Solder profiles and background info

Initial heater test[edit]


Programs used[edit]

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

Final profile[edit]


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.


The second run of 0603 resistors was a success
Some very fine pitch ICs

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.
