ISTA (International Safe Transit Association Standards) Sets the standard for optimizing packages that are survivable, sustainable, and successful with ISTA package testing, manufacturers improve products and packages, which be protects their reputations and their bottom lines. Why Package testing requires: The package in which product contains and transit internationally and national region, it should reach safely to the end user […]

The classic ElectroDynamic (ED) vibration system has been used for many years to accelerate vibration fatigue in Accelerated Life Testing (ALT). Shaped random Power Spectral Density excitation (PSDs) were specified to meet specific stress goals, and they could be generated and controlled very precisely. The profile, shown in Figure 1, became a de facto standard

If we classify the materials on basis of their electrical property we can broadly classify them into three main categories namely Conductors, Insulators and Semiconductors. In this blog we will be discussing about semiconductors, doping and the method of doping. Though the exact invention year of semiconductor characteristic of material is not known but one

Physical vapour Deposition (PVD) is a family of processes that is used to deposit layers of atoms or molecules from the vapour phase onto a solid substrate in a vacuum chamber. PVD is characterized by a process in which the material goes from a condensed phase to a vapour phase and then back to a

NDT is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component, or system without causing damage. Non–destructive testing (NDT) is a mechanism used by engineers to detect defects in materials and structures, either during manufacturing or while in service. Typically, the methods used are ultrasonics,

In the world of Defence, testing and analysis play a prominent role. Defence transportation involves high stakes, as it transports highly sensitive and dangerous materials. Testing of a defence transportation vehicle involves in vibration testing, shaker testing, vehicle failures, performance testing and product screening. Electrodynamics, data physics and servo hydraulics are the standard solutions, which

The damage-free dry cleaning method can remove the organic contaminants that stick to the substrates by a photochemical oxidation resolution process. Benefits of UV ozone cleaning method:●Easy removal of organic contaminants on the substrate that could not be removed by ultrasonic cleaning alone.●Removal of the organic solvent used in wet cleaning.●Possibility of removing organic contaminants
Electron microscopy has a diverse range of applications in practice. The ability to view the microscopic structure of a specimen at a higher resolution than what is possible with optical microscopy gives it a distinct role in scientific research and industry applications. Several of these applications are covered in more detail below. Scientific Research :

A mask aligner is a precision machine tool used in the semiconductor manufacturing process to transfer a pattern onto a wafer or substrate; these patterns are micro and Nano in scale. The patterns (structure) are created using a light transfer method, where the pattern (printed on photo mask) to be printed is placed between a

Active thermography is the induction of a heat flow by energetically exciting a test object. This can be done either by applying energy in a pulsed form (pulsed thermography) or in a harmonic modulated way (lock-in thermography). The propagation of the heat flow inside the object directly affects the temporal behaviour of the surface temperature.
