EMC Shielding Products

Harwin's range of EMC Board-Level Shielding covers 4 product types, each with their own advantages over the traditional shielding and grounding solutions.

EMC Shield Cans

Harwin specialise in Nickel Silver cans in a simple 5-sided shape. Designed for use with Harwin's Shield Can Clips, no soldering is required on the can for easy fitting.

  • Eliminates hot spots due to hand or selective soldering as a second operation. Cans are assembled with a simple push operation.
  • Simple to rework - just pull the can out the clips to access the board underneath. Replace the can just as easily once finished.
  • Single-piece construction saves costs over complex fence-and-lid cans.

EMC Shield Can Clips

Harwin's wide range of Shield Can clips are all Surface Mount, supplied in Tape and Reel packaging for automated assembly placement.

  • Clips are assembled at the same time as all other SMT components on the board - eliminate secondary soldering operations.
  • Wide range of shapes to cover shield thicknesses from 1mm down to 0.17mm.
  • Low profile options for minimal height cans.
  • Variety of insertion force, including vibration-tested versions.
  • Improves signal integrity by eliminating through-holes that interfere with the ground plane.

Shield Can Kit

Everything you need to make your own customized size of shield can! Award-winning kit includes two pre-scored sheets, 24 Shield Can Clips and an instruction sheet. Just add a ruler and a pair of scissors.

  • Scored at 5mm intervals - simply cut the blank along the scores, then fold the 4 edges down.
  • Ultimate flexibility for developers - try out different sizes for prototyping and development work.
