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....

Micro-Sectioning of PCBs for Failure Analysis

Jan 13, 2010 | Bob Wettermann

Micro-sectioning (sometimes referred to as cross-sectioning)is a technique, used to characterize materials or to perform a failure mode analysis, for exposing an internal section of a PCB or package. Destructive in nature, cross-sectioning requires encapsulation of the specimen in order to provide support, stability, and protection. Failures that can be investigated through micro-sectional analysis include component defects, thermo-mechanical failures, processing failures related to solder reflow, opens or shorts, voiding and raw material evaluations....

Advanced Thermal Interface Materials for Enhanced Flip Chip BGA

Jan 06, 2010 | Punit Kohli, Martin Sobczak, Jeff Bowin, Michael Matthews - Henkel / Ablestik Laboratories

Increased functionality and performance requirements for microprocessors and ASICs have resulted in a trend to package these devices in the flip-chip BGA form factor (FCBGA). Because these devices use in excess of 40-100 Watts of power, their packages must dissipate heat in an extremely efficient manner. Most semiconductor companies have developed some type of thermally enhanced FCBGA package that provides heat dissipation through the back of the die to a heat spreader....

Horizontal Convection Reflow Technology Defined

Dec 23, 2009 | APS Novastar

Leading up to the development of lead-free soldering alloys, Horizontal Convection* was developed for the reflow process. Getting the correct temperature profile, with the narrow process window in lead-free applications, is now more important than ever. In each chamber or “zone”, air is circulated toward one side of the oven above the PCB and toward the opposite side of the oven below the PCB, forming a “cyclone” around the board. The forced air circulation results in a uniform temperature profile along the entire circuit board assembly. This technology is ideal for the precise profiles needed for lead free soldering....

Why Switch From Pure DI-Water to Chemistry

Dec 22, 2009 | Dr. Harald Wack, Umut Tosun, M.S.Chem.Eng., Dr. Joachim Becht, Dr. Helmut Schweigart

While most cleaning applications in the North American market rely on cleaning with DI-water only, for removing OA fluxes in first place, recent market studies show that water has reached its limitations in cleaning performance while favoring usage of aqueous processes. The term aqueous implies the use of aqueous-based chemistries with active ingredients and are usually diluted with DI-water. The nature of these active ingredients in the aqueous chemistries varies between manufacturer and his R&D knowledge. ...
