Over the years, the IPC Task Group has regularly updated the document to address the shifting electronics landscape:
If you are designing a consumer gadget, Rev. C may be sufficient. However, if you work in automotive, medical, or aerospace, you must use Rev. D, as it addresses high-reliability soldering and harsh environment testing. ipc-7095 pdf
This is why most people hunt for the . The standard provides x-ray inspection guidelines, including: Over the years, the IPC Task Group has
You need to read up on . It covers everything from via-in-pad designs to the nitty-gritty of reflow profiles for high-density interconnects. D, as it addresses high-reliability soldering and harsh
