Quartz Layering
Grooved quartz rods and slotted quartz bars have repeated machined features along their length. Use the part drawing or an existing sample to identify the cross-section, groove geometry and mounting details. The finished profile should match the mating fixture and the parts it supports.
Round Rods and Rectangular Bars
A grooved round rod is defined by its diameter and the orientation of the grooves. For a slotted rectangular bar, provide width, thickness and the face on which the slots are cut. For both shapes, identify the unmachined end lengths and any mounting features.
Applications in Quartz Process Fixtures
Slotted quartz supports are used in some wafer carriers and process fixtures to position substrates at repeated intervals. If the part is for an existing quartz boat, include the boat drawing or a reference sample, the substrate size and how the support is mounted.
