- Testing & Quality Assurance: Electrical testing, signal verification, and functional testing to ensure accuracy.
7. Cost of Measurement Device PCBs
Pricing for measurement device PCBs depends on size, layer count, materials, and production volume:
- Single-layer PCBs: Around $0.50 – $2 per piece.
- Multi-layer PCBs (4–8 layers): $5 – $20 per piece depending on complexity.
- Flexible PCBs: Typically $10 – $50 per piece, depending on thickness and bendability.
- High-frequency or specialized PCBs: Can range from $20 – $100+ per piece.
Factors such as copper thickness, surface finish (HASL, ENIG, immersion silver), and testing requirements also affect the overall cost. For bulk orders, manufacturers often provide significant discounts.
