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)
