The Applied Technical Services Family of Companies (ATS FoC) offers reliable Total Thickness Variation (TTV) measurement services to help manufacturers maintain product quality and meet dimensional standards. TTV quantifies the difference between the thickest and thinnest points of a component, which is critical for products that require uniform thickness and flatness. Manufacturers rely on TTV inspections throughout product development, material verification, process validation, and final quality control, as even minor thickness variations can affect assembly, performance, and reliability. Our inspectors provide accurate data to support production decisions and help customers maintain confidence in their processes.
When Should Manufacturers Perform Total Thickness Variation Testing?
Manufacturers should conduct Total Thickness Variation (TTV) testing whenever thickness uniformity affects product performance, assembly precision, or compliance with engineering specifications. Design engineers request TTV measurements during product development to confirm that manufacturing processes meet required tolerances. Production teams use routine TTV inspections during manufacturing, material verification, process validation, and final quality assurance to identify dimensional variation before it impacts yield, reliability, or downstream operations. Industries such as semiconductor, precision machining, optics, ceramics, glass, and coatings regularly include TTV testing in quality control programs to ensure dimensional consistency and reliable performance.
Common applications include:
- Semiconductor wafers and electronic substrates
- Precision-machined metal and polymer components
- Optical glass and specialty ceramics
- Thin-film and coated materials
- Medical, aerospace, and advanced manufacturing components Our Total Thickness Variation Inspection Capabilities
