Custom 8 Layer PCB for Complex Multilayer Designs

Huayihai manufactures custom 8 layer PCBs for designs that outgrow four and six layers: dense BGA fanout, split power planes, and controlled-impedance signal routing. Boards are produced according to customer Gerber files and stack-up requirements.

At eight layers, stack-up execution becomes increasingly important for signal integrity, power distribution, and impedance consistency. Our process holds 3/3 mil trace and spacing, impedance control to ±5%, and copper up to 6 oz, verified to IPC-A-600 and 100% electrical testing before shipment.

Custom Manufacturing Only

We provide 8 layer PCB manufacturing according to customer Gerber files and technical specifications. We do not supply ready-made or standard products.

Product Specifications

Key Features

• Dedicated 8 layer fabrication within a 2–64 layer capability

• 3/3 mil trace and spacing on both prototypes and volume runs

• Controlled impedance to ±5% tolerance

• HDI options up to 2+n+2 with 3 mil laser microvias

• Heavy copper option up to 6 oz

• 100% electrical testing on every board

Manufacturing Highlights

An 8 layer board lives or dies by stack-up execution: lamination registration, layer-to-layer alignment, and impedance consistency across the panel. These are verified in-process, not just at final inspection.

Key service elements include:

• Stack-up and impedance review during engineering stage

• Controlled lamination and registration

• 3/3 mil line etch capability

• Impedance verification to ±5%

• 100% electrical testing before shipment

Typical Applications

8 layer boards commonly serve designs with dense routing and dedicated planes:

• Industrial Control Systems

• Communication Equipment

• Automotive Electronics

• Medical Devices

• Power Conversion and Drives

• Other 8 Layer PCB Projects
