Everything PCB !

Without a doubt, castellated holes come with their advantages worth noting. They are the new thing, especially in the world of PCBs. The following are some of the merits of using castellated holes:

Easily change the pin layout of components

Castellated holes are advantageous when it comes to changing the pin layout. These holes give designers an easy time when they want to change the pin layout. Sometimes, users may have different pin layout requirements. With castellated holes, it’s relatively easy to change the pin layout.

Verify solder joint quality

Designers use castellated holes to combine two boards. When it comes to solder joint quality, castellated holes play an important role here. They are helpful as they help in validating the quality of the solder joint.

For small modules such as patch panels or Wi-Fi modules

Castellated holes are also helpful, especially for breakout boards and small modules such as Wi-Fi modules.

Create wireless PCB-to-PCB link

If there’s anything good about castellated holes, then it’s the fact that they foster wireless PCB-to-PCB links. Wireless links increase efficiency, flexibility, and bring about cost savings.

Further use in another component

Castellated holes are also advantageous as designers can use them in another component. PCBs that have castellated holes can easily mount to another PCB during production. The ease of mounting is another significant advantage that comes with castellated holes.

Easy installation

The ease of installation is an excellent reason to use castellated holes. Installing such holes on a PCB isn’t a complicated process as such. Unlike other types of holes, it’s easy to install castellated fixes.

Why to use castellated holes?

We use castellated holes for a whole lot of different reasons. Mostly, designers use them to create printed circuit board modules. Examples of these PCB modules include Bluetooth and Wi-Fi modules. We also use castellated holes in combining two boards. Castellated holes bring about excellent wireless PCB-to-PCB links.

How are castellated holes formed?

Creating or instead of forming castellated holes is not a complicated process as such. It’s a straightforward process than you may imagine. The creation of these holes is through a normal via the method. It includes drilling and copper plating full holes in the PCB, which involves cutting the top spot in half. These will form partial or half holes on the edge of the PCB.
