17-06-2011: Sprinting bears fruit: 14 issues found
Since the Scrum sprint to quickly debug the design with four engineers, already fourteen hardware problems have been found. Many are small bugs, but it also has been found that the SFP serial inputs are not usable as the Tx and Rx part are swapped.

11-04-2011: small production finds assembly problems
To allow other people to start developments for the VFC card, ten additional boards have been produced. During the assembly, problems with the FMC connectors appeared that could be circumvented by using a thicker stencil (that will apply more solder) and then reworking some capacitors manually.
