serpentine routing pcb

It looks like to add some delays in that path of the signal.

rules for serpentine pcb routing

hi this is tombstone routing done to length match the signals or as mentioned to add some delay.
but generally done to length match the traces.

I want to correct here that it is serpentine routing and the routing I mentioned earlier is trombone (is also a technique used for length matching) and not tombstone (a typo).
the image contains serpentine routing as mentioned by popoyboys

I think that this technique is used to fill the empty places. In fact, the fabrication of such a bord consumes less chimical.

Please correct me if I'm wrong.

Re: Filled area in PCB

hai, assume you have 8 databus processor, in that except d0 all others are more longer. Then to match the speed of the data d7 and d0, you need to do like this zigzag, then only all the data buses will come to same length,

Re: Filled area in PCB

Hi, at what bus frequency, rise time/fall time do we need to start length matching?

thx
