This paper investigates the effect substrate preparation has on epoxy mold compound (EMC) adhesion to bare copper leads. There have been four basic strategies employed to characterize and subsequently improve adhesion between the EMC and copper: 1. Choosing a particular copper alloy, i.e. varying alloy effects in copper to improve oxidation control and thus adhesion. 2. Modifying the mold compo...

Polymers are materials widely used in biomedical science because of their biocompatibility, and good mechanical properties (which, in some cases, are similar to those of human tissues); however, these materials are, in general, chemically and biologically inert. Surface characteristics, such as topography (at the macro-, micro, and nano-scale), surface chemistry, surface energy, charge, or wett...

The purpose of the present study is to clarify effect surface texturing on lubrication characteristics a sliding under reciprocating motion and develop design guidelines for in order obtain lower friction. To achieve this purpose, with dimple-shaped during are numerically analyzed by solving Reynolds equation. effects compared those no various operating conditions as determined from speed, visc...

Numerical analysis has been performed solving Reynolds equation using finite element method evaluate texturing．The major results...

Surface Plasmon Polaritons (SPPs) have been known since the late 1950s with the work of Richie [1]. Today most research with these surface waves is aimed at production of subwavelength components in an attempt to merge the subjects of electronics and photonics on a nanometer scale. However, the features produced by SPPs could have uses in direct engineering applications due to their surface tex...

Nanoscale texturing has been studied for various applications, but most of the methods used to make these nanostructures are expensive and not easily scalable. Some of these methods require etching steps or high-temperature processes, which limit the processes to certain materials, such as silicon. In this study, we report a non-etching nanoscale texturing technique that allows for controlled o...

The potential of ultrafast lasers (pico- to femtosecond) in orthopedics-related procedures has been studied extensively for clinical adoption. As compared conventional laser systems with continuous wave or longer pulse, provide advantages such as higher precision and minimal collateral thermal damages. Translation surgical applications the clinic restrained by limitations material removal rate ...
