Custom Design & Engineering Services — Experience the DFI Tech Difference

Our customer’s success begins with conceptualizing and designing and prototyping their product. The right design and engineering team makes all the difference, whether bringing a new product to market or re-launching an existing product with new features. DFI Tech’s engineering team is co-located and integrated with our manufacturing team to ensure that products are designed for manufacturability, sustainability, and profitability from Day 1. During concept development, we capture the customer’s requirements while considering the product environment, functionality, compatibility, performance, stability and reliability.  We make sure all of it is represented and laid out in the design.  The schematics are closely reviewed by our senior engineers and cross-referenced with our extensive common-parts database to ensure accuracy and manufacturability.  Our goal is to provide great design with the most readily available components that can be obtained in large quantities and at the greatest cost savings.

During the prototyping and validation phases, we rigorously test the product sample to ensure it meets the requirements set out during the concept phase.  This process includes signal integrity tests, extended functional and thermal tests, thermal shock, shock and vibration, compatibility, EMI, and ESD.  All design and testing activities is performed in-house, so feedback is immediate and any necessary design changes happen quickly.  We understand that design engineering is critical to the overall success of your project and are committed to providing not only the most experienced engineers, but a fast design cycle to enable you to take your product to market faster. Our value-added engineering services are also focused on reducing unit cost in both manufacturing AND service/support, while accelerating time to market for your products.

DFI Tech Design & Engineering—Comprehensive Services that Partner with Your Resources

prototyping-station At DFI Tech we offer a comprehensive set of design and engineering services.  We understand that every customer is different so we are committed to tailoring our approach to meet your needs and integrate seamlessly with your engineering, manufacturing, quality control, and service personnel. The design engineering services we provide:

  • First and foremost you have access to our Product Development Process which includes:
    • Product conceptualization and definition of specifications
    • Cost estimation
    • Materials evaluation
    • Prototyping
    • Engineering Validation Testing
      • Based on the prototype, we verify that all of your desired features are present and function correctly.  Testing may consist of power-on and functional tests, along with initial EMI/EMC scans, thermal tests, safety, signal integrity checks, mechanical fit and debugging.
  • Design Verification Testing
    • This phase follows EVT and validates that the features perform to your specifications.  This may include full validation and certification testing that covers EMI/EMC, safety, and mechanical endurance with shock and vibe which will determine such characteristics as MTBF.  While some of the tests are repeated from EVT, their purpose here is to finalize your product.  If we’re satisfied with the results, we will develop a tooling
  • Manufacturing Verification Testingfunction-testing
    • Here we verify that your product is ready for mass production with a pilot run.  At this phase your product will undergo its most rigorous testing to make sure it is ready for release
