel relative to base F. Pads 4 and 8 utilize stronger compression springs than the other pads so as to control the sequence of snapping.

Top half B has a similar configuration as bottom half A and is positioned onto two shafts G. Top half B is equipped with two ball bushings H, as shown in Figs. 1 and 2, which allow top half B to smoothly and accurately move up and down. An operator loads scored substrate L into the top section of bottom half A, on top of its pads. Top half B is lowered and rests on the substrate. Force lever I is pivoted at K such that when force is applied to lever I, all nine segments on scored substrate L will separate. The snapping sequence is as follows:
