FAQ
Q1: What's the minimum order quantity for custom shims?
A: 100 pieces for standard designs (1-2 pieces for prototyping).
Q2: How do your etched shims compare to stamped shims?
A: Our etching process provides:
Better flatness (no stamping distortion)
Tighter tolerances (±0.003mm vs ±0.05mm)
No burrs (eliminates secondary processing)
More complex geometries
Q3: Can you produce shims with multiple thicknesses in one piece?
A: Yes! We specialize in stepped shims with precision thickness transitions.
Q4: What certifications do your medical-grade shims have?
A: Our cleanroom-produced shims meet:
ISO 13485
FDA 21 CFR 820
EU MDR 2017/745
Q5: How should shims be stored before use?
A: We recommend:
Anti-tarnish paper interleaving
20-25°C, 40-60% RH environment
Use within 12 months for critical applications
Q6: Do you offer conductive/non-conductive coatings?
A: Yes, including:
Gold plating (high conductivity)
Anodizing (insulation)
DLC coating (wear resistance)
