FAQ

Semiconductor PCB FAQ

Common questions about IC test board manufacturing, impedance control and ATE standards.

Ask a Specialist
01
What is the maximum layer count you can manufacture for ATE boards?

We leverage industry-leading fabrication technology to produce boards with 50+ layers. This capability is essential for complex semiconductor load boards and probe cards that require massive parallel routing and dedicated power planes.

02
How precise is your impedance control for high-speed test paths?

We provide standard impedance control at ±5%. For ultra-critical high-frequency paths in ATE and high-speed IC evaluation, we can achieve precision tolerances as tight as ±2% using verified material stack-ups and advanced TDR testing.

03
Do you support back-drilling to eliminate signal stubs?

Yes. We use precision laser and mechanical back-drilling to remove redundant plating stubs. This is a critical requirement for ATE load boards to ensure clean signals and minimize reflection at frequencies above 10GHz.

04
How do you handle high-power IC heat dissipation during test?

For high-power AI and server chips, we design boards with heavy copper layers (up to 12oz) and metal core inserts or copper-coin technology to manage the extreme thermal loads produced during long-duration burn-in cycles.
