VC America Electronics Scale Manufacturing
VC America Electronics Scale Manufacturing
Our high-quality scales increase yield and performance with better patterning and fewer, smaller defects.
Ultra-precision patterning with nanometer photolithography improves repeatability and cycle-to-cycle accuracy for exceptional optical performance.
Pitches down to 2µm are possible.
Reflective and Anti-Reflective (AR) coatings and track patterns are optimized for each requirement.
Typically 850nm (Near Infra-Red), 650nm (Red LED), or 450nm (Blue).
Substrate materials include:
- Soda-lime glass for precision scales
- Stainless Steel (0.1-0.4mm thick) for ultrathin scales
- Low CTE Glass compositions for ultimate accuracy.
We collaborate with you to design and produce scales that match your encoder and your physical, environmental, and accuracy requirements.
