As circuit board manufacturers, designers often ask us about the difference between IPC Class 2 and Class 3. Class 1 does exist although we rarely produce boards that fall into this classification. Most of the time, even if the end-use of the product only requires Class 1, we will make it Class 2 just to ensure a better performance.
