Funding New Solder Purchases by Recycling Metals Waste


It is quite a leap for an electronics manufacturer to go from paying to have its metals waste hauled and disposed of to getting paid to have its solder dross and metals waste carried away. That is exactly what happened to Nashville, Tennessee-based Link Electric and Safety Control ...

More Than a Decade After RoHS: The Landscape of Lead-Free Solder


The implementation of RoHS was the end of "easy" soldering for most PCB assemblies. Lead-bearing solders, such as the well-established eutectic Sn63Pb37 had been well-defined and optimized for soldering. Lead-based solders wet very well, even in applications with occasional borderline ...

Putting "Design" Back into Design for Test


Typically, PCB production and design for test (DFT) engineers work in different silos, often with little communication between them, making testing costly and less effective. This especially impacts industries where reliability and quality routinely protect human lives, such as in the ...

Thermosyphons: Design Theory


Managing large amounts of heat in any application is always a challenge. Heat transfer mechanisms generally rely on solid metal to conduct thermal energy away from its source. An alternative method, a thermosyphon, is a highly effective heat transfer device that uses the phenomenon ...

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 ...
