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.

Grounding Methods for Multi-Layer PCB Boards

Four-layer PCBs are typically used for high-density, high-frequency applications and offer more than 20 dB better electromagnetic compatibility (EMC) compared to two-layer boards. In a four-layer board setup, a complete ground plane and a full power plane can be used. This allows the various circuit ground wires to be connected to the ground plane effectively, with working noise managed separately.

Precautions for PCB Design

In PCB design, circuit layout is fundamental for engineers. However, even experienced engineers may overlook critical details in basic PCB design, which can lead to errors. Sometimes, these errors may cause problems or even a complete failure of the circuit when converted into a PCB. To help engineers avoid redesigns and improve work efficiency, here are some essential aspects to consider during PCB design.
