In a message dated 8/13/2002, you write: To me, it's sort of funny in that it just says that the Creepage and Clearance distances do not apply on inner layers of void free PCBs. That's nice; but I can't find where a distance is specified. I mean, I would think that there should be some

Hi all, I could have sworn that I read somewhere in EN 61010-1 that creepage distances on internal layers of void free PCB boards were reduced from the normal distances. For the life of me, I can't find the statement. I also seem to remember that there was no hard, fast number given. So,

Amund, According to 47 CFR 15.101, you source is correct. The cautionary note here is that: The receiver is exempt, but the electronics after the receiver are probably not. The FCC would see your GPS as a composite device and the digital device would be subject to probably either verification
