Ceramic to Plastic Packaging

Apr 15, 2010 | Michael D. Frederickson, EMPF Director; Barry Thaler, Ph.D. EMPF Technical Director Empfasis Technical Editor; Paul Bratt, Empfasis Editor.

As electronic products increase in functionality and complexity, there is an emphasis on affordability, miniaturization, and energy efficiency. The telecommunications, automotive, and commercial electronic markets are the leading drivers for these trends. These markets see high volume manufacturing with millions of units priced to the fraction of the cent. The choice of the packaging material for the electrical components for these markets can have a substantial effect on the cost of the final product. Therefore plastic encapsulated components are almost universally used in non-military applications over the conventional ceramic or metal electronic packages....

Advanced Electronic Connector Technologies

Nov 27, 2008 | Fred Verdi, Senior Manufacturing Engineer, ACI-EMPF.

Military electrical connectors have traditionally used very conservative design rules that provide the ruggedization needed for harsh military use environments. Commercial electronic connectors have typically used less conservative design rules that....

Selective Soldering Process

Jan 24, 2008 | Paul Bratt, Lead Package Engineer

Although many through-hole components are being replaced by their surface mount (SMT) counterparts, printed circuit boards (PCBs) are still being designed with both types of components. Often, there are interconnect hardware, displays, or other components that cannot withstand the exposure to the high temperature involved in the wave soldering process. They are generally soldered by hand. The challenge is to determine the optimal method manufacturers can use to solder these boards populated with mixed technology....

RF Packaging Advancements for Navy Applications

Oct 02, 2007 | Fred Verdi, EMPF Technical Director

The vast majority (99%) of the electronics market in North America is composed of products produced for commercial applications. The 1% share of the electronics market driven by Department of Defense (DoD) applications has created a niche market for RF qualified devices. The DoD, with its emphasis on COTS (Commercial Off The Shelf) and "Open" systems, is beginning to become more interested in using commercially oriented RF devices for military applications as a means to leverage the volumes and innovations of the commercial world....

Characteristics of Conformal Coatings

Aug 28, 2007 | Dave Poulin, Senior Materials Engineer, EMPF.

A conformal coating is defined as a thin polymeric material which covers the surface of an electronic assembly. These coatings are used to provide an electrically insulative and environmentally protective seal or cover to a completed printed circuit board (PCB)....

Reduced Oxide Soldering Activation (ROSA)

Jul 19, 2007 | Sam Pepe, Chemist, American Competitiveness Institute / EMPF

ROSA is a surface restoration technique that removes hard to reduce species like metal oxides or sulfides. At the time of its development, the focus was on solderability and compliance to environmental regulations. Industry trends and regulatory changes as a result of the Montreal Protocol were the driver for much of the concern over environmental compliance. The result was an increase in the development of no-clean and water soluble fluxes and the removal of halogenated cleaning chemistries....
