Hi all,

I am interested in understanding the physical standards of HDI PCBs compared with conventional PCBs.

Typically, overall thickness for conventional PCBs can be specified from a range of standard thicknesses e.g. 0.6mm, 1.0mm, 1.6mm. Within these thicknesses a range of prepreg, cores and copper are specified to fit the functional requirements of the board.

Is there an equivalent range of overall thickness of the board that is common in HDI boards. And are there standard material configurations of copper and dielectric, of given thicknesses, to achieve these overall thicknesses?

Thanks in advance for any thought on this.

David
