board level shielding (bls)

Reduce, Limit, and Control EMI

Due to a growing need for thinner devices with multiple antennas, higher data rates, and increased operating frequencies, modern mobile devices require better solutions for reducing or limiting the effect of electromagnetic interference (EMI).

Board level shielding: EMI shields from TE. These shields are stamped one-piece and two-piece metal cages that help provide isolation of board level components, minimize crosstalk, and reduce EMI susceptibility without impacting system speed. Although we use standardized materials and offer common design features and options, every BLS project is customized to fit your design requirements.

Board Level Shielding Manufacturing (English)

Board Level Shielding (BLS) is manufactured in our Qingdao Plant. BLS is made in one continuous, fully automated line where the product is first stamped, 100% inspected, and packaged for shipment.
