µHPC/GA Contactors Mechanical Performance
|
- The Torlon 5530
contactor body provides device alignment, while offering superior wear
and abrasion resistance, and a low coefficient of thermal expansion.
The tapered wall of the guideplate provides initial alignment into the contactor. When the DUT reaches the floor of the pocket, chamfered contact element holes provide the next stage of alignment. 
The contact elements provide the final stage of DUT alignment. The DUT, now fully aligned to the contactor, pushes the contact elements into the SMM, which provides compliance and makes solderless electrical contact to the performance board. 
When crown-top contact elements are used, the ridges tapering down from the points of the crown to the center of the element provide the necessary final alignment to the contactor.
- The contact elements
are made of beryllium copper with military-grade, hard-gold plating
to assure long life, as well as excellent electrical performance.
- The SMM provides
the compliance, resiliency and durability that ensures good contact
to both the DUT and the performance board.
- The sharp edges
of the contact elements ensure oxide penetration and good electrical
contact. Sharp edges, by their nature, do not accumulate solder. The
circular, or radial, contact spreads the force over a large area of
the solder ball, resulting in a light contact mark.
- ECT µHPC/GA contactors are designed to be completely rebuildable. The wear items can be replaced to restore the contactor to like-new performance.
