Good Chemistry: Studying PCB Cleaning Processes
By Patrick Duchi, Inventec Performance Chemicals
The ability to effectively clean a PCB has been complicated by the ban of CFCs and HCFCs, which offer outstanding solvency power and low surface tension to dissolve and remove contaminants within minutes, leaving electronics clean and dry. Meanwhile, the exponential growth of miniaturized ...
How to Properly Calculate Reflow Temperature Gradients
By Vitor Barros, General Manager, KIC Europe
The theory is simple: Process electronic assemblies in spec every time and the result is a quality product. In practice, however, this is much more difficult for numerous reasons, including normal and abnormal process variations, human error, and many other factors.
In and Out of Flux: Choosing the Right Flux for Selective Soldering
By Eddie Groves, Selective Soldering Academy, and Jonathan Wol, Pillarhouse USA
The flux chosen for the selective soldering process has a direct and significant impact on solder joint quality, long-term reliability and overall soldering performance. Fluxes essentially fall into three basic categories: low-solids/no-clean fluxes, rosin fluxes (full/high-solids rosins ...
INGUN and Goepel Partner for High-Speed Digital Testing
By the Staff of Ingun USA
Thorough signal integrity tests are required for high data rates and high-frequency applications. In today's world of complex electronic designs, it is becoming critically important to fully characterize electrical connections and transmission lines, going far beyond simple "go-no-go ...
Innovation Takes More Than Good Tools
By Angela Greenidge, EDSYN, Inc.
Using the right tool is essential to getting a job done right. But, what determines the "right tool" for the job? When asked, one individual replied with the question, "The right tool for what?" Another stated, "The wrong tool will get the job done wrong!" These pragmatic responses ring true. Essentially ...
JTAG Pushes Boundary Scan Envelope
Eindhoven, the Netherlands — JTAG Technologies is premiering several new hardware products for PCB testing and in-system device programming, and is also introducing its collaborative product with Altium — JTAG Maps.
Making a Splash with Water-Resistant Digital Devices
By Doug Clark
The trend in consumer electronics has always been to make devices faster, smarter, and with ever-expanding capabilities. But, waterproofing has become a new focus of global electronics manufacturers and many brands are rushing to include this benefit to ensure they are not left behind ...
Optimizing Multi-Board System Design
By Craig Armenti, PCB Marketing Engineer, Mentor Graphics
Designing electronic systems has become measurably more complex during the past decade. Many of the products that we use today are, in fact, complex interconnected systems. Simply put, a "system" is a hierarchical integration of sub-components that are combined to create a product. ...
Precision Vibration Isolation in the Cleanroom
By Jim McMahon
For decades, pneumatic air tables have been the workhorse for reducing vibrations in cleanrooms for manufacturing and research, where critical micro-engineering instrumentation is employed. But just as technology has steadily pushed the boundaries into nano-applications in microelectronics ...
The Impact of LV 214-4: German Automotive OEM Connector Test Spec
By Rob Boyd, Senior Production Manager, Schleuniger
A primary goal of every manufacturer is ensuring that they create quality products. Standards and specifications from various organizations provide guidelines by which manufacturers can measure different areas of quality, while also providing the end user with the assurance that they are purchasing ...
Post-Reflow Acoustic Micro Imaging
By Tom Adams, Consultant, Sonoscan
Before plastic-packaged ICs and other component types are mounted on a board, they are frequently inspected by a variety of methods including acoustic micro imaging tools to ensure quality. Ultrasound is able to reveal structural defects in ICs, flip chips, ceramic chip capacitors and ...
Reducing the PCB Bone Pile: Optimizing Test Strategy
By Peter van den Eijnden, Managing Director, JTAG Technologies
Having worked within an established company in the world of PCB assembly testing for many years we still come across companies (OEMs) who will tell us, "We don't need to test, because we demand that the contract manufacturer (CM) only send us 100 percent working boards." But, demanding ...
Using Conformal Coating to Protect Sensitive Electronics
By Manuel Schwarzenbolz, Product Manager, Rehm Thermal Systems
To give electronic devices the longest possible operational lifespan, conformal coating was developed to protect components, and ensures that today's electronics function properly in a variety of harsh conditions. Despite the unrelenting miniaturization of components, a suitable coating ...
Using Self-Configuring Sensors for Machine Condition Monitoring
By Will Meenan, Kaman Precision Products
Condition monitoring that requires sensors is quickly becoming an imperative throughout many industries. New digital signal conditioner technology is available that simplifies the use of eddy current (inductive) displacement sensors for high-precision and high-reliability applications ...
Autonomous Driving: Getting It Right
By Tamara Drexler, Rutronik Elektronische Bauelemente GmbH
The key to securing the acceptance of autonomous vehicles lies in guaranteeing their safety. This includes data security, protecting against attacks and against the disclosure of confidential data, such as motion profiles, and ensuring the quality of data stored in the vehicle. Along ...
Developing an Integrated 3D Inspection Solution
By Mary Kim, Marketing Manager, Koh Young
Today's inspection systems have moved far beyond simple, isolated machines that passively monitor PCBs on their way down the production line. Broad market demands for accuracy, quality and automation have pushed inspection providers to deliver solutions that make up integrated inspection ...
Efficient Connectors Enable Shrinking Medical Devices
By Ed Garstkiewicz, Industry Segment Manager, HARTING North America
The need to minimize healthcare costs is creating greater demand for medical electronics equipment that, among other things, improves and expands patient diagnostics inside and outside healthcare facilities. For example, portable medical instruments such as glucose meters, blood pressure ...
Industrial USB Connectors: Universal at Last?
By Nicolas Prou, Product Manager, USB Connectors, Würth Elektronik eiSos
Originally designed for the consumer market, the universal serial bus (USB) rapidly became a standard in the field. Now, with the launch of USB 3.1, the technology is ready for industrial applications. USB completely replaced many other ports on computers in consumer markets, thereby ...
Keeping People in Mind: Safe, Reliable and Ergonomic HMI Design
By Joe Torzillo, Vice President Sales, HMI Components, EAO Corp.
Human Machine Interface (HMI) encompasses all the elements of interaction between a person and a machine. The task of the HMI designer is to create safe, reliable and ergonomic systems that allow the operator to monitor and control various machines and processes as efficiently as possible ...
Risky Business: Keeping the Smart Factory Secure
By Hubertus Grobbel, Security Products Manager, Swissbit AG
IIoT (Industrial Internet of Things) and smart factories rely on sensors, actuators and systems that are networked and communicate with each other, but how can that data be safeguarded against espionage and sabotage? Smart and highly-flexible SD cards with integrated security for system ...
