The IPC classifications set the rules to follow when designing a printed circuit board. And between Class 2 and Class 3, the design requirements are fairly different. How much do you know about the different design rules for IPC Class 2 and Class 3? Take the quiz and find out!
Congratulations, you sure know a lot about the different design rules between IPC Class 2 and Class 3. We can help you design and build your IPC Class 3 PCB.
It looks like you could still learn a thing or two about the different design rules for IPC Class 2 and Class 3.
