Default Routing

If PC A on Subnet A pings PC B on Subnet B and has to go through 5 routers, how many times does the Source Mac address change.
I am under the understanding that once the TCP header leaves the PC A it (TCP Header/packet ) gets updated as it is leaving the exit interface of the first 1 router. But what happes, when it reaches to the 5th router.
Does the header ( Source Mac Address) change when it goes from Router to router?
