Engineering Design

At LCR, we take a holistic approach to system design and integration including packaging, signal flow analysis, power envelope, thermal management, I/O requirements and payload integration. Our team of industry veterans brings decades of skills and applied knowledge to the design of our rugged deployment chassis, enclosures, high speed backplanes and development chassis supporting mission critical defense applications.

Supporting New Program Designs

LCR Electronics engineering designOur engineers are established in a variety of disciplines including electrical, mechanical, software, test and systems engineering. We combine experienced leadership with fresh perspectives and new ideas to form a knowledgeable and engaging staff ready to assist our customers from initial requirements review through all stages of solution realization, manufacturing and post deployment support. For decades, US DoD programs have learned to rely on LCR.

Design Tools and Expertise

We use leading edge design tools to ensure optimal results and to provide a comprehensive overview of the desired system.

Thermal Analysis

Heat dissipation in embedded systems, especially in VPX based installations is a key focal point in any chassis design. Thermal management is a top priority at LCR and SOLIDWORKS Flow CFD (Computational Fluid Dynamics) is used to evaluate and optimize the thermal capabilities and limits of every chassis we design. We analyze the behavior of the design under adverse temperatures and thermal load conditions, checking for hot spots and seeking areas of improvement. LCR is a recognized leader in conduction cooled, air cooled and hybrid air and liquid over conduction chassis solutions.

Structural Analysis

High shock and vibration are the norm in rugged defense applications and the structural integrity of any packaging solution is crucial to protecting mission critical electronics. Our experts use SOLIDWORKS Simulation to zero in on the stresses and strains of packaging under internal and external loads. SOLIDWORKS helps to reduces costs and the need for rework during the development phase. Optimization is achieved through analyzing the behavior of the design under adverse static and dynamic load conditions.

3D CAD Modeling

SOLIDWORKS is employed throughout the chassis mechanical and electrical design process starting with initial planning, detailed visual conceptualization, feasibility review, modeling and creating prototypes. 2D parametric based drawing creation using DXF, DWG, STEP, IGES, STL and other file formats.

3D Printing

3D printing has come increasingly into use in the manufacturing sector. At LCR, we’ve been employing and honing our skills in 3D printing for years. Using in-house equipment, we create engineering models, prototypes, production components, connectors, tooling and fixtures to support our designs beginning from the early development stages. Liquid cooled chassis often require intricate fluid paths that benefit from the precision of 3D printing. Our engineers are experienced in the use of leading edge printers and various high strength materials onyx, fiberglass, Kevlar and carbon fiber.

Design Validation Testing (DVT)

Extensive test plans are created to verify every step of a design meets pre-determined specifications and performance goals. DVT testing may include some or all of the following:

  • Power Load Testing
  • Functionality Testing
  • Continuity Testing
  • Mechanical Fit Verification
  • Thermal / Airflow Testing
  • Signal Integrity Testing
  • Temperature Testing
  • Environmental Testing
    • Shock Testing
    • Vibration Testing
    • EMI Testing

Backplane Design for High Speed Signal Integrity

VPX systems are becoming synonymous with high speed signal requirements and LCR is a leading supplier of custom backplanes for VPX and SOSA-aligned modules. At LCR, we’re working to meet the evolving and ever increasing demands of leading edge communication protocols. Our design teams are focusing on the highest levels of signal integrity in backplanes with signal speeds reaching 25Gb/sec supporting mission critical equipment. Backplane and custom PC board designs use MentorGraphics PADS ES for schematic capture, component and circuit definition, layout, size and space parameter definition to ensure every trace, layer, connector, via and transition is characterized and take into account.

LCR engineering teams are located in both our Jeffersonville, PA and Jackson, MS offices.
