It covers the process of reviewing the schematic from the overview page to the block diagram, the importance of third-party reviews, the verification of presented information, and detailed analysis of the block diagram. The lesson explains conducting thorough checks of component footprints and naming conventions, using the annotation tool and footprint manager. Moreover, it offers insight into the review of individual schematic pages, the importance of netlabels and components placing, and how to investigate connections carrying through multiple pages. Lastly, there is in-depth information about utilizing the Electrical Rule Checker (E-R-C), the role it plays in the project, and how to analyze the warnings and errors it presents.

In designing a product for the industry, including appropriate testing points has its own importance. These testing points allow for the validation and quality control of your board during and after manufacturing. While the video lessons have focused on the core aspects of PCB design, I recommend that you consider incorporating testing points into your board layouts. These points serve as access points for various tests, such as functional testing, debugging, and quality assurance checks. Including testing points not only ensures the reliability and performance of your final product but also simplifies the troubleshooting process during production or in the field. So, as you proceed with your PCB designs, keep in mind the importance of testing points, and consider adding them to your layouts especially when designing boards for production purposes. It's a valuable practice that can save you time and effort in the long run. If you are new to testing methods, here are some of the methods related to the fabrication, and basic functionality in the assembly of PCBs: Continuity Testing: This test is essential during assembly to ensure that there are no open circuits (breaks) and no short circuits (unexpected connections) on the PCB. It helps verify the basic electrical connectivity of the board. Functional Testing: Functional testing is crucial for verifying the basic functionality of the PCB after assembly. It ensures that the assembled board performs its intended functions correctly. In-Circuit Testing (ICT): ICT is performed during assembly to test individual components, connections, and basic functionality while the PCB is in operation. It helps identify faulty components or soldering issues that affect basic functionality. Flying Probe Testing: Although often used for prototypes and low-volume production, flying probe testing can verify basic connectivity and functionality after assembly without the need for custom fixtures. These testing methods primarily focus on verifying the basic functionality and integrity of the PCB during the assembly and fabrication stages. They help identify common issues related to manufacturing, component placement, soldering, and connectivity.
