Layer Stackup - Getting Geometries

mnpebm , 05-25-2017, 08:35 AM
When I send my impedance requirements, reference layers, and number of layers to the bare board MFG, in order to get geometries, don't I also have to specify what board material(s) are appropriate? Or do I just find and specify an IPC spec?

Usually, the PCB manufacturer will suggest material based on their stock.

I am probably making too much of this, but doesn't the PCB manufacturer need to know what assembly soldering temperatures might be? Would they just look at my gerber files and impedance requirements and then suggest board material?

No, they do not need to know assembly soldering temperatures.
