Rapid development in the design of electronic packages for modern high-speed computers has led to the demand for effective methods of chip cooling. The primary concerns in thermal management applications are high thermal conductivity, large specific surface area and low weight. Graphite foams which possess predominantly spherical pores with smaller openings between the cells constitute a novel highly-conductive...
With the relentless trend of increasing power and decreasing dimensions, thermal management of electronic packages is becoming a critical issue. Existing cooling techniques are fast becoming inadequate for the powerful electronic components expected in the near future. Researchers all over the world have been experimenting with advanced cooling techniques such as spray and impingement cooling using...
With the proliferation of mobile electronics in everyday life, the ability of electronic packages to sustain impact loading under drop conditions has become a paramount reliability concern. Since solder joints, which serve as mechanical and electrical interconnects in a package, are particularly prone to failure during a drop, the fracture behavior of solders at high strain rates is a critically important...
Silicon wafers and dies are single crystal in semiconductor applications which must withstand high stresses within electronic packages. The apparent mechanical strength of single crystal Si depends on process induced defects. Mechanical bending tests are the simplest way to obtain the strength of Si dies and wafers and have been used for many years throughout the industry. Some of the bending tests,...
