Background Issues of soldering in reduced gravity
Gas bubbles from PCB Previous experiments
SoRGE ○ Found a problem with soldering in milli-gravity
CLEAR○ Finding a solution to the problem found in Sorge
ApplicationsReparations of components in space
○ Long distance space journeys and space stations

Experiment proposal
Our solutionNon pressurized enviroment
○ Overpressure and sample diffusionGas flow
○ Internal flux of solder
Need for a rocketReduced gravity
