Thermal design in the consumer electronics business is about dealing with two difficult challenges: The first is to fulfill, and if possible surpass, customer expectations. The second is to do this in ever shortening design cycles. After a main initial use of flat displays as computer monitors, larger flat display screens are now emerging for video purposes: the Flat TV. … [Read more...]
Power Density Challenges Of Next Generation Telecommunication Networks
Despite the current downturn in the telecommunications industry, data transfer (i.e. network traffic) is continuing to grow at a 100% rate [1]. It is already projected that network traffic demand will reach tens of Tb/s in a couple of years from now (see predicted traffic demands from telecommunications analysts Ryan, Hankin & Kent, Figure 1). At the same time, network … [Read more...]
Packaging And Temperature Control Considerations For Planar Waveguide Circuits
Optical Networking The all-optical network has been emerging as a solution to provide higher bandwidth, lower cost systems for handling high capacity network traffic. Due to the inherent limits of copper wire and the high cost-per-bit of electrical systems, service providers will replace electrical components with fiber optic counterparts wherever possible as the cost of the … [Read more...]
Optical Measurement Of Flip-Chip Package Warpage And Its Effect On Thermal Interfaces
Warpage of FC-PBGA Packages Flip chip technology has emerged as an important chip-level package solution to meet the ever-increasing demand of high I/O requirements. The flip chip technology was implemented originally for a multi-layer ceramic substrate. In the ceramic flip chip package, a shear strain in each bump, produced by the mismatch of the coefficient of thermal … [Read more...]
Glass: A Group Of Familiar Materials With Varying Properties
The knowledge to manufacture glass products is already 4500 - 5000 years old, and glass in its different compounds is one of the most commonly used man-made materials. The material technical definition of glass is loose, but, typically, inorganic products manufactured by fusing and then solidifying without crystallizing can be categorized as glasses. In the electronics industry … [Read more...]
