When hardware projects move beyond simple designs into the world of AI processors, 5G modules, and XR headsets, a basic board won't suffice. You need a high-speed engine that manages signal integrity as much as it saves space. This is where our 10-layer FR-4 PCB steps in—a powerhouse built for the industry’s most demanding tech.


Engineering Precision

What makes this board elite is the Advanced Manufacturing logic. We utilize 4-Step Microvias, involving three laser drills and two press cycles to allow for any-layer connectivity. This drastically shortens signal paths, which is essential for 400G network switches.


Key features include:

· Via Tech: 50-80μm laser holes with a 1:0.8 aspect ratio for ultra-fine routing.

· Zero Lag: Delay Matching keeps signal skew under 5ps in differential pairs.

· 3D Validation: Every layout is optimized using Ansys HFSS simulation.


Built for Reliability

With a 1.4mm thickness and a sleek black oil finish, this board is as rugged as it is smart. The Immersion Gold treatment ensures perfect solderability for dense components in ADAS sensor arrays or 8K encoders.
