Relationship Between Current and Line Width in PCB Design

In PCB design, trace width is one of the fundamental parameters that directly affects the electrical performance, thermal reliability, and manufacturing quality of a circuit board. When current flows through a PCB trace, the conductor generates heat due to electrical resistance. If the trace width is insufficient, excessive temperature rise may cause: Copper trace overheating...

Multilayer PCB Manufacturing Process: A Complete Step-by-Step Guide

With the increasing demand for higher circuit density, faster signal transmission, and more complex electronic functions, multilayer printed circuit boards (PCBs) have become a fundamental technology in modern electronic products. Unlike single-layer or double-sided PCBs, multilayer PCBs integrate multiple copper layers and insulating dielectric materials into one compact structure, allowing engineers to achieve complex routing,...

PCB for SMT (Surface Mount Technology): Choosing the Right PCB for SMD Components

With the rapid development of electronic products toward miniaturization, higher integration, and automated manufacturing, Surface Mount Technology (SMT) has become one of the most widely used PCB assembly methods in modern electronics. Unlike traditional through-hole components, Surface Mount Devices (SMD components) are mounted directly onto the surface of a PCB, allowing manufacturers to achieve: Higher...

PCB Layout Planning – Packages and Routing

PCB layout planning is a critical phase in the design process, enabling engineers to save time and ensure a structured approach to package management, component placement, and routing. Proper planning ensures that the design meets electrical, spacing, and physical requirements before moving to the actual layout stage. This article explores key aspects of PCB layout planning, focusing on footprint management, routing strategies,...
