  • Consult the QA Department for additional approvals.

All of our high reliability, military, space level, and commercial parts are manufactured on the same production line. This ensures consistent quality for all our products. It is standard for all MSI parts to undergo a 100% electrical test and 100% visual inspection.  In addition, the parts are checked for conformance to a 1% AQL at Final QC Inspection.  The quality assurance department performs testing to MIL-PRF-55342, MIL-PRF-38534, and customer specific requirements.  The following list contains some of the testing performed at MSI:



Thermal Shock, Element Electrical, Visual Inspection, Solderability, Resistance to Solvents, & Power Conditioning (Space Level).



Resistance Temperature Characteristics, Short Time Overload, Solder Mounting Integrity, Bondable Mounting Integrity, & Wire Bonding Integrity.



Life Test, Thermal Shock, Low Temperature Operation, Resistance to Soldering Heat, Resistance to Bonding Exposure, Moisture Resistance, & High Temperature Exposure.



Element Electrical, Visual Inspection, & Wire Bond Evaluation.



Element Electrical, Visual Inspection, Wire Bond Evaluation, Temperature Cycling, Constant Acceleration, Voltage Conditioning (Aging), DC Leakage (Capacitors), Dielectric Withstanding Voltage (Capacitors), Dissipation Factor (Capacitors), & Salt Atmosphere (Packages).

Additional Testing:

MIL-STD-202, MIL-STD-883, MIL-PRF-38534, MIL-PRF-49464

Current Noise, Device Finish, Die Shear, Insulation Resistance (Capacitors), Q-Factors (Capacitors), SEM Analysis, Temperature Coefficient of Capacitance, & Visual Inspection.

  • Green Products Policy: Mini-Systems Inc. strides to become an environmentally responsible manufacturer. We are committed to ensuring that all products manufactured on behalf of our customers comply with governing legislation and/or customer specific requirements.

Our commitment to the production of quality components means success for our employees and customer satisfaction worldwide.  Mini-Systems’ performances reliability testing to insure its parts maintain the best quality. 

  • Thick Film QPL Resistors have an “S” failure rate (FR Level). MSI compiles >10,000,000 chip hours of life test a year.
  • Thin Film QPL Resistors have an “R” failure rate (FR Level). MSI compiles >3,000,000 chip hours of life test a year.
  • Non-QPL Thin Film Resistors compile >2,500,000 chip hours of life test a year with an average shift of +0.016% and no failures.
  • Our packages are manufactured with procedures that meet or exceed testing outlined in MIL-PRF-38534.
  • MSIRP (Mini-Systems Inc. Reliability Program).

Mini-Systems Inc. is committed to its customers. Most of our customers’ programs have long life cycles which require a steady flow of parts.  We would never discontinue manufacturing or obsolete a part type that would affect our customers’ supply.  If a part was purchased in the past, MSI will still manufacture it today.
