Is it for RF? Interesting. Many parallel traces have lower inductance than the same width in a single trace. The bonding, and "z" bends are puzzling though. That looks to add inductance. There's a lot of vias, which I suspect mean that there's a lot of high frequency current flowing, and they want to bond upper and lower ground planes. I've seen traces snaked to add inductance, but I've never seen one like this before! -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
