Sandia National Laboratories

For more than 60 years, Sandia has delivered essential science and technology to resolve the nation's most challenging security issues.


National security is our business. We apply science to help detect, repel, defeat, or mitigate threats.

Sandia National Laboratories is operated and managed by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation. Sandia Corporation operates Sandia National Laboratories as a contractor for the U.S. Department of Energy’s National Nuclear Security Administration (NNSA) and supports numerous federal, state, and local government agencies, companies, and organizations.

As a Federally Funded Research and Development Center (FFRDC), Sandia may perform work for industry responding to certain types of federal government solicitations. The solicitation must allow FFRDC participation and meet the requirements of Sandia's management and operating contract with DOE/NNSA.

A strong science, technology, and engineering foundation enables Sandia's mission through a capable research staff working at the forefront of innovation, collaborative research with universities and companies, and discretionary research projects with significant potential impact.

Although most of Sandia's approximately 10,000 employees work at Sandia's headquarters in Albuquerque, New Mexico, or at its second principal laboratory in Livermore, California, others are working at various sites in the U.S. and abroad to deliver innovative and reliable solutions in a changing world.

Effects Of Storage Environments On The Solderability Of Nickel Palladium- Gold Finish With Pb-Based And Pb- Free Solders

Mar 02, 2022 | Edwin Lopez, Paul Vianco, Samuel Lucero, and Carly George

The solderability of a nickel-palladium-gold (Ni-Pd-Au) finish on a Cu substrate was evaluated for the Pb-free solder, 95.5Sn-3.9Ag-0.6 Cu (wt.%, abbreviated Sn-Ag-Cu) and the eutectic 63Sn-37 Pb (Sn-Pb) alloy. The solder temperature was 245ºC. The flux was a rosin-based mildly activated (RMA) solution. The Ni-Pd-Au finish was tested in the as-fabricated condition as well as after exposure to one of the following accelerated storage (shelf life) regiments: (1) 33.6, 67.2, or 336 hours in the Battelle Class 2 flowing gas environment or (2) 5, 16, or 24 hours of steam aging (88ºC, 90%RH)....

Materials Compatibility and Aging for Flux and Cleaner Combination

May 30, 2016 | Kim M. Archuleta, Rochelle Piatt

New engineered cleaning and defluxing agents promise great improvement in cleaning and reliability for electronic assemblies. As complexity grows and dimensions shrink in high reliability electronics, the need for materials compatibility and effectiveness in cleaning and rinsing is vital....
