IPC Class 3 Design Guide
The Sierra Circuits IPC Class 3 Design Guide helps you design high-reliability PCBs for electronics that won’t fail.
Which class of board to choose? IPC class 2 or IPC class 3 standard? Does it really make any difference? Are manufacturers solely responsible for the board quality? Do designers play any role in it? If you have all these questions on your mind then this design guide will help you clear up that ambiguity.
This design guide helps you design and build PCBs for precision and reliability:
- IPC guidelines for manufacturing defects
- IPC standards for assembly processes
- Common differences between the classes
- IPC documents to set the level of acceptance criteria
Designing IPC Class 3 PCBs for precision and reliability
When we talk about IPC classes, we are speaking about the level of inspection that defines the manufactured board’s precision and reliability. The three classes are categorized based on the criticality of the application, the tolerances to the harsh environment, and so on. In short, the three classes determine the quality of the board. With IPC class 3 being the highest in quality and class 1 being the lowest. The other important thing that we would like to state here is that we cannot solely explain IPC class 3 without also understanding the other two classes. Hence, in this design guide, we mention class 1 and class 2 for your better understanding.
Sierra Circuits offers internal quality review systems that guarantee zero-defect boards. We also provide engineering support to verify if your design is IPC class 3/A or mil-spec compliant.
