This study case is about 8-Layer HDI PCB with edge connector.
KnownPCB always keep challenging at this kind of HDI PCB. During the manufacturing process of this HDI circuit board with edge connector, we strictly control over blind via formation, layer alignment and 45° edge plating to ensure stable contact performance and reliable interconnection for this 8-Layer HDI board in industrial high-density edge connector applications.
For this 8-layer HDI PCB with edge connector case, the required process parameters for PCB design are as follows:
1. HDI board structure: 8-layer
2. HDI structure type: 1+6+1
3. Blind Vias: Laser-drilled blind vias between L1–L2 and L5–L6
4. Edge Treatment: 45° beveled edge (Ensure smooth insertion, enhance contact stability, and avoid scratching connectors in industrial connector-based applications)
5. Board Thickness: 1.9 mm
6. Surface Finish: ENIG 5U" (Electroless Nickel Immersion Gold)
7. Dimensions: 215 mm × 182 mm
8. Material Model: FR4 TG170
