Basic UL Knowledge for PCBs
UL certification plays a vital role in ensuring the safety, reliability, and market acceptance of printed circuit boards (PCBs), particularly in North America and other regulated markets.
Differences Between Leaded HASL and Lead-Free HASL: How to Choose the Right PCB Surface Finish
Hot Air Solder Leveling (HASL) is a widely used PCB surface finish, and it can be divided into leaded HASL and lead-free HASL.
Key Considerations for PCB Design from a Soldering Perspective!
PCB soldering quality is not determined by a single process step, but by the coordinated control of design, materials, equipment, and human operation throughout the entire manufacturing flow.
How PCB Electroplating Ensures Precision, Strength, and Long-Lasting Circuits
PCB stands for Printed Circuit Board, the abbreviated term for printed circuit boards. Typically, conductive patterns formed on insulating materials according to predetermined designs—either as printed circuits, printed components, or a combination of both—are referred to as printed circuits.
Study on Optimization of Solder Paste Printing Parameters Based on Machine Learning
Surface Mount Technology (SMT) is a critical process technology for secondary integration. This technology primarily consists of key processes such as solder paste printing, component placement, reflow soldering, and cleaning.
Types of Printed Circuit Boards
Printed circuit boards (PCBs), born in the 1940s, have seen the development of numerous distinct types over more than seventy years since their commercialization in the 1950s.
How PCB Base Materials Are Inspected and Quality-Assured for Reliable Performance
Copper clad laminates (CCLs) are the foundational materials of printed circuit boards, providing both mechanical support and electrical functionality.
What is a PCB Mark Point? How is It Designed?
Reference points, also known as mark points or optical positioning points, are essential for precise PCB assembly in automated manufacturing. Serving as measurable coordinates for placement machines, these marks ensure accurate alignment of circuit patterns and components across all assembly stages.
Common Pitfalls for Beginners: Clearance Issues in PCB Design
PCB beginners often encounter various pitfalls when starting out, such as common spacing issues: the distance between traces, the distance between pads, and so on. This article will discuss the topic of safety spacing in PCB design.
Advanced Any-Layer HDI PCB Technology for Smartphones: Key Innovations and Manufacturing Breakthroughs
