## Introduction

 

As FPGA devices push into ever-higher performance tiers, the PCB that carries them becomes a critical success factor. Xilinx Kintex-7 (XC7K410T) and Virtex-7 (XC7V690T) FPGAs demand nothing less than precision-engineered, high-layer-count PCBs with meticulous attention to signal integrity, thermal management, and manufacturing tolerances.

 

At **Superb Automation Co., Limited**, we specialize in the PCB fabrication and assembly of FPGA carrier boards — from initial prototyping through volume production, backed by our **lifetime warranty**.

## What Makes FPGA Carrier Boards Different

 

A typical Kintex-7 or Virtex-7 carrier board is not a standard PCB. It represents the intersection of multiple high-complexity design requirements:

 

### 1. High Layer Count (12–18 Layers)

 

The BGA packages on XC7K410T (676/900-ball FFG) and XC7V690T (1761-ball FFG) require extensive layer stacking to achieve proper breakout:

 

 

| FPGA          | BGA Package     | Typical Layer Count |

| ------------- | --------------- | ------------------- |

| Kintex-7 410T | FFG676 / FFG900 | 12–14 layers       |

| Virtex-7 690T | FFG1761         | 16–18 layers       |

 

Each additional layer pair adds routing channels for the high-density interconnects between the FPGA, DDR memory, high-speed transceivers, and peripheral interfaces.

 

### 2. BGA Fanout & Microvia Technology

 

1761-ball BGA packages demand sophisticated fanout strategies:

 

- **Dog-bone fanout** for outer rows

- **Via-in-pad with microvias** for inner rows

- **Stacked or staggered microvias** for layer transitions

- **Laser-drilled blind vias** (100–150μm)

 

Superb's PCB partners are equipped with **direct imaging LDI**, **laser drilling**, and **plasma desmear** processes to achieve reliable microvia structures with aspect ratios up to 1:1.

 

### 3. Controlled Impedance (50Ω / 100Ω Differential)

 

FPGA carrier boards carry multiple high-speed interfaces, each with specific impedance targets:

 

 

| Interface            | Impedance              | Data Rate                             |

| -------------------- | ---------------------- | ------------------------------------- |

| GTX/GTH Transceivers | 100Ω differential     | Up to 12.5 Gbps (K7) / 13.1 Gbps (V7) |

| DDR3/DDR4 Memory     | 50Ω single-ended      | Up to 1866 Mbps                       |

| PCIe Gen2/Gen3       | 85–100Ω differential | 5–8 Gbps per lane                    |

| SFP+/QSFP+           | 100Ω differential     | 10–28 Gbps                           |

 

We validate every impedance-controlled trace with **TDR testing** and provide full impedance coupons with each panel.

 

### 4. High-Speed Material Selection

 

Standard FR-4 is insufficient for multi-gigabit FPGA designs. We recommend and stock:

 

 

| Material            | Dk @ 10GHz | Df @ 10GHz | Best For                  |

| ------------------- | ---------- | ---------- | ------------------------- |

| Rogers RO4350B      | 3.48       | 0.0037     | GTX transceiver routing   |

| Isola I-Speed       | 3.64       | 0.0060     | Mixed-signal layers       |

| Panasonic Megtron 6 | 3.60       | 0.0020     | Ultra low-loss backplanes |

| Shengyi S1000-2     | 3.50       | 0.0045     | Cost-optimized high-speed |

 

### 5. Backdrilling for High-Speed Vias

 

At data rates above 5 Gbps, via stubs become significant signal integrity problems. We offer **controlled-depth backdrilling** to remove unused via barrels on GTX/GTH signal layers, reducing stub resonance and improving eye diagram opening.

 

### 6. Thermal Management

 

XC7V690T can dissipate 20–30W under full load. Our PCB designs incorporate:

 

- **Thermal via arrays** under the FPGA BGA (0.3mm drill, 0.8mm pitch)

- **Copper coin / embedded copper** options for extreme thermal cases

- **Heavy copper layers** (2oz–6oz) for power distribution
