| Apr 8 at 19:55 | comment | added | Hearth | I'm not convinced that having exposed copper does anything for tombstoning. The thermal impedance of the soldermask is pretty insignificant. | |
| Apr 8 at 19:20 | comment | added | Vincent | Yes, I was talking about thermal reliefs. It seemed to me that the question was about the particular arrangement of exposed copper on certain traces = increasing thermal dissipation (that's what the OP was suggesting). | |
| Apr 8 at 17:59 | comment | added | Andrew Morton | Were you perhaps thinking of thermal reliefs rather than the increased current capacity due to greater conductor cross-section that's relevant to the question? | |
