Introduction Gold fingers are gold-plated conductive contacts located along the edge of printed circuit boards (PCBs), serving as critical interconnection points for signal transmission and power supply between the PCB and external devices or motherboards. These components, named for their finger-like appearance and gold plating, are particularly prevalent in computer Read more
Introduction As the automobile transforms from a purely mechanical means of transport into a “mobile intelligent terminal” integrated with hundreds of smart sensors, its internal electronic and electrical architecture is undergoing a revolutionary change. At the heart of this transformation lies the Automobile PCB (Printed Circuit Board)—a seemingly inconspicuous yet vital component. Read more
Introduction Screen printing, also known as silkscreen printing, is a fundamental process in printed circuit board (PCB) manufacturing that applies identifying markings, symbols, and labels onto the board surface. This critical step occurs after solder mask application but before surface finish and component assembly, serving as the primary visual guide Read more
Introduction Immersion Tin (ImSn) is a critical surface treatment technology for printed circuit boards (PCBs) that deposits a thin, uniform layer of pure tin onto copper surfaces through a chemical displacement reaction. This process creates a protective coating that prevents copper oxidation while providing excellent solderability. As electronic devices evolve Read more
Introduction The evolution of digital health is expanding the frontier of medical-grade wearables, moving beyond the wrist to more intimate monitoring applications such as continuous glucose sensing, cardiac patches, and smart analgesic systems. Central to these advancements is the Medical wearable PCB, which must maintain safe, direct, and often continuous contact Read more
PCB are indispensable components in almost all electronic products. To assemble products according to required configurations, the core PCB is sometimes manufactured by the product owner, and in most cases by the supplier. But when it comes to manufacturing, one of the most common questions is: How much does a Read more
Introduction PCBA cleanliness is a critical quality indicator in modern electronics manufacturing, directly impacting the long-term reliability and performance stability of electronic products. During the assembly process, residues from solder paste, flux, and other process materials remain on the PCB surface. Under specific environmental conditions, these contaminants can lead to Read more
Introduction A PCB module is a core component in modern electronic devices, referring to an independent circuit unit on a printed circuit board (PCB) that performs a specific function through standardized design. Against the backdrop of increasingly complex electronic equipment, the modular design of PCBs has become a significant trend Read more
Introduction In the realm of modern technology, the world is expanding at an unprecedented pace, with advancements directly influencing our daily activities. Today, numerous sophisticated devices are in use—something unimaginable just a few years ago. Supported by these technological innovations, we continue to enhance our quality of life. From smartphones Read more
Introduction Soldering on PCB is a foundational process in electronics manufacturing and assembly, directly determining the performance, reliability, and longevity of electronic products. As the core method for establishing electrical and mechanical connections between components and circuit boards, soldering encompasses a range of techniques—from automated processes like reflow and wave Read more
