For anyone having problems in burning boot loader in an Atmega328, the burnt atmega328 should be the most common tricky problem. some makers users are looking for an alternative to replace it. Now some say that Atmega328P-PU could be a great alternat

If the package of both parts is the same and the Pin layout is the same you can replace it.

It appears that the flux was burnt over the wave process. I have seen this before. Are you using convection heat?

We use tweezers to pick burnt 'peelable' mask. That stuff stuck in the unfilled PTH is a mature female dog.
