I. Component Layout Rules Module-Based Layout: Group related components that serve the same function into a module. Separate digital and analog circuits to minimize interference. Clearance Around Holes: Non-mounting holes (e.g., positioning holes): Keep a 1.27mm clearance around them. Mounting holes (e.g., screw holes): Maintain 3.5mm clearance for M2.5 screws and 4mm for M3 screws. Avoid Vias Under Components: Do not place vias under horizontal...
Selecting the right PCB material is not just a design choice—it directly impacts signal integrity, thermal performance, manufacturability, and long-term reliability. For engineers and sourcing professionals, material selection often becomes the hidden factor behind project success or failure, especially in high-frequency, high-speed, or harsh-environment applications. This guide breaks down how to choose PCB materials based...
Circuit boards play a key role in making sure electronic products work properly. They provide structural support and link all the electrical parts together. Whether it’s in smartphones, laptops, or household devices, none could operate without a PCB. This guide will introduce you to the components of a printed circuit board and help you understand the manufacturing process....
1. What is a Motor Controller? A motor controller is an electronic or electrical device used to regulate the speed, torque, and position of a motor. It can automatically or manually start, stop, and protect the motor from issues like overloads. Without a motor controller, motors would be at risk of electrical faults due to the high...
