The space probe Rosetta was built by the European Space Agency (ESA ) with the objective of reach and study Comet 67P/Churyumov-Gerasimenko. Was launched on March 2004 from Kourou. To place it on the required orbit to rendezvous with Comet 67P/ Churyumov-Gerasimenko it received four gravity assist manoeuvres: 3 from Earth (4 March 2005, 13 November 2007 and 13 November 2009) and 1 from Mars (25 February 2007).

The performance of PCB systems are sensitive to variations in the plating thickness of its vias, depends on the current/time in the copper plating bath and the throwing power. Insufficient plating thickness reduces the mechanical and thermal properties of the board and may lead to fatigue or overstress cracking, such us corner cracking and barrel cracking described below.
