Creating an Efficient Convection Soldering System with Vacuum and Pyrolysis
By Dr. Hans Bell, Jochen Burkhardt, Marcel Kneer, and Paul Wild, Rehm Thermal Systems
Demand for power electronics systems, such as IGBTs (insulated-gate bipolar transistors), is on the rise. The booming markets of e-mobility, LED-based lighting, photovoltaics, and wind power systems require fast, efficient, high-power electrical switching.
Creating the Best User Experience for Wire Processing Equipment
By Patrick Moroney, Product Marketing Manager, Komax Wire
As consumers, we pay attention to the look and feel of our smartphones, car interiors, kitchen appliances, keyboards, and apps. In fact, when we encounter substandard design, we notice it right away. We demand and expect a good user experience from the products we use in our personal ...
EMI Shielding: Improving Sidewall Coverage with Tilt Spray Coating
By Mike Szuch, Akira Morita and Garret Wong, Nordson ASYMTEK; Mike Sakaguchi and Hiroaki Umeda, Tatsuta Electric Wire & Cable Company Limited
EMI shielding has always been an important component of RF devices, but the demands of today's Bluetooth, Wi-Fi, 3G, LTE, wearable, and IoT devices have created a special set of hurdles for the manufacturing engineer. These devices rely on different radio frequencies that can interfere ...
Enhanced Manufacturing Services 4.0: Philosophy and DfT 4.0
By Chrisophe Lotz, President and CEO, Aster Technologies
Industry 4.0 is the widely-used name for the current trend of automation and data exchange in manufacturing. The concept is being applied by many in order to create the smart factory. Within the modular elements of smart factories, cyber-physical systems monitor physical processes, ...
QA on the Fly - Fast, Accurate AOI and XYZ Measurement
By Dr. Subodh Kulkarni, President and CEO, CyberOptics Corporation
In general, you can have very fast sensors that are not so accurate, or very accurate sensors that are not so fast. Having both at the same time has been critical to CyberOptics' development.
The Economics of Die Attach Voiding in LED Assemblies
By Griffin Lemaster, Dr. Bill Cardoso and Dr. Glen Thomas, Creative Electron, Inc.
Improvements in high-brightness LED technologies are making these devices useful for general illumination. But, before LEDs can completely replace outmoded light sources, their thermal management schemes need to be further developed to ensure consistent color quality and long operational ...
A Winning Scenario for Cleaned Circuit Assemblies
By Mike Konrad, Aqueous Technologies Corporation
Much can be learned from 28 years involvement in the electronics assembly cleaning industry. This almost three-decade period can be separated into three distinct periods. Prior to 1989, virtually all assemblies were cleaned after soldering. During the period from 1989 through 2005, ...
Defining Requirements For Kelvin Testers
By Gerhard Gschwendtberger Business Unit Manager Contactors, Multitest Elektronische Systeme GmbH, Rosenheim, Germany
Kelvin contactors can provide precise resistance measurements in high-volume production environments. Kelvin test is not new, but still benefits analog and mixed-signal circuit production test through accurate resistance measurements and compensation of unwanted parasitic circuit elements ...
Dispensing Systems Can Pay for Themselves
By David Upton, Director of Marketing, FRC-Fluid Research Corp.
Adhesives and sealants based on epoxy, silicone, and urethane typically require precise formulations to be effective, and establishing the proper mix and dispensing process for those materials is critical to success. In fact, suppliers of those materials routinely sell their formulations ...
Vacating Voids in QFN Packages
By Raimund Faber, General Manager Sales & Marketing, SMT Wertheim, Wertheim, Germany
Surface-mount components rely on tiny housings such as QFN packages for their electrical and mechanical health and well-being. QFN, or quad-flat-no-lead housings, are leadless packages used throughout applications calling for surface-mount-technology (SMT) devices. With electrical contacts ...
Meter Mix Dispensing Reduces Production Time and Cost
By David Upton, Director of Marketing, FRC-Fluid Research Corporation, Tustin, CA
Precisely applying today's epoxy, silicone and urethane-based adhesives and sealants require the proper meter mix and dispensing process. Material manufacturers are constantly selling their formulations based on the benefits that they provide, and rely on their customers to properly ...
Process Improvements in Fluid Dispensing
By Dan Ashley, Nordson ASYMTEK, Carlsbad, CA
Jetting is the fluid dispensing process where fluid is rapidly ejected through a nozzle and uses the fluid momentum to break free from the nozzle. Jet dispensing has been available in the electronics manufacturing industry since 1993 when jetting technology was first introduced by Nordson ...
The Reality of Design for Assembly
By Noah Fenley, ACD, Richardson, TX
Understanding the concept behind design for assembly (DFA) is the key to a successful assembly. Unfortunately, this often includes an ongoing struggle to balance assembly, fabrication and layout ? these elements must work together in order for the process to run smoothly. It also is ...
Using Dry Cabinets in High-Mix/Low-Volume Assembly
By Edward S. Wheeler, Director of Manufacturing Engineering, Trenton Technology Inc., Utica, NY
High-volume assembly provides numerous benefits to users: good process repeatability, large stocks of parts neatly dry packed and ready for use, and everything set up in tape-and-reel or matrix trays directly from the factory. In addition, when using high-volume assembly, the assemblers ...
Finding the Middle Path in PCB Cleaning
By Tom Forsythe, Vice President, Kyzen, Nashville, TN
One fundamental realization that often escapes people is that as things become smaller, the things inside them also become smaller and closer together. This last fact — the closer together part — is what can be challenging for electronics assemblers. It significantly impacts placement ...
Debunking Urban Legends about PCB Cleaning
By Mike Konrad, President and CEO, Aqueous Technologies Corporation, Rancho Cucamonga, CA
Within the cleaning sectors of the electronics assembly industry lays a strange mixture of science, tribal knowledge, contradictions and urban legends. As the electronics assembly industry again embraces cleaning as a mainstream process, it may be prudent to review the "conventional ...
