A Case Study in Troubleshooting Shop Floor Rework Difficulties

Apr 05, 2007 | Martin Hogner; Martin Rework and Dispense Technic, Wessling/Munich, Germany, and Allen Sirois; Web Administrator, Manncorp Inc., USA.

Recently a large global player approached us with a problem. They needed an initial assembly solution for brand new components. Their boards and CSP specimens could not safely be soldered due to wetting problems at the solder joints....

Effects of Assebly Process Variables on Voiding at a Thermal Interface.

Apr 04, 2007 | Muffadal Mukadam, Jeff Schake, Peter Borgesen, Krishnaswami Srihari.

The present work offers a discussion and a first case study to identify and illustrate voiding mechanisms for a particular TIM between a heat spreader and the back of a flip chip. Pronounced differences were observed between stencil printing and dispensing in terms of initial void formation, apparently related to the specific properties of the material. Measurements of the effects of heat ramp rate and peak temperature showed the subsequent evolution and final void size distribution to be determined by the initial part of the cure profile up to the material gelling temperature....

Lead-free Rework Process For Chip Scale Packages

Mar 28, 2007 | Arun Gowda and K. Srihari, Ph.D. - Electronics Manufacturing Research and Services, Anthony Primavera, Ph.D. Consortium Manager - Universal Instruments Corporation

Legislation against the use of lead in electronics has been the driving force behind the use of lead-free solders, surface finishes, and component lead finishes. The major concern in using lead-free solders in the assembly and rework Chip Scale Packages (CSPs) is the relatively high temperatures that the components and the boards experience. Fine-pitch CSPs have very low standoff heights following assembly making inspection and rework of these components more difficult. One other concern pertinent to rework is the temperature of the neighboring components during rework. These issues, coupled with the limitations of rework equipment to handle lead-free reflow temperatures, make the task of reworking lead-free assemblies more challenging....

I Have an Idea for a New Product, but Now What?

Mar 13, 2007 | Jim Usery

Do you have an idea for an electronic product, the next must-have gadget, music or video system, time saver, or the greatest problem-solving device that was ever invented? Before you begin designing the product, there are a number of tasks that you must complete and issues that you must resolve before you have an actual product design that can be produced, marketed, and sold. This article will provide you with some guidelines to assist you in getting your idea turned into a successful design. Other issues, such as whether or not to apply for a patent for your product idea and in detail how a particular product should be advertised or marketed will not be addressed in this article....

Effect of Reflow Profile on SnPb and SnAgCu Solder Joint Shear Force

Mar 08, 2007 | Jianbiao Pan, Brian J. Toleno, Tzu-Chien Chou, Wesley J. Dee

Reflow profile has significant impact on solder joint performance because it influences wetting and microstructure of the solder joint. The degree of wetting, the microstructure (in particular the intermetallic layer), and the inherent strength of the solder all factor into the reliability of the solder joint. This paper presents experimental results on the effect of reflow profile on both 63%Sn 37%Pb (SnPb) and 96.5%Sn 3.0%Ag 0.5%Cu (SAC 305) solder joint shear force....
