Plasma Treatment: Dropping the Failure Rate


Whether in daily manufacturing or the development of new processes and products: surfaces and their properties play an increasingly important role in nearly all industrial areas. The surface of materials often have to be pretreated to prepare them for processes that will follow.

Selective Soldering: Pushing the Envelope


The entire concept of selective soldering is being squeezed as the demands for high quality soldering increase while board space continues to shrink. Today's challenge is to reduce the nozzle sizes available.

Why IPA-Water Extraction Fails!


The performance requirements for mission critical electronic assemblies are constantly increasing as component failures, particularly in the aerospace, automotive, medical and military industries, are simply not an option. Since failures are often due to insufficient cleanliness, cleaning ...

Advances in Fluid Dispensing Save Time, Production Costs


Automated fluid dispensing has been an integral part of the electronics assembly line for high-volume manufacturing for many years. Even jetting, which was introduced by Nordson ASYMTEK in 1994, is now an established technology. As electronic components become smaller and more complex, ...

Vapor Phase Making Strong Comeback


Vapor phase, also known as condensation soldering achieves a very gentle, reliable, and repeatable process. Vapor phase reflow was used back in the 80s — during the early days of surface mount technology — due to its excellent heat transfer capability. Heat transfer in vapor phase ...

Inline Wire & Cable ID


Many OEMs require that individual wires and cables used in their products be clearly identified with a mark or label. For some, such as in the military and aerospace markets, wire and cable identification (or "wire ID") is mandatory and the process is governed by stringent specifications ...

X-Ray Imaging: Some need-to-Know Basics


Electronic technology has given a great boost to real-time x-ray imaging. A tube was developed that could intensify the light from the intensifying screen. Called an "image intensifier," it is a vacuum tube with an input phosphor. Photons are converted to light and the light is converted ...

Thick Film Heaters Go Anywhere


It's a well known fact that passing current through a thick film resistor can transform it into a heating element. Such a phenomenon is a nuisance in thick film hybrid circuits where resistors need to operate at low temperature without long-term degradation to their electrical properties ...

Detecting & Avoiding Counterfeits


While the majority of counterfeit cases reported are associated with independent distributors, it's important to not label them as the cause, but rather to look to them for solutions. Understanding their processes and the measures...

Justifying AOI and Automated X-Ray


Two of the guiding philosophies for the implementation of test and inspection technologies are prevention and detection. Prevention places the priority on process control and elimination of defects by implementing corrective action. Detection focuses inspection efforts on ensuring that ...

Combining Board Cleaning and Testing


The U.S. space agency NASA has some of the most stringent electronics requirements in existence, and for good reason. NASA people still shudder over the most tragic example ever of a suspected circuit board cleanliness failure — January 27, 1967, when a circuit assembly in an Apollo ...

Automating Telecom Connector Assembly


Manufacturers of high-density telecommunication connectors have, for the last several years, been constantly redesigning their products in a race to satisfy ever higher demand for increased data transmission capabilities (baud rates). When one major manufacturer was ready to design ...

A New Approach to Using Boundary Scan


Board-level production test equipment, such as in-circuit testers, using third-party boundary scan tools, have gained in popularity. Such integration often provides little benefit over standalone boundary scan systems. While some of those solutions provide improved test coverage by ...

Improving Inspection of Lead-Free Solder


Lead-free solders are said to cause various problems, such as: lack of self-alignment, bridges, solder balls, insufficient wetting, dendrites, pits, voids and peeling of soldering land. Also, on miniaturized lands, there may occur insufficient melting of solder paste. Even though these ...

Shrinking Components, Highly Complex PCBs Drive AOI Design


The continuing trend toward the miniaturization of electronic packaging technologies is perhaps the most prolific driving force behind new AOI product development. The advent of 0201 and 01005 packages and the industry-wide acceptance of BGA, CSP and a host of small outline ultra fine pitch ...

Lead-free Selective Soldering Equipment


Selective soldering is a flexible, adaptable process that is increasingly applied to an ever-widening range of soldering tasks. Indeed, selective soldering has moved beyond the role of being a problem application solution and into the soldering production mainstream. Flexible innovations ...

Lead free Solder, Tips and Nitrogen


The RoHS deadline has come and gone but many manufacturing and service companies that aren't servicing international markets are still using leaded solders. With the future political outlook it is well within the possibilities (even likely) that a U.S. version of RoHS could be legislated ...
