What is the cost of manufacturing multilayer PCB?

Multidimensional Analysis of PCB Cost Structure

As the core carrier of electronic systems, the manufacturing cost of PCBs is influenced by a variety of factors, including materials, processes, design complexity, and quantity. According to the IPC-6012 standard, the cost structure of modern PCBs can be broken down into the following key dimensions:

The specific price is subject to actual communication.

1. Substrate Cost (25-40% of total cost):

• Standard FR-4 epoxy glass cloth substrate: ¥50-150/m²
• High-frequency materials (e.g., Rogers RO4003C): ¥800-2000/m²
• High TG materials (TG170+): 30-50% higher than standard FR-4
• Aluminum substrate (IMS): ¥300-800/m²

2. Copper Foil Cost (15-25% of total cost):

• Standard 1oz (35μm) electrolytic copper foil: Base price
• 2oz copper foil: 35-40% cost increase
• 3oz+ thick copper: Exponential cost growth

3. Process Cost (30-45% of total cost):

• Standard through-hole board process: Baseline cost
• Blind/buried via process: 20-30% cost increase
• HDI (High Density Interconnect) process: 50-100% cost increase
• Impedance control requirements: 15-25% additional cost

Quantitative Analysis of Layer Count Impact on Cost

The relationship between PCB layers and cost shows nonlinear growth, determined by the following engineering factors:

Notably, 4-6 layer boards offer the best cost-performance ratio in consumer electronics, with cost increases primarily from:

• Additional lamination steps (each lamination costs ¥15-25/m²)
• Reduced inner layer pattern transfer yield (typically 85-90% vs outer layer 95%+)
• Higher drilling accuracy requirements (hole position accuracy must be within ±25μm)

Cost Premium Analysis of Advanced Processes

Modern electronics demand high performance and reliability from PCBs, with associated special processes impacting costs as follows:

1. HDI-Technik (High Density Interconnect):

• Laser drilling (¥0.002-0.005/hole) vs mechanical drilling (¥0.0005-0.001/hole)
• Any-layer interconnect structures increase costs by 80-120%

2. High-Frequency Material Processing:

• PTFE materials require special drilling parameters, reducing processing efficiency by 30%
• Surface treatment requires ENIG (Electroless Nickel Immersion Gold), 60% more expensive than HASL

3. High-Reliability Requirements:

• IPC Class 3 standards increase costs by 20-30%
• 100% electrical test coverage adds 8-12% cost
• Aerospace-grade cleaning processes add 15-20% treatment cost

Engineering Practices for Cost Optimization

Based on Design for Six Sigma (DFSS) principles, we propose the following cost optimization strategies:

1. Design Phase Optimization:

• Rational layer count selection (verified through simulation)
• Optimized routing rules (reducing special impedance line ratio)
• Standardized aperture sizes (reducing drill bit change frequency)

2. Material Selection Strategy:

• Hybrid material design (critical layers using high-performance materials)
• Copper thickness optimization (precisely calculated based on current load)
• Surface treatment selection (consumer electronics can use OSP instead of ENIG)

3. Manufacturing Process Control:

• Implement Statistical Process Control (SPC) to improve yield
• Apply Overall Equipment Effectiveness (OEE) management
• Establish Supplier Quality Engineer (SQE) systems
