Why did it work this time?
- The heaters have a preferred side - There seems to be a blueish grey tinge on one side while the other is much more reflective. All the failed tests were set up to be soldered on the highly reflective side. The speckling from the flux that happened in the first 2 tests didn't happen on the "blue" side.
- Thanh soldered in between the wick and the heater
Issues - during the failed tests, the reflective side placed on the bottom was scratched.
