Castellated Holes in PCB Design
Castellate holes, also known as plated half-holes, are structures resembling barriers along PCB edges. They are commonly used in signal circuits for onboard connections.
Benefits of Castellated Holes
- Enable modular board creation
- Allow flexible pin layout changes
- Facilitate easy mounting onto other PCBs
- Useful for wireless PCB-to-PCB links
Applications of Castellated Holes
Castellated holes are primarily used to produce PCB modules like Wi-Fi or Bluetooth components, aiding in PCB-to-PCB connections.
Manufacturing Process
- Determine hole dimensions
- Drill initial holes
- Expand holes with metallization
- Finalize hole dimensions
Functionalities of Castellated Holes
- Galvanic isolation for electrical interference prevention
- Component fixation and ventilation
- Grounding for circuit stability
Castellated holes are essential in PCB design, offering various functions to enhance circuit performance and reliability. They are commonly used in creating PCB modules like Bluetooth and Wi-Fi components, ensuring a robust wireless connection between circuit boards.
