= Programs used=

Final program:
<pre>
0 15s 40°C
1 150s 150°C
2 90s 215°C
3 90s 265°C
4 40s 265°C
5 120s 40°C
</pre>

= Final profile =

[[File:wetrun3.png]]

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.

= Results =
[[File:Smd_reflow_soldered_resistors.jpg|thumb|center|The second run of 0603 resistors was a success]]

[[File:smd_reflow_soldered_ics.jpg|thumb|center|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.

Koenraad:

Whitespace is the HQ of Whitespace. It's located in Blekerijstraat 75 Gent, '''room 1.21'''. Also check out the [[Blueprints]]. For snail mail, swag, bills, death threats, bom letters, address to bus 13.

This video shows you where to go after arriving at the gate:
