Stencil Design Using Regression:Following IPC 7525 a Way Better

Mar 25, 2010 | Subrat Prajapati; Process Engineering Larsen & Toubro Limited, Medical Equipment and Systems (EBG)

The complexity of Printed Circuit Assembly process is increasing day by day and causing productivity issues in the industry, introducing ultra fine pitch components (pitch less than 15mil) in PCA is a challenge to minimize risk of defects as solder short, dry solder. This paper is focusing on minimizing these defects....

DOE for Process Validation Involving Numerous Assembly Materials and Test Methods.

Mar 18, 2010 | Renee Michalkiewicz, Gaylon Morris; Trace Laboratories, Inc., Simin Bagheri; Celestica, Inc.

Selecting products that have been qualified by industry standards for use in printed circuit board assembly processes is an accepted best practice. That products which have been qualified, when used in combinations not specifically qualified, may have resultant properties detrimental to assembly function though, is often not adequately understood. Printed circuit boards, solder masks, soldering materials (flux, paste, cored wire, rework flux, paste flux, etc.), adhesives, and inks, when qualified per industry standards, are qualified using very specific test methods which may not adequately mimic the assembly process ultimately used....

Screening for Counterfeit Electronic Components

Mar 11, 2010 | Stephen Schoppe, Glenn Robertson - SMTAI Proceedings

Counterfeit products have been a growing problem worldwide, and the electronics industry has been no exception. Authentication of electronic components by electrical and physical testing can provide a cost-effective means of risk management, aimed at keeping counterfeits out of the supply chain. In this presentation, we will review sources of counterfeit components, and discuss the capabilities and limitations of test processes used for authentication. We will then present examples of component authentication using these tools....

Aiming for High First-pass Yields in a Lead-free Environment

Mar 04, 2010 | Mario Scalzo Senior Technical Support Engineer CSMTPE, Six Sigma Black Belt, Indium

While the electronics manufacturing industry has been occupied with the challenge of RoHS compliance and with it, Pb-free soldering, established trends of increasing functionality and miniaturization have continued. The increasing use of ultra-fine pitch and area-array devices presents challenges in both printing and flux technology. With the decrease in both the size and the pitch of said components, new problems may arise, such as head-in-pillow and graping defects...

Building Differentiated Products Through Shorter, More Predictable Design Cycles.

Feb 25, 2010 | Cadence

This paper will focus on two challenges: building differentiated products, which can enable systems companies to quickly penetrate a market, take a leadership position, and effectively counter or displace any competition; and build them faster. Clear differentiation also allows a superior value proposition, which will enable a stronger position on pricing with less need to circum to eroding ASPs. Differentiation can involve many factors, but this paper will focus on those related to the technology impact/usage that directly enables the design of products with shorter, more predictable design cycles compared to the competition....

Developing An Effective, Fast-Curing, Environmentally Sound Conformal Coating

Feb 10, 2010 | Phil Kinner; HumiSeal Europe

The electronics industry has recently undertaken the transition to lead-free processing as a direct consequence of the RoHS directive, which came into force in July 2006. However, this is unlikely to be the last transition required since the European Solvent Emissions Directive, 1999 is starting to be implemented and enforced by national governments. This is resulting in pressure on larger manufacturers, currently emitting more than 5 tonnes of solvent vapour per annum to take steps to limit and reduce their emissions....
