Abstract
An apparatus and method for removing a temporary substrate from an optical disk is disclosed. A holding fixture (102) provides an optical disk supporting surface. A force imparting tool (118) imparts a force against an optical disk wherein a reaction force to the force imparting tool is provided by the supporting surface. The optical disk is flexed to break away and remove a temporary substrate of the optical disk.
Claims10
An apparatus for removing a temporary substrate from an optical disk, comprising:
- a holding fixture which provides an optical disk supporting surface that includes suction cups for securing an optical disk;
- and
- a force-imparting tool, which imparts a force against a fixed contact region of an optical disk wherein, a reaction force to the force-imparting tool is provided by the supporting surface such that the optical disk is flexed to break away and remove a temporary substrate of the optical disk.
An apparatus for removing a temporary substrate from an optical disk preassembly, comprising:
- a holding fixture which provides an optical disk supporting surface that includes suction cups for securing an optical disk, the holding fixture including anvil portions which support diametrically opposing end portions on a same side of the optical disk preassembly, the anvil portions each including a pivot;
- and
- a force imparting tool which imparts a force against an optical disk preassembly such that the anvil portions rotate about their respective pivot to cause the optical disk preassembly to be flexed to break away and remove a temporary substrate of the optical disk.
An apparatus for removing a temporary substrate from an optical disk preassembly, comprising:
- a holding fixture which provides an optical disk supporting surface, the holding fixture including anvil portions which support diametrically opposing end portions on a same side of the optical disk preassembly, the anvil portions each including a pivot;
- and
- a force imparting tool, including a plate, which imparts a force against an optical disk preassembly such that the anvil portions rotate about their respective pivot to cause the optical disk preassembly to be flexed to break away and remove a temporary substrate of the optical disk.
An apparatus for removing a temporary substrate from an optical disk preassembly, comprising:
- a holding fixture which provides an optical disk supporting surface which includes recesses to alignment of an optical disk preassembly, the holding fixture including anvil portions which support diametrically opposing end portions on a same side of the optical disk preassembly, the anvil portions each including a pivot;
- and
- a force imparting tool which imparts a force against an optical disk preassembly such that the anvil portions rotate about their respective pivot to cause the optical disk preassembly to be flexed to break away and remove a temporary substrate of the optical disk.
A method for removing a temporary substrate from an optical disk preassembly, comprising the steps of:
- bonding two half discs with a bonding material to form an optical disk preassembly;
- placing the preassembly in a holding fixture;
- imparting a force to a side of the disk opposite from a temporary substrate which is to be removed to flex and break the temporary substrate without permanent damage to other portions of the preassembly;
- forming an optical disk from the preassembly without the temporary substrate.
