Testing and Qualification Levels

For high reliability applications such as aerospace, satellite, defence and medical electronics, Micross can offer Hi-Reliability screening on any size or style that can be processes and/or tested to customer specific reliability parameters.

Testing

Micross Components are able to support three categories of MIL-PRF-55342 qualified components.

• • Level T - Space Level Resistor to which each production lot will undergo Group A and Group B inspection. R-level Reliability rate
  • Level M, P, R, S - Established Reliability product levels to which failure rates will be established at 1% to 0.0001% / 1000hrs. Each lot is subjected to subgroups 1 and 2 of Group A (with the exception of 1000hrs Burn In)
  • Level C - Non-established Reliability product where mandatory testing such as Groups A and B are not required
• MIL-STD-202 Method 108 & 2011 release

Other Testing capabilities include:

• • Short Load Testing
  • Thermal Shock & Temperature Cycling
  • Bondability and Wire bond integrity testing
  • Moisture Resistance
  • Low and High temp exposure

• • TCR and VCT testing
  • Data Logging of DC Resistance
  • Life testing
  • Power Burn-In
