EMI
/ RFI Shielding Laminates
Orion
Industries Inc specializes in designing unique laminated
shields applying selective die cutting techniques for cost
effective solutions. Orion has been awarded two patents for
advanced design in shielding enclosures.
Shielding
laminates 101:
Unfortunately,
plastics are virtually transparent to EMI and RFI signals.
To shield against unwanted interference, a barrier of
electrically conductive material is needed, many times with
some sort of grounding mechanism. Most of our materials
consist of a metal foil (usually, copper or aluminum)
laminated to an insulating substrate, which prevents
unwanted grounding of circuits. The insulator also adds
structural integrity to the shield, since the foil is very
thin (0.002”-0.005”). Typical designs may also
incorporate areas where the insulator is removed for
grounding.
Our
material specialists will assist you in determining the most
appropriate material for your application. The design
considerations will most likely include:
1.
Puncture resistance
2.
Agency approvals, UL flammability
3.
Temperature range
4.
Dielectric strength
5.
Grounding options
6.
Environmental concerns
7.
Thickness
constraints
Orion
Industries has been producing
shielding laminates for over twenty-five years.
