Semiconductor PCB FAQ
Insights into high-layer count manufacturing and precision testing hardware.
How do you maintain registration accuracy in 40+ layer boards?
We utilize state-of-the-art Mass Lam systems with X-ray drilling and LDI imaging. Our environmental controls are strictly maintained at ISO Class 5 clean-room standards for these layers to prevent any thermal expansion mismatch or dust contamination during the lamination cycle.
Can you handle ultra-thick copper for high-power burn-in boards?
Yes, we support heavy copper up to 10oz for power distribution layers. We also integrate copper coins and heat sinks directly into the PCB structure to manage the extreme thermal loads during high-stress chip testing.
What is your capability for high-speed signal integrity?
We offer advanced back-drilling to eliminate via stubs, and we work with a wide range of low DK/DF materials like Panasonic Megtron 7 and Isola Tachyon. We ensure signal propagation remains consistent across the entire test board interface for speeds up to 112Gbps.
Do you provide micro-section analysis for semiconductor-grade products?
Standard. Every semiconductor PCB order includes a detailed micro-section report, thermal stress coupon test results, and a complete ionic contamination analysis as part of our shipment documentation (CoC).
