Guide to Restoring Circuit Diagrams from Physical PCBs

Often, products come without a circuit schematic, making it challenging to understand the PCB’s functionality and design principles. When faced with such a situation, follow these steps to reverse-engineer and restore the circuit diagram. This guide provides detailed instructions for accurately translating a physical PCB back into a schematic diagram.

Overview of DFM Technical Requirements for PCB Process

Design for Manufacturability (DFM) optimizes designs for the manufacturing process, making it an essential component of concurrent engineering. By considering factors such as manufacturability and assembly requirements early in the design phase, DFM streamlines production, bridges CAD-CAM communication, and enhances product reliability. Here, we cover general technical requirements for DFM in PCB manufacturing.

Practical Experience in PCB ESD Design

Recently, I have been conducting ESD (Electro-Static Discharge) testing on various electronic products. From the test results, I realized that ESD is crucial: if the PCB design lacks proper ESD protection, static electricity can cause devices to freeze or even damage their components. Previously, I only understood that ESD could damage individual components, but now I see the importance of giving full attention to ESD protection throughout the entire design process.
