Extended range of SMT Spring Contacts

Spring Contacts from Harwin

 

Harwin, the leading hi-rel connector and SMT board hardware manufacturer, has expanded its EZ-BoardWare range of PCB hardware products with nine new EZ-Spring Contacts. Also known as Spring Fingers or Grounding Contacts, these devices are designed for easy assembly onto PCBs, and are used as grounding or shielding contacts, in contact with metal frames or shields. Suitable for both wiping and sliding action, the individual clips are supplied in tape and reel packaging for automated placement, and reduce manufacturing costs by eliminating time-consuming secondary assembly operations.

A significant addition to Harwin’s existing range RFI/EMI spring contacts, the new devices are available in a variety of different styles. Uncompressed heights of between 1.7mm and 7.0mm provide excellent design flexibility, and good spring properties provide excellent electrical connection/grounding to be made between a PCB and various other electronic components - other PCBs, speakers, fans, aerials, shields etc – even if the equipment is subject to vibration. A variety of plating finishes, including gold and tin are offered.

Comments Product Manager, Paul Gillam: “These EZ-Spring Contacts take up minimal space on a PCB and are mechanically strong, capable of providing a good electrical connection that can be easily mated and separated many times. More, they provide a low cost solution being auto-placeable by industry-standard equipment.”

EZ-Spring Contacts are suitable for use in virtually all industry sectors across a wide range of products including mobile and smart phones, sat navs, MP3 players, cameras and video systems, tablet PCs, laptops, PCs, brown and white goods, medical and industrial equipment.
