One critical item that can be cut down at this point of your design process, which a single check list item I don’t think really covers sufficiently is bill of material (BOM) line count reduction. You should be able to take this list and customise it to your requirements in a fraction of the time of coming up with every item yourself, as I know you probably just don’t have enough hours in your schedule to come up with the perfect design checklist for your specific use case without some form of seed list. The goal is to provide you with 90% of the checklist that you need to improve your design review process.

Likewise, there are likely many items that are not going to be applicable to a basic device. While I’ve attempted to make it as comprehensive as possible, there are still going to be many items that are relevant to specific projects that focus heavily on RF, high speed, or very small signal processing which you will want to add. Instead, this article is a simple no frills schematic review checklist. There are many articles on this blog from myself and other industry experts which cover the reasons and importance of the items presented here. If they are relevant to your product, you should probably already know what they mean - if not, you should probably look them up. I’m also not going to go into great detail on the items on this schematic review checklist. In this article, I’m not going to extol the virtues of a good schematic design, as I’ve already done that in my article about creating elegant, readable schematics. Often these schematic reviews still let many issues pass through which are not found until the prototype is tested, as all too many companies are too pressed for time to come up with a formal design review checklist relevant to their products. In many companies, design reviews are performed to approve a schematic design to proceed for layout - whether the schematic engineer is the layout engineer or not. Mistakes in your schematic design can easily make their way all the way into prototypes or production without a second thought once layout starts. One of the most common points of failure of a device, especially when prototyping occurs even before you start to layout your circuit board.
