Harwin Plc Key Developments

Harwin Delivers Package of Effective Surface Mount EMI/RFI Solutions Designed to Simplify Design and Manufacture

Harwin have announced a package of surface mount products that can be used separately or in combination to deliver an effective EMI/RFI solution. All the products contained within Harwinâ s popular EZ-BoardWare range are designed to take advantage of surface mount technology, simplifying and speeding manufacture, reducing costs and increasing quality. EZ-BoardWare Shield Cans are simply pressed onto pre-positioned surface mount EZ-Shield Clips forming a Faraday cage around sensitive ICs and electronic circuitry. This saves expensive secondary assembly and facilitates rework. A range of can sizes and clips are available. Attenuation performance up to 24dB can be achieved, depending on frequency and configuration. The cans have a simple, five-sided box design, which is mechanically robust and more cost-effective than fence and cover types. Used with EZ-BoardWare Shield Can Clips, EZ-Shield Cans resist vibration and remain securely retained on the PCB. As well as simplifying maintenance and adjustment, auto placement of the EZ-BoardWare Clips eliminates post-assembly soldering and de-soldering, significantly reducing PCB damage caused by local overheating on the board. In order to facilitate and expedite design, Harwin now offers these EZ-BoardWare EMI/RFI protection screening products in kit form, enabling designers to rapidly construct PCB cans at minimal cost for development purposes. The low cost kits comprise two 80mm x 60mm x 0.3mm thick Nickel Silver sheets that are pre-scribed on a 5mm grid to allowing easy cutting and forming, enabling the user to produce a shield can of the required dimensions. EZ-Shield Can Clips which hold the cans securely in place are also included.

Harwin Launches New 10A Hi-Rel Power Connector

Harwin has launched a family of high density power connectors that can handle currents up to 10A. Based on a 3mm pitch, the new M300 connectors are designed for rugged environments and withstand twice the number of operations as older generation products. M300 connectors feature a 4-fingered Beryllium Copper female contact which delivers superb electrical and mechanical performance. Devices suit 18 to 22AWG applications and are designed for use in temperatures of between -65 and +175degC and are rated for 1,000 operations. They pass shock (EIA-364-27: 100g 6ms No Discontinuity >1us and vibration) (EIA-364-28 10g No Discontinuity >1us) testing. Jackscrews are available for extra security. Other features include keyway polarisation and identification of the #1 position, and the connector bodies are moulded in environmentally-friendly material. To aid design activities, Harwin provides CAD models and test reports, and live technical support is always available.

Harwin Expands Range of EZ-Spring Contacts with Different Contact Styles and Heights

Harwin Plc has expanded its range of EZ-Spring Contacts with different contact styles and heights. Part of the EZ-BoardWare range of PCB hardware products, the surface mount Spring Contacts - also known as Spring Fingers or Grounding Contacts -- are now available in 15 different sizes, ranging from 1.7mm to 7.25mm free height (1.20mm to 6.35mm minimum working height), and are suitable for both vertical and horizontal contact actions. Designed for easy assembly onto PCBs, EZ-Spring Contacts are used as grounding or shielding contacts in contact with metal frames or shields, or even for general electrical connection between PCBs or similar. Mounted in a row, the contacts can provide an excellent RFI shielding connection for metal doors or other cabinet enclosures. The contact design ensures positive contact with the mating surface, and is tolerant to both wiping and sliding action. Individual clips are supplied in tape and reel packaging for automated placement, and reduce manufacturing costs by eliminating time-consuming secondary assembly operations.
