You might get away with this strategy on a simple design with only a handful of parts. Do I really need to make a BOM? Can’t I just wing it and start ordering parts online based on the mental list in my head? Now, we know what you might be thinking at this point. If you’re working in any engineering domain that involves a product being physically built, then you’ll be using a BOM. But rather than just a general shopping list with a one-word value for an item, an item in a BOM contains a ton of information that makes it easy to identify, shop for, and purchase.ĭo you love spreadsheets? Then you’ll love making a Bill of Materials! (Image source)īOMs are used everywhere, not just for PCBs. It contains all of the ingredients (parts) that go into making your PCB design complete. You can think of it as a kind of shopping list for your electronic design. If this is your first time having a PCB manufactured then a BOM might sound a bit foreign.

To keep all of these parts and their information organized you’ll need to make yourself a Bill of Materials (BOM) in Autodesk EAGLE. You’ve likely got dozens of components that need to be ordered and assembled, and there are many places to buy them.

But where do you even start with the part assembly process? Components provide all of the functionality on a circuit board, powered by all of that copper you spend hours designing in EAGLE. Now it’s time for the second half of your manufacturing journey, assembling the parts on your PCB. This documentation is then handed off to your manufacturer to produce your bare board. In PCB Manufacturing Basics Part 1 we walked through the process of generating Gerber and NC Drill Files in Autodesk EAGLE. 11 min read PCB Manufacturing Basics Part 2: How to Create a Bill of Materials (BOM)
