The EMI Shielding Supply Chain
Who does what in board-level EMI shielding — from the engineers and labs that plan it, to the stampers and etchers that tool it, to the EMS and distributors that scale it. A neutral map to help buyers and design engineers navigate the chain.
Read it as a journey: how a shield moves from design to volume →
Design Inception
Simulate, plan, and budget the shieldingWhere EMC strategy is set: hardware and EMC engineers model shielding effectiveness, plan board partitioning, and line up the compliance path (FCC, CISPR, IEC 60601, MIL-STD-461, DO-160) before a board exists.
Ansys (HFSS)
North America3D electromagnetic field simulation (HFSS) used to model board-level shielding effectiveness and cavity resonances before tape-out.
Dassault Systèmes (CST Studio Suite)
3D EM simulation widely used for EMC, antenna, and shielding analysis of electronic assemblies.
Element Materials Technology
Accredited EMC/EMI compliance and MIL-STD-461 / DO-160 testing across a global lab network.
Intertek
EMC testing and certification for commercial, automotive, medical, and military/aerospace electronics.
Keysight Technologies
North AmericaEM simulation (PathWave/EMPro) and EMC test instrumentation used through design and pre-compliance.
UL Solutions
North AmericaAccredited EMC compliance testing and certification (FCC, CISPR, IEC).
Washington Laboratories (WLL)
North AmericaEMC engineering consultancy and accredited test lab; pre-compliance and design support.
Prototype & Sample
Tool, sample, and pre-compliance testWhere the shield gets real: stampers and etchers tool the can, quick-turn assemblers build boards, and accredited labs run pre-compliance scans. Custom footprints and fast tooling matter most here — POCONS’ lane.
AK Stamping
North AmericaStamped board-level shields and EMI shielding hardware.
CEP Technologies
North AmericaCustom EMI shields produced with progressive-die stamping.
Fotofab
North AmericaPhoto-etched EMI/RFI shields with low/no minimums and quick-turn lead times.
Laird (Qnity Electronics)
North AmericaBoard-level shields in one-piece, two-piece, and custom-stamped configurations; long-standing category leader. Now part of Qnity Electronics (spun off from DuPont, Nov 2025; formerly Laird Performance Materials).
