Backplane PCB By Feature

High Speed Backplane PCB

In the intended device, the High Speed Backplane PCB is configured to pick up multiple connections.

HDI Backplane PCB

The HDI Backplane PCB meets the ever-increasing demand for data transmission. The goal is to avoid power/voltage distortion.

large backplane pcb

A Large Backplane PCB is one that is longer than 20 inches. We do design this specifically to your specifications.

Impedance Control Backplane PCB

Impedance Control Backplane PCB is an HDI-specific material. It features extensive capability for IT structures.

High Power Backplane PCB

When you require a High Power Backplane PCB, we strive for power integrity by employing materials such as the Taconic or Rogers PCB series.

Multilayer Backplane PCB

One of the primary benefits of a good Multilayer PCB is its adaptability to the most difficult applications, such as RF and mmWave utilization.

Backplane PCB By Layer (5)

  • 10 Layer Backplane PCB

    The 10 Layer PCB is highly adaptable to the equipment it must accommodate. It is mostly constructed of FR4 material and can withstand high voltage.

  • 16 Layer Backplane PCB

    Because of the daily telecom device use, high layer counts, including 16 Layer PCB, are becoming increasingly important and in great supply.

  • 20 Layer Backplane PCB

    The 20 Layer PCBs are frequently used for high-frequency. Some are aerospace PCBs utilized in aerospace computers. When applicable, we use SMD assembly.

  • 24 Layer Backplane PCB

    Because 24 Layer Backplane PCB is in high demand, it is not in danger of being phased out or running out of supply. Often, it’s the highest layer count for backplanes.

Backplane PCB – The Ultimate FAQ Guide

There are a few things you should know before you start designing your backplane PCB. This design is difficult because it involves managing thousands of connections and powering the daughter card. The backplane PCB requires 100 A of current, which can be difficult to handle. Therefore, pin alignment is the first step in designing a backplane.

A backplane PCB has many advantages over a standard PCB. For beginners, it can be made from a variety of materials, allowing you to choose the best one for your project. Secondly, it will help you to choose the right connector. Choose high-quality connectors as they affect signal integrity. Finally, consider the size of the backplane. If your backplane is too large, the signal will be lost.

Third, consider the price. The cost of multiple vias can be expensive, depending on the size of the vias and their diameter. Large terabit systems usually require thick backplanes. Likewise, placing multiple vias around the PCB creates a “fence” effect, refracting noise back to the source. This is not always the case, so it is worth comparing prices and specifications to find the best fit for your application.
