ISI has a variety of electronic test equipment and capabilities. Test development can be wholly developed by ISI or it can be jointly developed by ISI and Customer, which is typical for functional tests that replicate actual customer usage. ISI performs testing in-house, as well as utilizes third-party suppliers when necessary.

Qualification Testing:

As a requirement for the project, ISI will develop and execute a qualification plan for the final product. This is typically a suite of tests to EIA/JESD and/or MIL-STD requirements.

The qualification test is specifically developed depending on the part design, how it will be used, and what environment it will be exposed to. Typical elements of product qualification testing include:

  • Physical dimensions / first article report
  • Mechanical testing (solder ball sheer, wire bond pull, resistance to solvents, etc.)
  • Preconditioning (Emulate SMT manufacturing process if developed product will be subject to solder attach to higher level motherboard. Includes moisture exposure and multiple reflow cycles.)
  • Temperature cycling
  • Operating life testing
  • Shock and vibration testing
  • Electrical testing
  • Boundary scan / JTAG
  • Functional testing
  • Signal integrity testing
  • Impedance loss
  • Temperature Testing
  • Differential
  • Crosstalk
  • Single-ended crosstalk
  • Electrical parametric testing
  • Shorts and opens testing

Methods of Inspection:

  • X-ray solder joint inspection
  • Nikon NEXIV optical coordinate measurement machines, optical and laser capabilities
  • RVSI high-speed laser system for interconnect presence, coplanarity and flatness
  • Ionograph cleanliness testing
  • XRF x-ray fluorescence analyzer
  • Laser-mark serial number traceability


Our quality system has been audited to establish ISI as an approved supplier by top-tier OEMs in a wide
range of industries including: military, aerospace, data storage and networking, telecom, commercial,
supercomputer, and industrial.

ISO Certification:

ISI was awarded ISO 9001:2008 certification by Perry Johnson Registrars, Inc. in 2009. ISI was originally certified to ISO 9001:1994 in 2000 and upgraded to ISO 9001:2000 in 2003.
