Castellation PCB By Feature

Half-Hole Castellation PCB

The Half-Hole Castellation PCB requires its hole to be plated. As its name indicates, this type of hole is cut in half throughout the board. Additionally, they are the best alternative for combining two different circuit boards.

Multilayer Castellation PCB

The Multilayer Castellation PCB offers more flexibility in some situations. However, the more layers you add, the more it will reduce its versatility. They are highly preferred in high-end consumer electronics applications.

HDI Cut Castellation PCB

The HDI Cut Castellation PCB has become more popular in the communications industry because of its high signal integrity since it utilizes blind via and via in-pad technology. Also, it is a relatively inexpensive type of board.

Customized Hole Castellation PCB

The Customized Hole Castellation PCB is ideal in applications wherein it requires a lot of freedom in designing the layout, and integrating several components. We are capable of providing this for you.

Edge Plating Castellation PCB

The Edge Plating Castellation PCB can also be termed copper plating. It covers the surfaces of the circuit board from top to bottom. In addition, this type of board is ideal if you’re seeking a reliable connection between the board and traces.

Blind Via Castellation PCB

The Blind Via Castellation PCB is a way of connecting layers. A blind via connects only two or more inner layers. In addition, it penetrates from the outer layer of the board, but it will not pass through to the next outer layer.

Castellation PCB By Layer (5)

  • 4-Layer Castellation PCB

    The 4-Layer Castellation PCB has way better thermal control than the lower count layered boards. Also, the more layers it has, the more durable it will be. Thus, it is suitable for industrial control applications.

  • 6-Layer Castellation PCB

    The 6-Layer Castellation PCB offers way better routing for low to high-speed signals compared with the 4-Layer. In addition, it possesses enhanced EMI. As a result, they are becoming popular in the communications industry.

  • 8-Layer Castellation PCB

    The 8-Layer Castellation PCB is highly preferred in complex devices wherein there’s a need for reduced EMI. It can be a cost-effective option due to its longer lifespan and increased overall performance.

  • 12-Layer Castellation PCB

    The 12-Layer Castellation PCB is suitable for high-speed electronic devices because of its two additional signal layers that improve the overall signal integrity. They are economical because it is halogen-free and lead-free.

  • 16-Layer Castellation PCB

    The 16-Layer Castellation PCB has become more popular in high-density and high-frequency applications because of its capability to reduce signal interference. Thus, they are ideal in the communications industry.

Castellation PCB By Surface Finish (5)

  • ENIG Castellation PCB

    The ENIG Castellation PCB is the most recommended surface finish in the industry because of its wide array of benefits including its average cost, longer shelf-life, and exceptional flatness and smoothness it offers to the board.

  • Immersion Silver Castellation PCB

    The Immersion Silver Castellation PCB requires thorough and sealed packaging because of its risk of tarnishing when exposed to air. However, it has the capability to be reworked.

  • OSP Castellation PCB

    The OSP Castellation PCB can also be termed as the ant-tarnishing finish due to its organic materials that prevent the copper from being oxide. In addition, they are considered to be ecologically friendly since it doesn’t have any lead.

  • HASL Castellation PCB

    The HASL Castellation PCB is the least expensive type of finish among all the others. They offer a good balance between through-hole and large SMT components. In addition, this type of finish can be free from lead too which makes it economical.

  • Immersion Tin Castellation PCB

    The Immersion Tin Castellation PCB is ideal for small components due to the flatness of its coating. In addition, this finish offers a smooth and flat surface. It can be very sensitive to touch; thus, gloves must be worn.

  • Next, plating through the hole is performed.
  • Panel plating, milling castellation holes, and removing anti-plate films.
  • It now undergoes PCB Etching to remove the unwanted copper.
  • Next, peel tin from the substrate and remove it from the holes.
  • Finally, we expose the copper of the Castellation holes.

Each of these phases in the production procedure has its own guidelines for performing; we only deploy the most experienced staff to conduct these.

Castellation PCB: The Ultimate FAQ Guide

If you are considering purchasing a new PCB, you may be wondering if the Castellation PCB has a solder resist layer. If you are still unsure, read our FAQ about Castellation PCBs. It will address many of your most common questions about the process, from choosing a board to ordering components. Read on to learn how these features work and how they can help you improve your design.

What is a Castellation PCB? It’s also called edge plating PCB. The vias are placed on the outer edges of the Castellation PCB. These holes are semicircles that help with board assembly. When soldering, these holes allow you to align the boards and ensure they are positioned correctly. Here are some frequently asked questions about Castellation PCBs, including how they differ from other types of boards.

What exactly is a Castellation? This method connects two PCBs directly and is ideal for small modules and breakout boards. It also supports wireless PCB-to-PCB connections. Soldering modules with perforations can be difficult, so make sure you understand how to properly connect the two boards. Castellation PCBs should have as many holes as possible to fit the space you are using.

How do I make Castellation holes in the PCB? Unlike traditional holes, these specialized holes are drilled from the edge of the substrate and allow you to place SMD components. Although it is difficult to create such holes during standard PCB manufacturing, they are an important part of many electronic devices. This article will describe how to create and use Castellation PCBs.
