If your application requires limits in electromagnetic and/or
electrostatic interference, shielding may be required. Shields are
material around a conductor or group of conductors that limit these factors.
Solid copper is the most common method of shielding. Solid copper shields increase the rigidity of the circuit, and should be included in thickness to bend radius review, and copper shield can be put on one or both sides of the circuit. Solid copper can also cover selective conductors.
An artwork design that relieves much of the copper shield areas by the use of a pattern. Crosshatching helps the circuit to retain its flexibility and can be put on one or both sides. Crosshatch shielding can also cover selective conductors.
Conductive silver can be substituted for the copper for shielding purposes in some applications. Silver shielding is not recommended for a dynamic flexing application due to its brittle characteristic and it may be prone to cracking in severe bending applications. Silver can be a solid or cross-hatched shield and can be put on one or both sides of the circuit. It can also cover selected conductors only.
Note: Contact All Flex staff for additional shielding details and options such as shielding between conductors.
