Compatibility Between the Product Geometry and Process Route
The review separates the intended operation from product-family assumptions and drawing-specific constraints.
| Review area | Assigned technical basis |
|---|---|
| Process purpose | Cutout / Window Machining: source-backed external reference facts retained from V3.2.1; only numeric facts are counted as numeric capability data. |
| Product geometry | Round wafer, flat/notched wafer, carrier wafer, structured wafer or bonded panel coupon |
| Typical input form | Flat sheet, blank, tube, rod or preform as applicable to the named process |
| Process limitations | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Inspection basis | Dimensional and visual inspection; add microscopy, profilometry or interferometry when the drawing requires it |
Glass Wafer Features That Affect the Process
Product-form records describe typical geometry and inspection needs; the supplied glass grade and drawing remain controlling inputs.
| Product requirement | What to define |
|---|---|
| Geometry and available forms | Round wafer, flat/notched wafer, carrier wafer, structured wafer or bonded panel coupon |
| Dimensions and thickness | 4–12 inch semiconductor quartzware context; wafer diameter and SEMI edge/notch requirements must be specified |
| Holes, cutouts and features | Dimension holes, slots, cutouts, steps, grooves, radii and their edge distances. |
| Edge and surface zones | Ground edge, chamfer or SEMI-style profile selected to reduce handling fracture |
| Inspection | Thickness map, TTV/bow/warp metrology, interferometry, edge-profile inspection, particle and surface-defect inspection |
| Packaging and handling | State cleanliness, protective film, separators, individual packing and shipping requirements. |
Glass Cutout Machining References and Design Limits
Numeric values appear only when verified public process evidence is assigned. Proxy-family pages intentionally suppress numeric ranges.
| Process parameter | Reference value | Applicable condition |
|---|---|---|
| Minimum Thickness | 0.76 mm | JNS/Abrisa CNC fabrication program |
| Maximum Thickness | >25.4 mm | JNS/Abrisa CNC fabrication program; upper limit stated as greater than 25.4 mm |
| Minimum Part Size | 50.8 x 50.8 mm | CNC program; workholding may require larger size for individual features |
| Maximum Part Size | 2286 x 1524 mm | CNC program envelope |
| Dimensional Tolerance | ±0.508 mm general; up to ±0.127 mm | Provider CNC program; feature, material and size dependent |
| Design item | What must be reviewed |
|---|---|
| Thickness and part envelope | 0.76 mm >25.4 mm 50.8 x 50.8 mm 2286 x 1524 mm |
| Tooling and process condition | Valley uses 4- and 5-axis CNC machining for complex precision components. |
| Tolerance and finish | ±0.508 mm general; up to ±0.127 mm Abrisa states that custom CNC glass shapes can receive ground or polished edging. |
| Drawing review | For Glass Cutout Machining on Glass Wafer, identify the glass grade, datums, processed features, edge and surface zones, quantity and inspection method. |
Inspection Focus for Glass Wafer Cutout Machining
Inspect the processed feature together with adjacent edges, surfaces, wall sections and functional zones.
| Review item | Project-specific focus |
|---|---|
| Process defects | Chipping, cracking, subsurface damage, dimensional error, contamination or surface defects as applicable |
| Process limitation | Public supplier values are not universal; blank numeric fields indicate that no transferable public value was verified |
| Design condition | Define material grade, thickness, geometry, edge distances, datum scheme, surface/edge acceptance and inspection method |
| Product design risk | Edge chips, high TTV, bow/warp, particles, alkali contamination and mismatch with bonding temperature |
| Product inspection | Thickness map, TTV/bow/warp metrology, interferometry, edge-profile inspection, particle and surface-defect inspection |
| Acceptance method | Flatness Measurement: Compare calibrated result with the drawing, purchase order or approved test specification |
