How to Achieve High Reliability with 8-Layer PCBs?
Three Breakthroughs in High-Density Interconnect
Layered Signal Isolation
• Stackup Strategy: Layer 1/8 for 25Gbps high-speed differential pairs, Layer 3/6 for 10Gbps mid-speed signals, Layer 2/7 as ground planes, and Layer 4/5 for power/low-speed signals. High-speed signals are "sandwiched" between ground planes, reducing crosstalk to -65dB.
• Impedance Control: High-speed traces maintain 0.1mm spacing to ground planes, limiting impedance deviation to ±2% (50Ω±1Ω), outperforming 6-layer boards (±3%).
3D Via Network
• Hybrid Via Tech: 0.15mm laser microvias (adjacent layers) + 0.2mm blind vias (cross-layer) + 0.3mm buried vias (internal signals). Via density reaches 15/cm² (vs. 10/cm² in 6-layer boards).
• Via Optimization: Aspect ratio 1:3 (hole/pad), copper wall thickness uniformity

**Chamfered Edge vs. Conventional Edge Processing: How to Choose for PCB Mass Production?**

⚡ **Signal Integrity: The Decisive Factor in High-Frequency Scenarios**
1. **Return Loss Comparison**
• *Right-angled edge*: 70Ω impedance discontinuity, 1/3 of 10GHz signal reflected.
• *Rounded corner* (radius 0.1mm): Return loss -18dB, limited improvement.
• *Chamfered edge* (45° + 0.3mm): Impedance variation
