![]() ![]() ![]() PCBs with castellated holes can be mounted easily to another PCB during final production. ![]() Integrated modules can be produced on a single PCB board using castellation, which can be used further into another assembly during production.These holes give ease to change the Pin layout of the component as per the user requirement.Castellated PCBs can be used as breakout boards for a particular portion of the larger PCB.These small sub-circuits can be mass-produced, tested and can be soldered on to the main PCB that contains other parts of the circuit whenever required. For example, if there is a circuit that includes an inverter, filter, or feedback loops. Castellations serve as a link between the module and the board onto which the module has to be soldered.īy creating these holes on the board edges, they can be used to replicate certain parts of a PCB circuit. Apart from these, board-to-board soldering is used, when there is a need to mount a board on the top of another PCB. Through Hole Technology (THT) and Surface Mount Technology are commonly used during PCB assembly process. Castellated holes are created on various PCB modules (Bluetooth or Wi-Fi modules), these modules can then be used as independent parts to be mounted onto another board during the assembly process. This mounting process takes place with the help of castellated holes and called board-to-board soldering. Such holes are designed to provide proper alignment between the boards while soldering. Depending upon the application, instead of half holes, they may also look like a small or larger portion of a broken circle. These Castellations help to mount one PCB board on top of another during assembly. Castellated Holes or Castellations are indentations created in the form of semi-plated holes on the edges of the PCB boards. ![]()
