FIELD OF THE DISCLOSURE 
     The present disclosure generally relates to information handling systems, and more particularly relates to electrical connectors. 
     BACKGROUND 
     As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Technology and information handling needs and requirements can vary between different applications. Thus information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, graphics interface systems, data storage systems, networking systems, and mobile communication systems. Information handling systems can also implement various virtualized architectures. Data and voice communications among information handling systems may be via networks that are wired, wireless, or some combination.

As an example, receptacle  787  can be a plated-through via. Receptacle  787  can be electrically connected to one or more of conductive layer s  788 ,  789 , and  790 . The connector body can bear upon a surface of receptacle  787  to position the electrical connector pin relative to receptacle  787 . As an example, the peaks of third arched flexure element  705  and fourth arched flexure element  706  can be positioned to bear upon receptacle  787  at or near a first end of receptacle  787 . The peaks of first arched flexure element  703  and second arched flexure element  704  can be positioned inside an interior of receptacle  787  closer to a second end of receptacle  787  than would occur with a connector pin having only a first contact region rather than first and second contact regions. By providing the first and second contact regions, the electrical connector pin provides multiple points of contact. The multiple points of contact minimize the distance from at least one point of contact to a conductive layer connected to receptacle  787  regardless of the position of the conductive layer along the depth of receptacle  787 . Accordingly, both the magnitude and path length of impedance discontinuities introduced by interconnection  700  can be minimized, and signals conforming to interface protocols requiring higher frequencies can be accurately communicated. 
       FIG. 8  is a flow diagram illustrating a method of manufacture for a connector pin according to an embodiment of the present disclosure. Method  800  begins at block  801 .

In block  809 , the first contact portion is twisted relative to the second contact portion. The twisting aligns the first contact portion substantially in a first plane. The first plane is different from a second plane in which the second contact is substantially disposed. The first plane is different from the second plane by an angular offset. Block  809  can comprise block  810 . In block  810 , the twisting of the first contact portion relative to the second contact portion provides an angular offset between five and ninety degrees. From block  809 , method  800  continues to block  811 , where method  800  ends.
