How to decide the layout and wiring on a board less than 16cm²? In the camera module design video released today, Director Chen from Zhibo Technology will take you further into the essential design principles of small PCBs. Through the explanation of this case, everyone will master the design methods of such small boards, eliminating the fear of small boards. Let’s take a look together!

Case Overview:

This case uses the FH8556 sensor designed camera module; an 800W pixel high-definition camera with a typical size of 38mm×38mm. The case includes modules such as the Sensor chip part and three power supply modules. In the PCB design process, we focus on explaining the four-layer board stacking design, 20H principle, differences between positive and negative films, modular layout, modular wiring, wiring optimization, and post-processing of PCB design standards, helping students understand and advance their PCB design methods and practical experience more easily.

Learning Objectives:

1. Understand the overall requirements for FH8556 camera module design
2. Master the 4-layer PCB design process and post-processing methods
3. Master interactive layout and modular layout techniques
4. Master PCB rapid wiring ideas and techniques
5. Master BGA fan-out and rapid exit methods
6. Master MIPI interface camera design methods
7. Master high-speed differential wiring methods
