The surface treatment of PCBs directly affects their performance, reliability, and production cost. Among the various surface treatment technologies, Immersion Gold (ENIG) has become one of the most widely used and efficient processes.
This article will provide a comprehensive understanding of the PCB immersion gold technology, covering everything from design to
As electronic devices become more powerful, effective heat management is crucial for maintaining performance and longevity. Aluminum-based printed circuit boards (Al-PCBs) offer an efficient solution, thanks to their high thermal conductivity.
This article explores the thermal management technology of aluminum-based PCBs from the perspective of thermal conductivity, analyzing material characteristics, design
OSP (Organic Solderability Preservative) is one such surface finish that has gained popularity in PCB manufacturing. However, how does OSP compare to more traditional surface finishes? What unique advantages and limitations does OSP offer?
This article provides a comprehensive comparison of OSP with other common PCB surface finishes to help engineers,
In electronics manufacturing, selecting the right PCB assembly technology is crucial for product performance, cost, and production efficiency. Two of the most commonly used assembly techniques—Surface-Mount Technology (SMT) and Through-Hole Technology (THT)—each offer distinct advantages and are suitable for different applications.
In this article, we will explore the key differences between
Among the various technologies used for pattern transfer, Laser Direct Imaging (LDI) and traditional exposure technology are the two main methods. Both play a crucial role in PCB production, but due to their distinct technical characteristics and advantages, choosing the right method is essential for optimizing manufacturing efficiency and product
Introduction: Overview of Laser Prototyping Technology
Definition and Development History of Laser Prototyping
Laser prototyping technology is a cutting-edge manufacturing method that uses precise laser beams to cut, engrave, and drill materials to rapidly create high-precision PCB (Printed Circuit Board) prototypes. This technology emerged in the 1970s and has gradually found its
In the manufacturing of electronic products, the printed circuit board (PCB) plays a vital role, and its surface finish has a direct impact on the performance, durability, and cost of the final product. PCB surface finishes are used to enhance solderability, prevent oxidation, and ensure stable electrical connections. As technology
