How to Properly Calculate Reflow Temperature Gradients
Publication Date: 2/2/2017


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
Publication Date: 2/2/2017


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
Publication Date: 2/6/2017


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
Publication Date: 2/6/2017


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
Publication Date: 2/6/2017

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

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
Publication Date: 2/2/2017


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
Publication Date: 2/2/2017


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
Publication Date: 2/6/2017


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
Publication Date: 11/29/2016


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
Publication Date: 11/29/2016


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
Publication Date: 11/29/2016


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
Publication Date: 11/29/2016


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 ...
Choosing the Right Lighting for Machine Vision Applications
Publication Date: 2/1/2016


Machine vision systems create images by analyzing the reflected light from an object; not the object itself. A good image is the result of proper focus and illumination. Images with poor contrast and uneven illumination require much more effort from the imaging computer, which increases ...
From Asset-centric Management to Service-centric Relationships
Publication Date: 2/1/2016


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
Publication Date: 2/1/2016

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, ...
