Hello, I have to perform a simulation of the deformation of an electronic board.
I found in the Solidworks library reinforced Epoxy. Do you know if these parameters can be suitable?
Thank you
What material is your card if it's the same material there's no problem
otherwise knowing the material for a simulation study is a minimum I think

@gt22, I think that's exactly the point of his question:)

Knowing that there is also a copper film, I don't know if this criterion should be taken into account, and if so, if it should be considered as a composite material

Epoxy reinforce c is for power supply cards.
The starting point for the manufacture of a double-sided circuit is a sheet of epoxy resin bonded between two thin layers of copper.
The thicknesses of the dielectric formed by the resin are generally a multiple of 50 μm. The most common thicknesses of copper sheets are 9, 18, 35, 70, 105 μm. Larger thicknesses of copper can be used for so-called drain layers that have a heat dissipation function , while the other layers are intended to establish either an electrical bond between two pads (signal layers ) or a bond to a given potential (ground layers ).
The most commonly used insulating material is an epoxy resin called FR-4 for low-frequency applications. For higher frequency applications, other types of resins are used such as polyimide resin or Teflon-based materials.

Hello, as indicated on Wikipedia, it is indeed epoxy reinforced with glass fibers:

For me if you want to push a study like that you would have to push the vice to make an assembly between an epoxy sheet and the copper stick on it (the standard single sided electronic board 1.6mm with the copper)

@Gerald,
Yes I was also thinking about this situation, but then to model the non-slip attachment of the copper plate on the epoxy plate ... We really enter a bi-material as on this video: https://www.youtube.com/watch?v=FKElP3ZtNcw
@charles.capraro
Is it a simple bending deformation?
But already I think you have to know the number of layers.
if it's a transformer with condo for a power supply card -> epoxy power supply from solidworks very good
If it's a board with micro controller Fpga etc... -> the beginning of a great research adventure. 1-2-3-4 ... layer?

in reply @ Aurélien
Doing a simulation study without knowing the material is heresy
This is a prerequisite and the basis of a simulation study
@+ ;-))
See this link among others
http://www.pcbelectronics.fr/index.php
and who + is possible to contact them to find out the materials used
@+ ;-))
well I add a layer after research on the complex electronic board I entered the material values which would be for a 4 layer
