    • Acoustic Microscopy / Dye Penetrant Testing for PEMs
    • Fine and Gross Leak for Hermetic Packages
    • Wire Bond Pull / Shear
When would someone use DPA?
    • Typically all Space customers require lot-by-lot DPA for its EEE parts
    • DPA is also performed when new product or process is introduced for EEE parts. This provided early warnings of any potential Quality or Reliability issues with the part or process
What parts are DPA performed on?
    • Almost all EEE parts as defined by NASA. This includes Microcircuits, Discretes (diodes and transistors), Passives (capacitor and resistors), Connectors, Magnetics, PWM amongst others
    • Integra provides DPA services for all these parts
What are the various standards of DPA?
    • MIL-STD-1580 (Most commonly used)
    • PEM-INST-001 (most requirements refer to Mil-Std-1580)
    • MSFC-STD-3012 (most requirements refer to Mil-Std-1580)
    • SSQ 25000 Rev B (Space Station) (most requirements refer to Mil-Std-1580)
    • ESCC Basic Specification No. 21001 (European standard)
