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. For new productions the layout will need to be modified to allow more spacing between these capacitors. At the same time the JTAG chain that programs the two FPGAs will be split into two seperate chains as there have been some programming problems. The modification work on the layout will start in two or three weeks time.

Currently there are four boards working while an additional eight boards need rework.
