Main PCB board with 3 CPU on it (including GPS).
Soldering kainda a problem - for indium alloy (In60Pb40)it is very time consuming, with indium(In60Pb40) soldering paste is less available and expensive, with indium (In100) paste is low strength (SMD components can not withstand good vibration), plus is 155C max, plus it is less sticky.
For ground station and CS prototype used Sn60Pn40. For relatively simple board process takes 2 hours for components list, 1 hour for manual paste distribution, 1 hour for placing SMD, 7 min in oven. For InPb soldering it will take around 2+6 hours.
And it will be less video from now on – next CubeSat flight software.
