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. ...

Solder Preform Basics

Dec 14, 2009 | Paul A. Socha, Indium Corporation.

Solder paste is the most recognized form of solder used in electronics assembly today. A surface mount application depends on solder paste to attach the components to the circuit board. However, solder paste may not be the only solution. This is especially true when working with through-hole components or very large devices that require more solder than can be supplied by printed solder paste. In fact, quite often a PCB involves mixed technology that requires more than one form of solder. Solder paste is used for the surface mount components and solder preforms are utilized to attach the leads on through-hole components, avoiding wave or selective soldering....

Thermal Profiling: A Practical Approach to Reflow Profiling

Dec 14, 2009 | Liyakathali Koorithodi, Indium Corporation

In the lead-free era, thermal profiling has a critical role in the SMT assembly process. We discuss the profiling, tools, practical issues, and inspection methods of golden boards, and related tools. As the process window narrows, profiling equipment and/or thermocouple (TC) errors must be taken into consideration. In addition, the accuracy and attachment method of the thermocouple will significantly impact critical assemblies....

Recommendations for Installing Flash LEDs on Flex Circuits

Dec 09, 2009 | Shereen Lim

For the mobile market some PCB assemblies have been converted to flex circuit assemblies, in part because flex circuit assembly can be twisted or bent per the application needs. Flex circuits offer the same advantages as conventional printed circuit boards: quality, reliability, and high density....
