Optimizing Batch Cleaning Process Parameters for Removing Lead-Free Flux Residues on Populated Circuit Assemblies

Sep 18, 2009 | Steve Stach, Austin American Corporation, Mike Bixenman, Kyzen Corporation

Electronic assembly cleaning processes are becoming increasingly more complex because of global environmental mandates and customer driven product performance requirements. Manufacturing strategies today require process equivalence. That is to say, if a product is made or modified in different locations or processes around the world, the result should be the same. If cleaning is a requirement, will existing electronic assembly cleaning processes meet the challenge? Innovative cleaning fluid and cleaning equipment designs provide improved functionality in both batch and continuous inline cleaning processes. The purpose of this designed experiment is to report optimized cleaning process parameters for removing lead-free flux residues on populated circuit assemblies using innovative cleaning fluid and batch cleaning equipment designs....

Fluid Flow Mechanics Key To Low Standoff Cleaning

Sep 18, 2009 | Harald Wack, Ph.D., Umut Tosun, Naveen Ravindran, Sylvain Chamousset, Joachim Becht, Ph.D.; ZESTRON, Steve Stach, Austin American Technology Corp.

In recent years, various studies have been issued on cleaning under low standoff components; most however, with incomplete information. It is essential to revisit and describe the latest challenges in the market, identifying obvious gaps in available information. Such information is crucial for potential and existing users to fully address the cleanliness levels under their respective components. With the emergence of lead-free soldering and even smaller components, new challenges have arisen including cleaning in gaps of less than 1-mil....

Non-Contact Streaming Technology Enhances the Dispense Process

Sep 16, 2009 | Speedline Technologies, Inc.

The dispensing industry within electronics manufacturing represents a very diverse marketplace indeed; many different materials can be applied in many different ways. One high-growth area in this market is underfill, driven by the explosive demand for hand-held devices (HHDs). This segment is comprised of popular consumer goods, such as cell phones, mp3 players, GPS navigators, PDAs, portable games and ultra-mobile PCs. A new, non-contact dispense technology, known as Streaming, has recently been introduced to specifically address the incumbent needs associated with underfill....

Screen and Stencil Printing Processes for Wafer Backside Coating

Sep 09, 2009 | Mark Whitmore, Jeff Schake.

Stencil printing equipment has traditionally been used in the surface mount assembly industry for solder paste printing. In recent years the flexibility of the tool has been exploited for a wide range of materials and processes to aid semiconductor packaging and assembly. One such application has been the deposition of adhesive coatings onto the backside of silicon wafers....

Model Management for Predictive Accuracy

Sep 02, 2009 | Accuracy Competence Management, Assembléon BV.

The current trend of miniaturization in products and substrates is expected to continue in most advanced electronic products. Telecommunication and computer applications typically need high density connection boards incorporating smaller passive components, finer pitch IC’s and area array packages. The key factor in the technically successful evolution is the development of new interconnection processes, such as the use of conductive adhesive with very fine grained inter-connection materials....

AOI-AXI Duo Improves Product Yield

Aug 26, 2009 | David Upton

Automated optical inspection (AOI) and automated X-ray inspection (AXI) have been around for some time in various configurations and both have played a role in improving the quality of circuit boards. While some companies opt for one technology over the other, each form of inspection contributes its own unique benefit to the manufacturing process....

De-fluxing Eases

Aug 19, 2009 | Mike Konrad, President, Aqueous Technologies

There are several advantages to using a contract assembler. One of which is maintaining the ability to dictate desired results. Therefore, how those results are achieved becomes someone else's concern. When you combine this with the fact that many contract assemblers are not accustomed to saying "no," you become a witness to the birth of innovation....

The Environmental Impact of Pick-and-place Machines

Aug 12, 2009 | Sjef van Gastel

Energy labels are a key part of global attempts to reduce consumption of environmental resources. They inform customers of the future consequence of their purchases. There are now many national and other energy labels covering houses, cars, lamps, washing machines and dryers, air conditioners, etc. The EU Energy using Products (EuP) directive also is working on classifying industrial applications to set rules for future energy reductions. These rules are at least three years away; until then, there are no energy labels for industrial manufacturing equipment....
