Surface mount EMI/RFI shield clip
As demand for RFI shielding has risen significantly, the need for an effective way to mount shields has now been addressed by Harwin.
SM PCB sockets in tape and reel packaging
Harwin can now supply the existing range of high reliability surface mount PCB sockets in tape and reel packaging.
"This is often performed after the main automated assembly process using manual secondary soldering operations".
"Not only is this process time consuming and costly but causes further difficulties should reworking become necessary".
Supplied in industry standard tape and reel packaging, Harwin's RFI shield clips are placed on the board and soldered using standard SMT placement equipment.
The shielding can is then fitted during final assembly within seconds.
As it is possible to remove and refit the can a number of times, tuning and rework operations are simplified.
Therefore both initial production and rework costs are significantly reduced.
The Midi RFI clip is designed for shielding cans using 0.3mm thick material: the Mini version is 40% smaller and is suitable for shield cans 0.13-0.23mm thick.
Clips are available in 100% tin plate.
The Midi clip is also available in a beryllium-free copper option, suiting it to applications covered by the WEEE (Waste Electrical and Electronic Equipment) and the End of Vehicle Life Directives.
Harwin's EMI/RFI clips are targeted at telecomms basestations, radiocomms, data processing and in-car entertainment systems.
Previous devices have been successfully used in diverse applications such as the Bowman military radio project and automotive satnav/DVD players.
