PCB Design Best Practices
- Follow a specific order when designing PCBs, progressing from left to right and top to bottom.
- Ensure appropriate width and spacing of traces, matching capacitor pad spacing with lead pin spacing.
- Minimize traces and maintain straightforward routing in the wiring diagram design.
- Verify correct pin arrangement sequence and maintain reasonable component spacing.
Wiring Direction:
Align component arrangement with the schematic diagram and follow the circuit diagram’s line direction for wiring. Verify production, debugging, and repair processes while meeting circuit performance requirements.
Efficient Wiring Design:
Strive for minimal external connections, meet charging requirements, and design for easy installation and maintenance.
Component Arrangement:
Ensure a neat, uniform layout for components, focusing on aesthetics and structural integrity.
Inlet and Outlet Terminals:
- Keep the distance between end leads around 2 to 3/10 inches.
- Concentrate incoming and outgoing lines on one or two sides without dispersing them too much.
Potentiometer and IC Seat Placement:
- Potentiometer: Design for adjusting voltage output or current, position according to installation requirements.
- IC Seat: Ensure accurate positioning of IC pins, align positioning slot correctly.
Resistors and Diodes Positioning:
Choose between horizontal and vertical layouts based on the number of components and board size.
- Horizontal Layout: Ideal for fewer components on a large board.
- Vertical Layout: Suitable for a higher component count on a smaller board.
