In the world of printed circuit board (PCB) manufacturing, not all boards are created equal. Depending on your application, your PCB may need to meet IPC Class II or IPC Class III standards — two of the most widely recognized quality classifications in the electronics industry. Understanding t...

Box Build Assembly​ (often just called "Box Build") is the final stage of electronic manufacturing where all the individual components, sub-assemblies, and the main printed circuit board (PCB) are integrated into a complete, functional product enclosure or "box." Think of it as the difference betwee...

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...

​​1. What is AOI inspection？​   AOI (Automatic Optical Inspection) is a core quality inspection tool for SMT (Surface Mount Technology) production lines. Using high-resolution cameras, multi-angle LED lighting, and intelligent image analysis algorithms, it performs real-time visual inspection...

​​I. Detailed explanation of the complete process of PCBA burning​​ PCBA burning is the process of writing firmware into the chip to ensure that the hardware can work properly. The complete burning process usually includes the following key steps:   ​​1. Preliminary preparation ​ · ...

1. ENEPIG Technology Overview   ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) is an important technological breakthrough in the field of PCB surface treatment in recent years. This process provides an ideal surface protection solution for modern high-density interconnected PC...

Spot welding technology   Spot welding is a technology that connects metals by local heating, and is mainly used for connecting thin sheet metals. Its working principle is to use two electrodes to apply high voltage current in a short time (usually 0.01-0.5 seconds) to make the contac...
