Fundamentals of Vector Network Analysis Primer

One of the most common measuring tasks in RF engineering involves analysis of circuits (networks). A network analyzer is an instrument that is designed to handle this job with great precision and efficiency. Circuits that can be analyzed using network analyzers range from simple devices such as filters and amplifiers to complex modules used in communications satellites.

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.

Bearing selection for low-speed applications

Low-speed applications present design challenges for bearings, just as high-speed applications do. (Uneven wear from intermittent motion, torque uniformity and vibration resistance are a few examples.) A new white paper from Kaydon Bearings, an SKF Group company, looks at the type of bearings typically used in low-speed applications and reviews 10 key performance requirements designers should consider when specifying them.

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.

Key Procedures and Aqueous Cleaning Agents for Metal and Electronic Component Cleaning

Effective use of aqueous cleaners for electronics and metals hinges on the orchestration of basic variables of cleaning agents and procedures. The terms precision or critical cleaning apply whenever residue can cause a failure in the performance or function of the surface being cleaned. In general industry this includes electronic component cleaning, and surface preparation of metals prior to coating or bonding. Current practice for critical cleaning includes the use of volatile solvents, corrosive chemicals, and aqueous detergents. In today’ hazard-sensitive workplace, however, many companies are re-examining their use of volatile-solvent and corrosive-chemical cleaners. By using the right aqueous cleaning technologies now, it’ possible to minimize hazards without sacrificing critical cleaning performance. Many aqueous cleaners now offer cleaning performance comparable to - or better than solvent cleaning systems.

Re-Inventing the Rotary Encoder: The No-Compromise IXARC from POSITAL

Designers of motion control or industrial automation systems who need to measure the rotation of shafts or other mechanical components have had two types of rotary encoders to choose from. Encoders based on optical measurement techniques can provide high levels of precision and dynamic response, but are relatively bulky and can be unreliable in damp or dusty conditions. Magnetic encoders are typically more compact and rugged, but until now, have offered lower levels of precision and dynamic response. POSITAL has eliminated the need for compromise by developing a new generation of magnetic absolute and incremental encoders that match the performance of optical shaft-mounted encoders in all but the most demanding applications. The new magnetic IXARC encoders are compact, accurate, fast and tough enough for challenging environmental conditions.
