Laser Wire Stripping — Focused on the Science of Interconnects
Adrian Thomas, Regional Sales Manager, Laser Wire Solutions Ltd.
Laser wire stripping was developed to mitigate the risk of damaging delicate wire conductors that is always present when using traditional mechanical wire stripping tools. First developed by NASA in the 1970s, and used for the space program, laser wire stripping allowed the shuttles ...
Reducing the Expense of Servicing Diaphragm Dispensing Valves
By Can La, Product Manager, Techcon Systems
An exponential increase in the availability and use of two-part epoxy adhesives is providing valuable benefits for a growing number of manufacturing applications. Often enabling significantly faster and more dependable bonding than conventional adhesives, two-part adhesives are able to ...
Reliable Soldering for Medical Equipment
By Yusaku Kono, Marketing Director, Japan Unix Co., Ltd.
Medical devices require exceedingly high quality and reliability due to their role in safeguarding human lives. Such devices are designed from specialty components and materials that are not typically seen in consumer electronics. Soldering precision components, which may be extremely ...
Switch On and Get Started with Equipment from Rehm
By Anna-Katharina Peuker, Rehm Thermal Systems GmbH
Blaubeuren-Seissen, Germany — The electronics industry is constantly facing new challenges in the processing of components — from handling the smallest parts to achieving the highest standards in void-free solder joints, and increasing quality through resistant conformal coatings ...
Taking Charge of ESD Caused by Tapes and Labels
By Dave Genest, Marketing Communications Manager, Polyonics, Inc.
Electrostatic discharge (ESD) is present in everyday life, and its effects range from mildly unpleasant to extremely dangerous. From taking static-charged clothes out of the dryer to touching a lamp after shuffling your feet across a rug in dry weather, to storm clouds creating lightning ...
Ultrasonic Welding Meets Needs of Complex Automotive Electronics
By Melissa Alleman, Vice President, Sonobond Ultrasonics
Sonobond Ultrasonic's metal welding technology has been developing alongside the growing number of increasingly complex electronic components, especially those in the automotive industry. The company offers wire-to-terminal welders that produce single point ground terminals, and can ...
When Lightning Strikes — Keeping Aircraft Flying
By Jason Evans and Joseph Kane, MK Test Systems, Ltd.
If you travel regularly by air, then it is quite likely that while flying through a thunderstorm your plane was struck by lightning. You probably weren't aware of it, and that is the way it should be. A lightning strike is a safety-critical event and happens so frequently that it can ...
A Practical Guide to Managing Material Cost
By Ben Khoshnood, President, Inovaxe Corp.
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
By Ursula Gore, Cicor Americas, Inc.
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
By Walter Gueili, Seica S.p.A., Strambino, Italy
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 ...
Faster Product Cycles: Can Your Supply Chain Keep Up?
By Stefan Merlau, Global Product Manager SMT, Heraeus Electronics
There is a popular adage when it comes to business: cheap, fast, or good — pick two. The electronics market is demanding ever-faster development, greater performance and cost-efficiency from every product. To better deliver in all three of these areas, solid collaboration and commitment ...
Mission-Critical Applications: Qual-Pro Advanced 3D Inspection
By Steve Wongsonvanee, Pemtron Technology and Michael McCallion, Qual-Pro
America's space program is moving ahead on several fronts in an effort to rid NASA of its dependence on Russian Soyez spacecraft. An important part of this program is the Boeing Starliner, a spacecraft that will ultimately do the kinds of jobs that had been handled by the now-retired ...
New Jetting Technology for Fluid Dispensing
By Garrett Wong and Roberta Foster-Smith, Nordson ASYMTEK
In jetting, fluid is rapidly ejected through a nozzle and uses momentum to break free in discrete droplets. Jetting has evolved to become a standard production process in the industry, and now accommodates a wide variety of fluids and applications. Everything from more intricate, emerging ...
Predicting Assembly Yields by Viscosity Measurement
Mitch Holtzer, Global Director of Customer Technical Support, Alpha Assembly Solutions
According to dozens of published surface-mount process studies, up to 80 percent of defects occur when solder paste is stencil-printed onto a bare board. Many of the problems can be traced back to the interaction of the process equipment and the flow quality of the solder paste. In ...
Saki Celebrates Over Two Decades of Technology and Expansion
By Michael Skinner, Assistant Editor
"When we began, AOI was a luxury", says Jodie Akiyama, CEO of Saki. "Now it's a necessity." In 1994, Sakie (Jodie) and Yoshihiro Akiyama founded Saki Corporation in Japan. At the time, the electronics inspection market was dominated by large corporations that offered AOI technology, but ...
Sharpening the Competitive Edge: Lenze Americas and Samsung
By Don Lockard, Yankee Soldering,Vince Parente and Nick Siciliano, Lenze Americas
In the early 1990s, PCB manufacturing floated overseas, lured by cheap labor and free trade. Now, many plants in the U.S. using the same equipment and paying more for labor, produce little by comparison. The industry in the U.S. consists mainly of those PCB assemblies that are not ...
Choosing the Right Lighting for Machine Vision Applications
By John Lewis, Global Content Marketing Manager — Vision, Cognex Corporation
