Introduction to PCB assembly

PCB assembly refers to the process of attaching electronic components to a printed circuit board (PCB) to create a functional electronic device or product. The PCB serves as the foundation, providing the electrical connections between components. PCB assembly involves several key steps:

1. Solder Paste Application
2. Component Placement
3. Reflow Soldering
4. Inspection and Testing
5. Final Assembly and Packaging

China is a global leader in PCB manufacturing and assembly, with many factories located in major industrial hubs like Shijiazhuang and Shenzhen. These cities offer access to skilled labor, advanced technology, and efficient supply chains.
