Test Services for Circuit Card Assemblies

At times, prototype and production builds may require test services to meet a level of test to be performed prior to shipment. This may entail basic functional testing, power-up testing, or perhaps post-assembly failure analysis, essentially troubleshooting an engineer’s R&D design if it’s not performing to its functional specifications. NPI Services has the test equipment and trained staff to perform such a variety of post-assembly test services for its customers.

NPI’s equipment list includes:

  • Tektronix (MDO4104-6) Mixed Domain Oscilloscope/Spectrum and Logic Analyzer

  • Tektronix (FCA3020) Timer/Counter/Analyzer

  • Tektronix (DMM4050) 6 ½ Digit Precision Multimeter

  • Tektronix (PWS4205, PWS4602) Programmable DC Power Supplies

  • Tektronix (AFG3251) Single Channel Arbitrary/Function Generator

  • Hubbell (HD100) Hi-Pot Tester

Circuit Card Assembly Test Services include:

  • Basic functional test: Customer supplied test procedure/script. NPI will verify and document product performance under controlled test input conditions.

  • Power-up Test: Validate PCB design integrity…no opens/shorts exist.

  • Troubleshoot PCB layout: If issues exist, “ohm out” PCB with power applied.

  • PCB failure analysis: Utilizing customer supplied schematics and assembly drawings, NPI will perform “top level” circuit design testing to determine failure mode.
