[edit] Initial heater test
[edit] Programs used
Final program:
0 15s 40°C 1 150s 150°C 2 90s 215°C 3 90s 265°C 4 40s 265°C 5 120s 40°C
[edit] Final profile
Comparing this profile to the 'ideal' solder profile, the main difference is that we do not dwell on the 'pre-heat' phase (ie. 150-200°C). This is because we could not get the temperature to rise fast enough, so we were forced to stick to a steady, slow ramp.
[edit] Results
The results of the final profile were excellent. The main restriction of this technology is the precise application and dosing of the solder paste, and the placement of the components. We will experiment with using stencils next time. This should improve success rate significantly.
