Managing Thermal Energy with a Finely-Tuned Adhesive


Heat, vibration, moisture, and dust can all wreak havoc in electrical systems. With the miniaturization of components, heat or thermal management becomes an even more critical factor in the design process. Managing heat in processing, heat dissipation, and thermal expansion and contraction ...

Progressive Cavity Pumps Enable Vital Precision and Repeatability


Up until roughly five years ago, operators of manual and automated dispensing lines had little ability to achieve highly-accurate, consistent application of adhesives, epoxies and other fluids. This was especially difficult for small depositions, when working with viscous materials ...

Ultrasonic Piezo Transducers for Smart Sensors


Piezoelectric transducers are based on electro-ceramic materials that convert mechanical power into electrical power and vice versa. There are two effects. First, when a force is applied, an electric charge is generated (direct piezo effect). Then, when an electric field is applied ...

A Practical Guide to Managing Material Cost


Many years ago, I ran a high-mix, low- to mid-volume EMS business. Like everyone else, surprise shortages were driving the million dollar SMT lines to screeching halts. Often the familiar sound of "cha-ching" would stop, and everyone scrambled to find the part that was supposed to be ...

Combining Thin-Layer and PCB Technology in Microelectronics


The boundaries between thin-layer and printed circuit technology in microelectronics are becoming increasingly blurred. At the same time, the demand for thin-layer circuits and miniaturized components continues to grow. Cicor, an industrial provider of advanced microelectronics, uses ...

Embedded Components: The New Frontier for PCBs


Less is more. At least in the size of the printed circuits for most devices we make today. As the race to make things smaller continues, manufacturers have begun to build previously surface-mounted components into the layers of a PCB. Over the last few years, embedding components in ...

Faster Product Cycles: Can Your Supply Chain Keep Up?


There is a popular adage when it comes to business: cheap, fast, or good — pick two. The electronics market is demanding ever-faster development, greater performance and cost-efficiency from every product. To better deliver in all three of these areas, solid collaboration and commitment ...

Mission-Critical Applications: Qual-Pro Advanced 3D Inspection


America's space program is moving ahead on several fronts in an effort to rid NASA of its dependence on Russian Soyez spacecraft. An important part of this program is the Boeing Starliner, a spacecraft that will ultimately do the kinds of jobs that had been handled by the now-retired ...

New Jetting Technology for Fluid Dispensing


In jetting, fluid is rapidly ejected through a nozzle and uses momentum to break free in discrete droplets. Jetting has evolved to become a standard production process in the industry, and now accommodates a wide variety of fluids and applications. Everything from more intricate, emerging ...

Predicting Assembly Yields by Viscosity Measurement


According to dozens of published surface-mount process studies, up to 80 percent of defects occur when solder paste is stencil-printed onto a bare board. Many of the problems can be traced back to the interaction of the process equipment and the flow quality of the solder paste. In ...

Saki Celebrates Over Two Decades of Technology and Expansion


"When we began, AOI was a luxury", says Jodie Akiyama, CEO of Saki. "Now it's a necessity." In 1994, Sakie (Jodie) and Yoshihiro Akiyama founded Saki Corporation in Japan. At the time, the electronics inspection market was dominated by large corporations that offered AOI technology, but ...

Sharpening the Competitive Edge: Lenze Americas and Samsung


In the early 1990s, PCB manufacturing floated overseas, lured by cheap labor and free trade. Now, many plants in the U.S. using the same equipment and paying more for labor, produce little by comparison. The industry in the U.S. consists mainly of those PCB assemblies that are not ...

How Clean Is Clean Enough for Reliability?


Dirt and residues trapped under bottom circuit terminations can affect performance due to shorter distances between conductors, higher pin out devices in smaller footprints, higher electrical field densities, and various environmental factors. No universal test method can ensure proper ...

Reflow in Today's High-Mix/High-Volume Production Environment


Many printed-circuit-board (PCB) production lines working in surface-mount-technology (SMT) markets in the US and Europe can be described as high-mix, low-to-medium-volume lines. Many of these lines experience more downtime than production time, creating a serious challenge: how to ...

Reflow Soldering: With or Without Vacuum?


Vacuum is an emptiness that can be fulfilling, especially for electronics production and reflow soldering. It was when Galileo Galilei (1564-1641) posed the question of the existence of absolute emptiness (from the Roman latitudinus vacuus) that the concept was first brought from the ...

Tester Aims for Zero Defects When Manufacturing PCBs


Zero defects for a manufacturer means never delivering a defective product to a customer. Manufacturers of printed circuit boards (PCBs) are doing absolutely everything in their power to make this happen — knowing full well that they cannot possibly achieve 100 percent zero defects ...
