EMI
Shielding requirements are ever-expanding with the development of
smaller, higher-speed electronics. Magnesium TXM shielding solutions
are lightweight, effective and able to follow complex geometries
combining structural, heat transfer and shielding functionality
into one recyclable component.
Precise Magnesium TXM internal frames, plates, shields and enclosures
provide efficient EMI shielding protection, structural rigidity
and thermal management in a lightweight, recyclable form.
Thin
wall housings provide shielding and impact protection.

MAGNESIUM
TXM SHIELDING SOLUTIONS PROVIDE:
| » |
Injection
moldable geometry: multiple compartment shields, stiffening
ribs, bosses, internal threads, 0.020" nominal walls. |
| » |
Greater
than 85 dB of shielding over a wide frequency range. |
| » |
No
plating or fillers required. |
| » |
High
stiffness: less flex than plastic means better transfer of force. |
| » |
High
thermal conductivity for better heat transfer. |
| » |
Complete
component recyclability. |
| » |
Tight
tolerance molding with excellent flatness and coplanarity. |
