PCB Manufacturing Process Overview
Printed Circuit Board (PCB) Manufacturing Steps
- 1. Design: The first step in PCB manufacturing is designing the layout of the circuit board.
- 2. Material Selection: Choosing the right materials is crucial for the performance of the PCB.
- 3. Etching: Etching is the process of removing unwanted copper from the board.
- 4. Drilling: Holes are drilled into the board to allow for component placement.
- 5. Solder Mask Application: A solder mask is applied to protect the board and provide insulation.
- 6. Silkscreen Printing: Component labels and indicators are printed on the board.
- 7. Testing: The final step is testing the PCB to ensure it functions correctly.

The Significance of Copper Coating in PCB Design
Purpose and Importance of Copper Coating:
- Enhancing ground wire impedance.
- Improving anti-interference capabilities.
- Minimizing voltage drop for better power supply efficiency.
- Reducing loop area to enhance soldering performance.
Implementation Strategies:
- Utilize intelligent copper coating functions in PCB design software.
- Fill open areas with copper or grid-like ground wires to prevent distortion during soldering.
Handling Grounds and Multiple Deformable Structures:
- Distinguish grounds like SGND, AGND, GND, and use the most critical ground as a reference.
- Separate digital and analog grounds for distinct copper pouring.
- Thicken power connections before copper pouring for optimal structural integrity.
Addressing Common Copper Coating Challenges:
- Dealing with Single-Point Connections:
- Use 0-ohm resistors, magnetic beads, or inductance for connections.
- Handling Copper Coating Near Crystal Oscillators:
- Coat copper around high-frequency emitting sources and ground the oscillator shell separately.
- Managing Dead Zones:
- Define ground vias to address excessively large dead zones.
Optimizing Copper Pour Aesthetics:
- Evaluate the choice between large-area copper pour and grid copper pour based on specific requirements.
- Balance aesthetics and functionality considering heat dissipation and interference factors.
Conclusion:
Copper coating in PCB design, when strategically implemented, offers substantial benefits, including impedance reduction, enhanced anti-interference capabilities, and improved power supply efficiency.
