In PCB design, you need to make sure that you are including your bill of materials to ensure that everything runs smoothly when the circuit board goes to production.
Of course, it is not always clear what to include in your BOM, so we have put together some tips for you. Keep reading if you would like to find out more about this.

Consider Why You Are Creating One
The first thing that you need to do when you are creating your BOM is to consider why you are actually doing this. This will help you to figure out what you need to include in your BOM and you can be sure that the right people are going to be able to use it.
Think about who is going to be using your BOM for reference and the risks that might be involved with this. You should ask if multiple products are going to be using the same sub-assemblies if you want to create an effective BOM.
If you are using PCB design software to create your design, then you should make sure to use the features that come with it to make your BOM.
Some companies include a Components Management Datasheet that will give you details on the components that you are using and can help you compare the different types. Use this effectively and you will be able to create a really useful BOM.
Choose How Many Levels You Need
When you are creating your BOM, you will need to think about how many levels it is going to need. There are two main types of BOM – single-level and multi-level. You should choose a single-level BOM if you need to give a broad overview of the product and those using the BOM only need to see one part of the design.
If your products can be changed quickly or you can only share certain parts of the BOM to people, then you should think about using a multi-level BOM.
Keep It Simple
Our final tip for those who are creating a bill of materials for a PCB is to keep it as simple as possible. In the structure, if you overcomplicate it, you might find that things don’t go to plan.
Make sure to only include the information that you are going to need in the BOM to make it work as effectively as possible. This should help you to create a good bill of materials.
If you are designing a PCB then you should make sure that you include a BOM to ensure that your manufacturer knows exactly what is going on.
Make sure to follow all of the advice that we have given you about what to include in the BOM and how to structure it properly.
Make sure to keep it simple and make use of any BOM or component features that your design software comes with to create a successful BOM.
