Multilayer – When it pays to switch to HDI

The presentation shows the optimization possibilities of the High Density Interconnect technology on the layer structure of a high speed FPGA board. Using the example of a 12-layer multilayer with vias as a Viain pad, it will be explained where the cost-driving manufacturing effort is hidden and what alternatives are available with HDI technology. With the optimal use of microvias, the following aspects are improved during a redesign:

  • Reduction of the production costs of the printed circuit board
  • Improvement of the reliability of the system
  • Use of current footprints with higher pin density for a circuit update
