Abstract

This article describes a structure for optimizing the packaging of quartz crystal oscillators used in connection with integrated circuits and particularly for the packaging of "vertical pack" cystals which are less expensive than "flat pack" crystals. These vertical pack crystals are more readily breakable because of their traditional attachment to integrated circuits and circuit boards. The present structure permits vertical pack crystals to be used in a horizontal position; this configuration which is easier to assemble and to maintain and is less breakable than the structure involving a crystal in a vertical position.

Protective Insulative Mounting for Crystals

This article describes a structure for optimizing the packaging of quartz crystal oscillators used in connection with integrated circuits and particularly for the packaging of "vertical pack" cystals which are less expensive than "flat pack" crystals. These vertical pack crystals are more readily breakable because of their traditional attachment to integrated circuits and circuit boards. The present structure permits vertical pack crystals to be used in a horizontal position; this configuration which is easier to assemble and to maintain and is less breakable than the structure involving a crystal in a vertical position.

The mounting for the "horizontal pack" crystal structure is shown in the drawings, with Fig. 1 being a general isometric view, Fig. 2 being a top view, Fig. 3 being a sectional view along lines 3-3, and Fig. 4 being a side view. The crystal nest 10 is shaped to accept and support the crystal (not shown). As the crystal is inserted into the crystal nest, the pair of leads from the crystal, shown by dotted lines 11 and 12, are passed through a corresponding pair of holes 13 and 14 so that they can make appropriate connection to terminals in the supporting board 15. Crystal nest 10 is attached to supporting board 15 by any suitable means.
