In the PCB industry, ​​EMS (Electronic Manufacturing Service)​​ also known as ECM or professional electronic manufacturing services. Refers to a company that provides a comprehensive range of services to take a printed circuit board (PCB) from a design file to a fully assembled and tested...

When you take apart a phone or smartwatch, you'll often see a flexible circuit board inside—an FPC (flexible printed circuit board). Many newcomers to the industry are curious: "What materials make FPCs so flexible and bendable?" In reality, the performance of an FPC depends entirely on its ra...

In the design and manufacture of printed circuit boards (PCBs), signals and power are routed between different circuit layers through vias, and via design is a crucial step. Different types of vias (through, buried, and blind) are used to provide electrical connections, mechanical support, and therm...

Printed Circuit Boards (PCBs) are the backbone of modern electronics, powering everything from smartphones to aerospace systems. As the demand for advanced electronics grows, manufacturers worldwide seek reliable, high-quality, and cost-effective PCB production solutions. ​​China has emerged as the...

​What is PCB immersion gold?​ PCB Immersion Gold​​ (also known as ​​ENIG – Electroless Nickel Immersion Gold​​) is a surface finish process used in printed circuit board (PCB) manufacturing. It involves depositing a thin layer of gold over a nickel layer on the copper pads of a PCB through a c...

As electronic devices progress toward miniaturization and higher performance, chip packaging technology for printed circuit boards (PCBs) continues to evolve. Ball Grid Array (BGA), a high-density, high-reliability packaging technology, has become a key technology in modern PCB design. This article...
