Advanced Control of 3D Printers through Voxel

The spectacularly astonishing new technology, additive manufacturing or 3-D printing, continues to grow thanks to reducing costs, new processors, and greater research. The price reduction comes mainly from an increase in the availability of and access to the technology to a broader audience. However, it has other things going for it too, such as increasing automation, expanding materials, improving software, and voxel control, all continuing to push the limits of additive manufacturing. According Read more [...]

Advanced PCB Technologies — High Density Interconnect

Engineers often face a peculiar dilemma. On one hand, they need to enhance the functionalities of electronic gadgets they design so that customers have more value for their money, while they are constrained to use a sleek form factor. Not only does this impose a tremendous challenge to cram many components within a highly restricted space, but the challenge extends to maintaining the quality and integrity of the design as well. Designers meet the challenge in different ways. They use subminiature Read more [...]

How mSAP Enhances HDI PCB Capabilities

With 5G technology around the corner, we are looking at the emergence of 5G smartphones. While this requires new manufacturing technologies such as high-density interconnect Printed Circuit Boards (HDI PCB), smartphones need to be less expensive and produced at greater efficiencies. Customers usually covet compact sleek devices. Therefore, manufacturers need to balance function and form so that their products stand out in a crowd in a competitive marketplace. The smartphone market can be a treacherous Read more [...]

How Are Industrial Lasers Cooled?

There are several varieties of industrial lasers. Some lasers, such as fiber lasers, have specific arrangements that enable spreading the heat they generate over a larger surface area. This arrangement gives fiber lasers better cooling characteristics over other media. Other lasers need extra cooling arrangements to remove the heat they generate. For example, ion lasers generate extreme heat when active and need elaborate cooling methods. Other lasers, emitting energy in the microwave and far-infrared Read more [...]

Using the Raspberry Pi to Secure IoT

The popular single board computer, the Raspberry Pi (RBPi), can effectively secure systems that traditional protection mechanisms often cannot. Industrial control system networks and Internet of Things fall under this category. You can use the RBPi2B and later models as an adequate medium for running the various security tools. For this project, you need a Micro SD card of at least 8 GB size, and the bigger it is the better, as you can use the extra space to store a longer log data history, for Read more [...]

Tuning an IoT MEMS Switch

Menlo Microsystems, a startup from GE, is making a MEMS-based switch fit into a broad array of systems related to Internet of Things (IoT). Already incorporated into medical systems of GE, they can tune the chip to act as a relay and power actuator for several types of industrial IoT uses, including using it as an RF switch suitable for mobile systems. Menlo first described their electrostatic switch in 2014. They have designed it with unique metal alloys deposited on a substrate of glass. The arrangement Read more [...]

How are Transformers Protected in the Field?

For maintaining a power grid in continuous working order, power transformers play a critical part. As repair and/or replacement of components in a power grid typically has a long lead time, protection from faults has to limit the damage to a faulted transformer. Moreover, transformer faults need quick prevention, and certain protection features identify operating conditions that could cause a failure of the transformer. This includes over-excitation protection and temperature-based protection. Classification Read more [...]

Butterfly IQ – Smartphone Connected Ultrasound Scanner

Traditional ultrasound scanners are rather expensive, and rarely do people own one to use at home. However, that may be about to change, as Butterfly IQ has now obtained FDA clearance for a portable ultrasound scanner that anyone can use by connecting to their smartphones. Connecticut-based Butterfly IQ has made an innovative ultrasound scanner that uses a semiconductor chip for generating the ultrasonic signals, rather than the piezoelectric crystal transducers that traditional ultrasound machines Read more [...]

Lead-Free Reflow for High-Layer-Count PCBs

High-layer-count multilayer printed circuit boards (PCBs) present one of the most difficult cases for adaptation to the lead-free reflow assembly process. Often, these boards have through-hole and hand-soldered components, along with the requirement for two or more rework cycles. The slower wetting and higher reflow temperatures of lead-free solders place an enormous strain on the laminates and copper-plated hole barrels of the vias, with resulting loss of reliability. Restrictions on Hazardous Read more [...]

How Counterfeit Electronic Parts and Components Affect Businesses

Although counterfeiting has been an age-old industry, it is only recently that the impact of counterfeit electronic parts and components has come to be highlighted. The public is slowly gaining the awareness of the implications and risks such counterfeited electronics bring to trusting users. It is difficult for manufacturers to trace the origin of the counterfeited parts compared to the traceability present for the authentic components. It is possible these are older, but legitimate versions Read more [...]
