Ensuring Success in PCB Manufacturing and Assembly, Part 2


Achieving success in printed-circuit-board (PCB) manufacturing depends upon proper planning and use of available tools. As detailed in the first part of this two-part article (see U.S. Tech, July 2015, p. 56), eight steps are required to ensure success in PCB manufacturing ...

How Functional Inkjet Technology Can Digitize PCB Fabrication


Launching a new, revolutionary technology requires not only the demonstration of added value to PCB fabricators and OEMs, but also the education and reassurance of users in order to overcome the psychological barriers to the acceptance of a new technology within a manufacturing environment ...

Material Choices Improve Auto Electronics Performance


Because transportation is of such global importance, it is no surprise that the automotive industry receives such a high level of regulatory expectations regarding performance, functionality, and efficiency. It is an exciting yet challenging time to work in the automotive industry. ...

New Tools and Processes Power Quick-Turn Assembly


Printed-circuit-board (PCB) assembly need no longer require days or weeks. Using the latest assembly machines and production approaches, it is now possible to provide customers with a PCB assembly quote in minutes and a fully assembled prototype PCB in 24 hours, following receipt of all required materials ...

Rethinking Final Testing of Smart Devices


Martin Cooper, former Vice-President of Motorola, changed the way most people communicate when he made the first cellular telephone call more than 40 years ago on the company's DynaTAC cellular telephone. The prototype telephone that Cooper used weighed 1.1kg and measured 228.6 x 127 ...

Testing Intermittent Failures for Cables and Cables Harnesses in Motion


Cables in motion can suffer fatigue and complete or intermittent failures, whether or not the motion is constant. Fortunately, cable and cable harness test systems can identify and pinpoint the source of even the most elusive intermittent failure in different types of cable assemblies ...

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 ...

How Clean Is Clean Enough for Reliability?


Dirt and residues trapped under bottom circuit terminations can affect performance due to shorter distances between conductors, higher pin out devices in smaller footprints, higher electrical field densities, and various environmental factors. No universal test method can ensure proper ...

Tester Aims for Zero Defects When Manufacturing PCBs


Zero defects for a manufacturer means never delivering a defective product to a customer. Manufacturers of printed circuit boards (PCBs) are doing absolutely everything in their power to make this happen — knowing full well that they cannot possibly achieve 100 percent zero defects ...

EMI Shielding Caulk Cures Quickly and Is Paintable

EMI shielding caulk provides EMI protection for military vehicle-mounted radar systems.
 

Shielding of electromagnetic interference (EMI) is critical to many electronic systems, especially for military radar shelters. Contributing to this overall shielding is an EMI shielding caulk developed by Parker Hannifin's Chomerics Div. — a caulk that provides numerous mechanical benefits in addition to improved EMI ...

Ensuring Success in PCB Manufacturing and Assembly, Part 1


Printed-circuit-board (PCB) manufacturing and assembly represents a crucial stage between the design of the next great technological device and the finished product. All critical business metrics, including cost, quality, and delivery, are directly affected by performance during production ...

Flexible System Checks Cables and Harnesses


Wire cables and harnesses come in many shapes and sizes and testing such assemblies requires a flexible test system. The CableEye® test system from CAMI Research is a personal-computer-based diagnostic tool that can evaluate the basic electrical properties of cables and harnesses ...

Optical Encoders Help Measure Material Fatigue


Fatigue testing is one way to evaluate how different materials will behave under different environments and operating conditions. Test systems developed for such characterization, such as the equipment from Norwood, Massachusetts-based Instron can examine the behavior of different materials ...

The Fundamentals of Closed-Loop Solder Paste Inspection


Solder paste inspection (SPI) can provide invaluable information about electronic production quality. It is one of the first automated inspection systems employed in any automated printed-circuit-board (PCB) production line, and can offer details about the integrity of soldered connections ...

Surface-Mount Components Help Shrink Circuit Dimensions


Surface-mount components have earned their places in today's electronic circuits, saving a great deal of printed-circuit-board (PCB) space without sacrificing the performance of much larger components. Components now available in SMT housings include basic "building-block:" components ...

The Benefits of Using Aluminum as a Conductor


Choosing conductive metals for different industries and applications is often a challenge. Copper is often used in cables and wires for its excellent conductivity and malleability. But it is relatively heavy and expensive compared to aluminum. Switching to aluminum, which is lighter ...

Unwired Switches Are Wireless Without Batteries


Switches that operate without wired connections or batteries are now available from Cherry, a brand of ZF Electronic Systems Pleasant Prairie, LLC. The switches use the physical actuation of the switch as the source of power, harvesting energy through an innovative penny-size micro ...

Vibration Testing: Exposing the Weak Link


Weak links exist in all electronic designs. Over time, and in the right conditions, they will manifest themselves. Vibration testing attempts to uncover those weak links in advance by imposing realistic operating conditions. By developing a circuit card assembly (CCA) for testing, it is ...

When to Use Litz Wire


Throughout the electronic design process, involving anything from inductors and transformers through systems, optimizing efficiency and minimizing heat rise are major concerns. A decision on the type of wire to use can impact the thermal performance of a design, with choices including ...

Do We Really Need SMT-Specific Material Management?


Successful manufacturing of electronics in North America requires a great deal of flexibility. With demands for so many different electronic products, including complex modules, prototypes, small lot sizes, pre-production runs, short runs, tight deadlines, and the need for high quality ...
