Copper C110 and the Isola 370HR laminate from this library; the layers conduct in parallel along the board and in series through it (boardStackup.ts). Its two 0.0028 in trace layers cover little of the board and are left out; vias are ignored. Mechanical values are the bare laminate's.
Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Questions Is Aluminum 2024-T351 stronger than PCB Board FR-4, 2 copper planes? Aluminum 2024-T351 is stronger: its yield strength is 324 MPa against tensile strength 315 MPa for PCB Board FR-4, 2 copper planes (3%).
Which is stiffer, Aluminum 2024-T351 or PCB Board FR-4, 2 copper planes? Aluminum 2024-T351 is stiffer: Young's modulus 73.1 GPa against 23.9 GPa for PCB Board FR-4, 2 copper planes, so the same part in Aluminum 2024-T351 deflects less under the same load.
Which expands less with temperature? PCB Board FR-4, 2 copper planes expands less: 13.5 µm/m·K against 22.9 µm/m·K for Aluminum 2024-T351.
