My team is responsible for designing industrial electrical devices. We had successfully designed several devices before. Recently, we are designing products that have to meet IEC 61000-4-4 class A standard. We got ourselves EFT generator for testing. But most prototypes have failed and we need to redesign the PCB then test again. This process costs us time and money a lot until we pass the test.
I assume our design team lack of knowledge in this field.
- How to design PCB to pass the EFT and EMC testing?
- How to debug or troubleshoot?
