Inspection

Swift Glass holds its commitment to fabricating products to the highest quality in the utmost regard.

Every order, regardless of whether it is one prototype, small quantities or a large volume production, passes through several extensive levels of quality control. These processes include first-piece inspection, random sampling and final checks just before shipment.

Glass Inspection

Tools which we employ to aid in these quality checks are:

  • Coordinate Measuring Machine (CMM)
  • Optical Comparator
  • Photoelastimeter
  • Polarimeter
  • Differential Surface Refractometer (DSR)
  • Grazing Angle Surface Polarimeter (GASP)
  • Surface Profilometer
  • High Powered Microscope
  • Interferometer
  • Optical Flat

To complement the functions of the above-mentioned inspection tools, the Swift Glass team recently added an ISO Class 7, (Class 10,000,) clean room and capabilities of ultrasonic bath cleaning and wafer measurement.

Wafer Measurement Capabilities

The addition of a Tropel® FlatMaster® MSP-300 frequency stepping interferometer to our state-of-the-art inspection facility allows us to provide precise wafer measurement capabilities, inclusive of wafer thickness and flatness across the wafer’s entire surface. By using this high-frequency tool, our technicians can collect more than three million submicron-level data points within a few seconds.

This new tool is a sought after addition to our already extensive list of advanced capabilities which include:

To support mission-critical applications across defense, aerospace, and medical fields, Swift Glass maintains a rigorous quality framework:

  • ISO 9001:2015 Certified: Standardized operational and manufacturing quality management systems.
  • ITAR Registered: Fully compliant with International Traffic in Arms Regulations to handle restricted military and government defense contracts.
  • Industry Compliant: Manufacturing processes aligned with ASME, ASTM, and stringent military specifications.

Our climate-controlled inspection lab is outfitted with an array of advanced metrology instruments:

  • Tropel® FlatMaster® MSP-300: A non-contact, frequency-stepping interferometer for sub-micron surface metrology.
  • Optical Comparators & Vision Systems: High-magnification CNC dimensional verification units.
  • Digital Micrometers and Calibrated Thickness Gauges: Handheld and automated contact instruments for linear dimensions.
  • Scratch-Dig Standards: Visual and optical comparison sets to verify surface cosmetic classifications.

The addition of the FlatMaster® MSP-300 provides unparalleled capabilities for precision glass wafer and optical flat inspection. This system collects over three million submicron-level data points across the entire surface of a 300 mm substrate within seconds. It delivers a comprehensive map of wafer thickness, total thickness variation (TTV), bowing, warp, and absolute flatness, eliminating human error and ensuring absolute compliance with semiconductor line standards.

Our structured quality control process is integrated directly into the production floor and contains three core gates:

  1. First-Piece Inspection: Verification of setup parameters and the initial part before full production proceeds.
  2. In-Process Random Sampling: Continual, statistically driven audits during execution to identify and eliminate machine drift.
  3. Final Check Inspection: Comprehensive dimensional and cosmetic screening of completed lots immediately prior to packaging and shipping.

Yes. We provide full material traceability and inspection reporting upon request, including First Article Inspection Reports (FAIR), Certificates of Conformance (CoC), and specialized regulatory reporting such as Conflict Minerals Reporting Templates (CMRT).
