DES PLAINES, IL — Kester will highlight SE-CURE UT-10 TIM in booth 8802 at Semicon West.

The lead-free, SMT-compatible, high-performance thermal interface material consists of a paste containing both fusible and non-fusible metals in a 100%-solids, thermosetting polymer matrix. Can be dispensed or stencil-printed and is processable on standard lead-free SMT reflow profiles. Can be used for attachment of power die to lead frames or ceramic or organic substrates. The fusible alloy is Sn96.5Ag3.0Cu0.5.

Features an advanced three-component composite system that leverages polymer and metals technology. The material costs less than silver-filled adhesives.

Reportedly provides higher performance than Ag-filled adhesives at lower material and overall process costs. Controlled-collapse bond line ensures repeatable assembly characteristics and thermal performance. In applications where over-molding is performed, it eliminates problems associated with solder squirting. The polymer component is compatible with epoxy-based over-molding chemistry.

The Nikon ECLIPSE LV series includes the ECLIPSE LV150, LV150A (with automated nosepiece) and the ECLIPSE LV100D (episcopic/diascopic illumination) microscopes. Said to address the need for precise microscopy measuring solutions to keep up with higher performance demands in the semiconductor and medical device markets, the rapid development of new materials and the inspection requirements of components with widely varying dimensions.

The modular design allows versatility and flexibility that enables it to cover a variety of applications, from development and quality control to manufacturing inspection. Reportedly provide superb performance when inspecting semiconductors, flat panel displays, packages, electronics substrates, materials, medical devices and other samples. Can accommodate sample heights from 47 to 82mm by inserting a column riser between the main body and arm of the microscope. This feature is useful for viewing the surface of precision molds, optical materials and other thick samples.

Accepts industry-supplied stages handle samples up to 116.5 mm, for observation of fiber ends and other tools. Features a range of industrial stages and accessories, all are durable with a new triple plate design.

A variety of observation methods are available, including: first order compensator, UV polarizing and epi-fluorescence -- in addition to brightfield, darkfield, DIC and simple polarizing. Have a high- intensity, low-power consumption white halogen light source, and an adjustable high intensity mercury fiber light source.
