The Role and Addition Method of Process Edge and MARK Point in PCB Design
Jul 25,2025
I. Why does PCB design require process edges and MARK points? 1. The role of process edge The Fiducial Edge or Process Edge is a blank area reserved at the edge of the PCB, mainly used for: • Production fixture positioning: SMT placement machines and other equipment need to fix the PCB through the process edge to ensure processing accuracy. • Prevent damage to edge components: Avoid direct contact...

Understanding DFM Checks in PCB Design
Jul 31,2025
1. What is Design for Flow (DFM)? Design for Manufacturability (DFM) involves taking into account factors such as manufacturing processes, costs, and yield during the PCB (Printed Circuit Board) design phase to ensure the design can be produced efficiently and cost-effectively. The goal of DFM is to reduce design defects, improve production efficiency, lower manufacturing costs, and ensure product...

PCB Trace Width vs. Current Rating – Why Engineering Precision Matters in High-Power Design
Jan 06,2026
In the intricate world of printed circuit board design, few relationships are as fundamentally critical yet frequently misunderstood as the connection between trace width and current carrying capacity. Every day, engineers and designers face the same crucial question: "How wide should my PCB traces be to safely carry the required current without compromising reliability or performance?" The answer...
