General rule is 10 to 12 times the thickness of the circuit. This rule holds
well for most circuits up to 4 layers. For simple flex to install you can
actually crease the circuit as long as it is not creased and uncreased in
the engineering phase.

Subject: [TN] Minimum bend radius calculation in a flex circuit


I am on project that requires that I determine the minimum bend radius of a
flex circuit. I have not been able to find out any formulas or calculations
to help out.

I am a mechanical design engineer, so I am not up on all the terminology.
It will of the class "Flex to Install", and will be of the adhesiveless
type. Can anyone help out?

Thanks.

Doug
