  1. Circumflex ContactorImproving Results People Technology Possibilities Patent Pending

  2. Simple and EffectiveCircumflex • Introducing • A new geometric concept for contacting balls that radically increases BGA contacting performance • A new exceptionally elastic metal alloy used for extension or torsion spring designs that resists solder buildup applied for: • Increasing contact pin life • Extending run times between cleaning • Geometrics Mechanical/Electrical Advantages • Making contact just below the equator and encircling the ball on a large surface area provides a highly repeatable low resistance connection • Electromechanical contact is made without puncturing or spearing the ball. • Increasing run time/insertion counts between cleaning • The open hoop does not trap solder debris

  3. Self Aligning, Great Wipe, and Self Cleaning • The contact hoop floats for hundreds of thousands of low resistance low insertion force test cycles (ball insertions) • Free floating significantly reduces side lateral shear forces that can and do dislodge balls from the package • Oxide removal and self cleaning during contact : • The hoop travels downward through an arc providing rotational hoop wipe (the hoop rim rotates) on the surface of the ball. • The rotation of the rim is a progressive radial orientation to the point of contact with the mating solder ball. • This effect is produced using the on-center axis centerline of the contact pin.

  4. Circumflex Metal Alloy • Gold plating wear issues are eliminated • Solder buildup problems are extensively or entirely eliminated (no stick metal alloy) • Solder debris is not trapped • The open architecture of a hoop does not trap solder • The metal alloy and geometric shape work as a system producing longer mean-times-between-cleaning

  5. Circumflex Contact Geometry • Through the use of simple and effective lines and shapes, the Circumflex is: • A high performance low cost alternative to other contacting technology • An on-center design • A drop in replacement • You can use your existing setup and conversion kit hardware with the Circumflex contactor

  8. Thank You • Circumflex contactors are the result of putting collective imagination to work with more than 77 years of engineering experience that includes a combined knowledge of semiconductor package test and high performance contactor development. • Starting with a good idea, we have developed a better product, i.e., the design of a contact pin that allows long uninterrupted test runs at maximum insertion speeds with the highest yields. • From digital device testing, analog testing, and mixed signal device testing, the business facts are: • Nuwix’s Circumflex contact pin provides a high return on investment as measured by: • Reliability • Long run times between cleaning • Interchangeability with existing hardware • High yields at a low cost • Ease of use
