Think about an Arduino hat or shield board form factor instead of using pin headers to mate two boards, you can design the main board with castellated pads to mount an array of castellated holes. Castellated Edges in Your ECAD SoftwareĬastellated holes are used on small modules as an alternative to pin-header mounting. You’ll have to approach this while thinking about the fabrication process and some difficulties in assembly, but the basic objects in your ECAD tools can be used to easily place castellated holes on your PCB. These small modules are becoming more popular and are simple to work with, but they might look a bit specialized for use in the standard PCB fabrication process.Īlthough modules with castellated holes and add-on holes for pin headers might not seem to fit into the standard list of design objects in your CAD software, there is a simple strategy for placing an array of castellated holes on a module. If you look at these modules, it should be evident how castellated holes PCBs can be used to mount a PCB module as an SMD component. This connector cannot be created automatically using the IPC Compliant Footprint Wizard, so it must be created manually using the recommended PCB layout view from the datasheet.SMD modules like the ESP32-WROOM or Raspberry Pi Pico microcontroller board use a particular mounting style called castellation PCB. If you have closed the tab with this component, search for it in the Components panel, right-click on its name then select Edit. Let’s create a footprint for the GSB343K33HR component whose symbol was created in chapter 5.1. In Altium Designer, the process of creating footprints is simple, convenient and protected from errors as much as possible. Any error in the placement of the footprint pads can lead to problems, up to and including the inability to assemble the final device, so library designers should be very careful while creating footprints.

Also, the component itself will be soldered onto these contact points, so their configuration should be fully consistent with the actual metal objects of the component. Component footprints contain a set of graphical primitives and copper pads or holes that will be connected to the conductors and will provide a connection. The next step in creating the component is to design the footprint.
