The PCB does degrade a bit, but if you manage to get it right on the first run, it's fine. You shouldn't use these temperatures with a connector - those plastics will melt, but ICs never melted on me yet. | |

Your heatsink on top might work out, but that is hard to answer - depends on your application as well, if the part is not active a lot of the time or isn't loaded with the full current, you might even get away without any heatsinking. And on some parts the ground connection is essential for operation because it actually provides more than just a heatsink. | |
| Jan 6, 2018 at 22:09 | comment | added | eeze | this might need to be a seperate question, but do you think that if i didnt solder the pad, but put a small heatsink on top, do you think that might work? | |
