Cutting-Edge 12 Layer PCB Manufacturer

Mastering High-Frequency & Extreme Density

A 12-layer PCB is not a standard board; it is a highly tuned electromagnetic environment. We provide the manufacturing precision required for 100G/400G optical transceivers, massive MIMO antennas, and AI-driven edge servers.

The Power of Hybrid Stackups (Mixed-Dielectric)

In high-frequency RF and microwave applications (like 5G mmWave), signal loss must be minimized. While materials like Rogers RO4350B or Panasonic Megtron 6 offer incredibly low Dissipation Factors (Df), building an entire 12-layer board out of them is prohibitively expensive.

Our Solution: We specialize in mixed-dielectric lamination. We can press ultra-low loss high-frequency laminates on the outer layers (L1-L2, L11-L12) where the critical RF signals reside, while using cost-effective High-Tg FR-4 (like Shengyi S1000-2) for the inner digital, power, and ground planes. This delivers peak RF performance at a fraction of the cost.

Advanced Microvia Technology (HDI)

Modern network processors and FPGAs are packaged in massive BGAs with pin pitches of 0.5mm, 0.4mm, or even tighter. Routing thousands of signals out of these chips on a 12-layer board is impossible with standard through-holes.

We utilize state-of-the-art Mitsubishi CO2 laser drills to create highly accurate microvias. Our capabilities include:

• Any-Layer HDI: Complex sequential lamination (3+N+3 or Any-Layer) allowing vias to connect any two adjacent layers.
• Stacked & Staggered Microvias: Copper-filled stacked vias for straight vertical routing, or staggered vias for improved mechanical reliability.
• Via-in-Pad (VIPPO): Essential for fine-pitch BGA fan-outs, filled with conductive or non-conductive epoxy and plated flat.

Extreme Routing Density & Backdrilling

When dealing with 12.5 Gbps or 28 Gbps SerDes channels, the unused portion of a plated through-hole (the "via stub") acts as an antenna, causing severe signal reflections and resonance. We employ precise Controlled Depth Backdrilling to remove these stubs from the 12-layer stackup, significantly clearing the eye diagram and improving overall Signal Integrity (SI).
