Synthetic Sapphire: Extreme Performer

Sapphire, the single crystal form of alumina (Al2O3), was first synthesized more than a century ago, but the most exciting advances associated with this versatile material are taking place today. Shaped by the dual forces of application demands and technological advances in the fabrication and finishing process, synthetic sapphire is often the material of choice for design engineers dealing with extreme conditions of high temperature, high pressure and harsh chemical environments.

The Basics Of Pressure Regulators

Pressure regulators are found in many common home and industrial applications. For example, pressure regulators are used in gas grills to regulate propane pressure, in home furnaces to regulate natural gas, in medical/dental equipment regulate oxygen and anesthesia gases, in pneumatic automation systems to regulate compressed air, in engines to regulate fuel pressure, and in fuel cells to regulate hydrogen. Although the applications vary considerably, the pressure regulators provide the same function. Pressure regulators reduce a supply pressure to a lower outlet pressure and they maintain this outlet pressure regardless of inlet pressure fluctuations. This reduction in pressure is the key characteristic of pressure regulators; outlet pressure is always at a pressure below the inlet pressure.

Performance Characteristics of Digital Frequency Discriminators

Digital frequency discriminators are key components of instantaneous frequency measurement (IFM) receiver systems as well as many other complex electronic warfare (EW) systems. However, to obtain optimum results it is essential to match DFD performance levels to a specific application. DFDs are integral components of IFM receiver systems; they may also be imbedded into a wide range of military systems such as radar warning receivers (RWRs), electronic countermeasures (ECM) systems, and electronic support measures (ESM) platforms, where they help provide instantaneous frequency measurement capability.

The True Cost of Bearing Lubrication

Today, machine and equipment manufacturers are feeling more pressure than ever to reduce costs without sacrificing machine performance and this balancing act can be difficult to achieve. Original equipment manufacturers (OEMs) often overlook a simple solution that can have a positive, long-term impact on profitability for themselves and their customers: the elimination of bearing lubricant. By eliminating lubrication systems where possible, OEMs can reduce production costs, while at the same time making their equipment more marketable and less expensive to operate for the end users.

How Lean Manufacturing Adds Value to PCB Production

In an earlier paper, we established the importance of Design for Manufacturing (DFM) in today’s PCB manufacturing environment. PCBs designed using those techniques typically experience reduced failure rates, cost less to manufacture, and minimize waste during production.

The Significance of Critical Cleaning for Solar Module Fabrication

With increased governmental commitments to support renewable energy initiatives, winners and losers in solar module fabrication will be determined more quickly and by a variety of factors. One factor will be the elimination of defects to increase yields in the manufacturing process. Critical cleaning of substrates and superstrates is an essential component in achieving an optimal solar module fabrication process which reduces the cost per watt. Depending on the material being cleaned and the cleaning process employed, various Alconox products, including ALCONOX, DETOJET, LIQUINOX, CITRANOX and CITRAJET, have already been selected by major manufacturers as the critical cleaners of choice to reduce or eliminate manufacturing defects in solar module fabrication and are being employed in additional emerging processes.
