Shield Can Kit
Shield Cans now available in kit form for fast, low cost development - ‘build your own’ EMC protection
Shield Can EMC protection screening products from Harwin are available in kit form, enabling designers to rapidly construct PCB cans at minimal cost for development purposes.
Clip and Can advantages
Harwin’s Shield Cans are simply pressed onto pre-positioned Surface Mount Shield Clips, forming an EMC cage around sensitive ICs and electronic circuitry. This saves expensive, labour-intensive secondary assembly and facilitates rework. A range of standard Can and Clips sizes are available. However, during development and test, typically engineers have had to order bespoke cans without being 100% certain of their eventual requirements, incurring costs and creating delays.
Now, a can may be created easily and effectively in minutes, with no special tools or experience required.
Simple and fast prototyping
The low-cost kit comprises two 80mm x 60mm x 0.3mm thick Nickel Silver sheets that are pre-scribed with a 5mm grid. This allows easy cutting and forming, enabling the user to produce a shield can of the required dimensions. Auto-placeable Shield Clips are also included, to hold the cans securely in place on the PCB.
Comments the Product Manager: “Product testing has confirmed that the nickel silver material provides effective and useable shielding, with up to 24dB attenuation achieved, depending on frequency and configuration. We believe that the kits will save costs and time during development, and enable an optimised EMC solution to be found.
The Shield Kits complement Harwin’s standard clips and cans, which offer a highly cost effective method of screening. Auto-placement of the related clips allows post-assembly soldering and de-soldering operations to be eliminated, leading to significant reduction in PCB damage. Applications will be found in many markets, ranging from Consumer Electronics through to the Industrial, Instrumentation and Control Systems environments.
