Harwin's Sycamore contacts are single-piece, SMT socket contacts. They are designed for direct assembly to the PCB, using two terminals to balance on the PCB and the rest of the contact to sit in a hole in the PCB. The design eliminates the outer shell typical on existing two-piece PCB sockets and adds the flexibility of tape-and-reel packaging for automated assembly. They improve on existing SMT sockets by including three points of contact for ensuring signal continuity and improved material choice for durability.
These contacts are ideally suited for PCB layouts with field-replaceable modules with odd-form termination layouts. By locating a Sycamore contact at each termination point, the module can be easily removed and replaced at any time.
Temperature-sensitive components can also benefit from being assembled to the PCB via Sycamore contacts. The Sycamore contacts are subjected to the SMT process along with the rest of the board components. The temperature-sensitive component can then be added after with no exposure to heat from either SMT soldering or post-operation hand solder.
This contact is therefore suitable for the sensor applications industry, such as domestic and commercial gas detection systems, fire alarms, and metering systems.
