From Asset-centric Management to Service-centric Relationships


As technology has advanced, consumers have grown to expect more. Companies are pushed to create the most powerful, eye-catching smart device; of better quality than competitors, and at a lower price to the customer. In this competitive market, manufacturers must maximize output while ...

Improving Traditional Test Methods

Process inspections, including solder paste inspection (SPI), automated optical inspection (AOI), and X-ray, are able to detect most assembly errors — but others may lurk under the surface. SPI detects if solder paste is missing on certain pads, AOI is capable of identifying missing, misaligned, ...

Leading the Way…With Test and Measurement Solutions


Renting test equipment can result in numerous benefits for a company, including saving in capital expenses by not having to buy the test equipment and not having to store the equipment when it is not being used, or having to upgrade equipment that becomes obsolete with age. Renting ...

Piezo Mechanisms in Optics and Laser Technology


The delivery of a laser beam requires precise motion of optical components. Piezo mechanisms provide just this. Piezoelectric systems are currently the gold standard of motion control, because of their speed and precision. Laser systems engineers have a large toolbox of options at their ...

Saving Valuable Time in SMT and Test Programming


It can take many days for a team to prepare a line for production. First, information is gathered. This includes the details of each placement, test and inspection requirement. The data are often collected in a mass of different formats, both digital and physical, as a designer tries ...

The Evolution of Cleaning Methods in PCB Rework


The rework process has long consisted of three steps: removal of the inoperative component, cleaning of residual solder from the ball grid assembly (BGA) pads which held the component in place, and replacement with a new component to create a viable, working PCB. The first and third ...

DC/DC Converters: It's Not Your Father's Input Voltage Anymore!


Solar, wind turbines, and AC inputs for high-power industrial use are all part of today's design mainstream. This includes 480VAC that can be converted to approximately 680VDC, which is closely tied to great technical leaps in the battery industry. Improved power and reliability are ...

Improving Cable Quality and Reliability — Resistance Measurement to Within 1mΩ


Precision low-value resistance measurements become necessary when testing cables intended to carry significant current. This is of prime importance in high-reliability applications used by the military, medical field, aerospace, and other areas where a life may depend on the accuracy ...

Robust Interconnect Solutions for Reliability


The quality and reliability of an interconnect directly influence system performance and reliability. The impact of an interconnect is often appreciated only when poorly manufactured or incorrectly specified connectors fail, erode system performance, or bring the system to a complete ...

Solderability and Tinning: Does the Industry Know the Difference?


A particular dilemma facing the industry today stems from the difference in purpose of solderability and tinning services. While NJMET has had the privilege of providing these services to the aerospace, military and medical fields, often, purchasing and engineering personnel confuse ...

Solving Power Supply Integration Issues


Design engineers face many challenges when selecting and integrating power supplies into equipment. Most designers search for and choose a supply based solely on its published specifications, believing they have selected the right product for their application. Only after receiving ...

Tiny Components Find Homes in Smaller Circuits


Electronic components are becoming smaller and more energy efficient. These trends are apparent in analog, digital, optical, and hybrid components in many different markets and are enabling the design and development of compact, low-power electronic products for a wide range of users ...

Understanding Video Latency


In most cases, users want latency — the time it takes for a single frame of video to go from a camera to a display — to be as short as possible. A delay between what is seen on a display and what happens can be frustrating and problematic in many situations, such as a machine ...

Counterfeiting: The Rising Threat to Electronics Manufacturers


Serialization technology provides a means by which products can be uniquely identified with a serial number at the unit item level, as opposed to lot or batch levels. The individual item, such as a circuit board, battery, or other component, is assigned a unique serial number embedded ...

Improved Materials and Production Yield Robust Passive Components


New materials and production processes as well as changes in worst-case scenarios are closing the gap between passive component robustness and component stress resistance. Even the smallest irregularities in either of these component aspects will often result in component failures and ...

Sailing is Back in Fashion-Even on the Road!


The proportion of electronics employed in commercial vehicles continues to rise and is expected to grow by 50 percent in 2016. Parallel to this trend is a growing demand for electronic components that are safe, reliable, and energy efficient. More automotive manufacturers are attempting ...

Testing the Quality of Printed Circuit Boards


Printed-circuit boards (PCBs) can be assembled in many different ways, by hand and machine, and can be characterized in almost as many ways, using everything from flying probers to optical measurement methods. Today's PCB measurement solutions can provide combinations of extreme accuracy ...

Testing the Trends in Electronic Measurements


The market for electrical test equipment is undoubtedly growing but, above all, going through major changes. The continued demand for new products in many different industries, combined with a constant demand for total quality of products, has shifted testing away from production and ...

The New Micro in Micro-Dispensing


The term "micro-dispensing" can be confusing, since micro-dispensed circuit features have typically been more on the order of millimeters or just under a millimeter in size. The term "micro" typically refers to volume, so that a microliter or less was an accurate expression for the ...

3D Automated Inspection Uses High-Fidelity Color Imaging


When inspecting assembled printed-circuit boards (PCBs), there has never been a substitute for the human eye. This is due to the fact that human judgment, regarding the integrity of solder joints, is always superior to the judgment of a machine. A skilled engineer or technician knowing ...
