HDI

Motivation – Going forward with HDI

• Simplify Routing

• Reduction of the number of layers

• Improve control of signal integrity

• Drive cost down

• Improve EMI

• Miniaturization

• Faster time to market

 Advantage with HDI

• Number of layer can be reduced from 12 to 10 – saving 1 signal layer and one GND layer

• Bring signal layers closer together and reduce inductance to ground. Will simplify via structure and improve signal integrity

• Reduce overall thickness of the board and reduce also the inductance of the PTH vias.
