End-to-End Testing Processes

Our testing processes begin with the design & development phase. Components and circuits are tested and retested at every step until the successful prototypes are built, tested, and validated.

Testing continues during the manufacturing process, and we have the capability to design and build our own automatic testing equipment required for each unique product. Board Level Testing utilizes automated optical inspection using cameras and optical part recognition. Once the Boards are assembled, they are subjected to In-Circuit Tests and Manufacturing Defects Analysis. X-ray Examinations are also conducted. Automatic Test Equipment is also used to provide a final function test for products before they are shipped to the customer.

In addition, the product test group at John Deere Electronic Solutions can provide comprehensive testing for numerous industry standards for products ranging from circuit boards to complete electrical systems.

Proper testing is essential to ensure that products will perform in extreme environments. Because of this, John Deere Electronic Solutions Test Labs is accredited by the American Association for Laboratory Accreditation (A2LA) to perform testing in compliance with ISO/17025. We realize the importance of maintaining quality throughout all of our processes.

 To gain accreditation, A2LA assessors rigorously verify the technical competence of our people, equipment, and methods based on ISO/IEC 17025. These are some of the industry's most thorough and stringent on-site assessments. Then, we are fully reassessed on a regular basis to make sure our capabilities continue to meet world-class standards.

 A2LA accreditation also insures acceptance of test and calibration data through mutual recognition agreements with multiple international governing bodies including the International Laboratory Accreditation Cooperation (ILAC), Asia Pacific Laboratory Accreditation Cooperation (APLAC), European cooperation for Accreditation (EA), and the Inter-American Accreditation Cooperation (IAA C).
