CE: Electrical Engineering
 
 Design and Simulation Tools:

  • SPICE and similar programs for analog simulation
  • PADS PCB design tools for printed wiring board design
  • Altera, Actel, and Xilinux are used to support PLD/FPGA development and simulation
  • LabVIEW to extend the capabilities of laboratory instrumentation.

    Electrical engineering staff can also utilize other CAE design software packages such as OrCAD, PADS Logic, E3, and various vendor-specific embedded software IDE's.

    IDEAS, AutoCAD, and SolidWorks mechanical CAE tools are used for chassis, panel, and test fixture designs. MSOffice products are used for documentation and support tasks using VBA for scripting and task automation.

    Group electrical and computer engineers are fluent in a number of standard programming languages including C, C++, Forth, Fortran, IDL, Assembler, BASIC, and Pascal; and script interpreters such as TCL and PERL. They are also proficient with common operating systems such as Linux, UNIX, Windows, Windows NT, and DOS, in addition to the custom real time systems that are developed and used in the design and test of the hardware being constructed.

    Other Technical Resources:

    Other resources include:

    • PWB construction for both plated through-hole and Surface Mount Devices.
    • Electronic production stations equipped with Metcal soldering and desoldering tools utilizing direct power technology, for the construction of PWB assemblies and/or cable assemblies.
    • Fully equipped OK Industries MTR-5000 surface mount device installation and rework station.
    • High bay assembly and integration area with dual overhead gantry cranes for large system integration.
    • Complete on-site machine shop for chassis, fixture, and panel work.

    Additional in-house resources are available for the preparation, execution, and verification of electronic production processes for PWB and cable assemblies. These include: ventilation hoods, flow benches, microscopes, crimp tools, and small and large environmental test chambers--Thermotron S-27-3800 with a -65C to +180C (-85F to +356F) temperature range and 36x36x36 inch interior.

    CE laboratory technicians are trained and certified to comply with the following NASA Workmanship Standards:

    • NASA-STD-8739.3 Soldered Electrical Connections
    • NASA-STD-8739.4 Crimping, Interconnecting Cables, Harnesses, and Wiring
    • NASA-STD-8739.7 Electrostatic Discharge Control (Excluding Electrically Initiated Explosive Devices)

    SAO technicians are also familiar with other standards such as ANSI/IPC-A-610 "The Acceptability of Electronic Assemblies". They are experienced in the use of light machining tools, and in the handling of materials common to PWB assembly work including staking compounds and the application and removal of conformal coatings.

    Electrostatic Discharge (ESD) countermeasures that are consistent with MIL-STD-1686 and NASA-STD-8739.7 are implemented in all work areas on the production floor, and in FED-STD-209 compliant clean rooms
