Enabling designers to rapidly construct PCB cans at minimal cost for development purposes, Harwin now offers its EZ-Shield Can EMC protection screening products in kit form. To form an EMC cage around sensitive ICs and electronic circuitry, the company's EZ-Shield Cans are simply pressed onto pre-positioned surface mount EZ-Shield Clips. This saves expensive, labour-intensive secondary assembly and facilitates reworking.

Typically, during development and test, engineers have to order bespoke cans without being 100% certain of their eventual requirements, incurring costs and creating delays. Harwin's kit allows a can to be created easily and effectively in minutes, with no special tools or experience required.

The low cost kit comprises two 80x60x0.3mm thick nickel silver sheets that are pre-scribed on a 5mm grid to allow easy cutting and forming, enabling the user to produce a shield can of the required dimensions. Auto-placeable EZ-Shield Can Clips which hold the cans securely in place are also included.

The EZ-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 range from consumer electronics through to the industrial, instrumentation and control system environments.

Paul Gillam, Product Manager, Harwin, commented: “Product testing has confirmed that the nickel silver material used 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 help to enable that an optimised EMC solution is found.”
