Shield Can EMC protection screening products from Harwin are now available in kit form, enabling designers to rapidly construct PCB cans at minimal cost for development purposes.
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, engineers have to typically order bespoke cans without being 100% certain of their eventual requirements, thus incurring costs and creating delays. With this kit, a can is easily and effectively created in minutes, with no special tools or experience required.
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.
