Testing and Screening

Mil-Spec Components

We offer a broad spectrum of value added testing services. We partner with several independent test labs. Our value added testing and screening capabilities are being utilized more frequently. Some of the reasons for this include :

• Obsolescence of mil spec devices.
• Customer drawing requirements specify selected parameters.
• Re-screening requirements
• Concern over influx of counterfeit parts from China

Here are examples of the testing services we offer:

• Group A & B
• Basic electricals
• Burn in
• Bond Pull and Die Shear
• Full blown MIL screening or re-screening to JANTX and 883 Level*
• Steam Aging and Solderability Test Stations
• Solder Tinning & Lead Cleaning
• PIND (Particle Impact Noise Detection)
• Constant Acceleration (Centrifuge)
• Marking and Resistance to Solvent Test
• Optical Microscope Systems for Internal Visual Inspection (Failure Analysis)-SEM
• Hermeticity Seal Detection (Fine and Gross)
• Pressurization System for Gross (Fluorocarbon) and Fine (Helium)
• Leak Detection

*Note: All screening of semiconductors to military specifications is performed at a DSCC- VQC NILL-STD 883 certified lab. In addition to semiconductors we also offer testing on relays for their basica electrical performance and cable assmblies to ensure continuity, insulation resistance, and dielectric breakdown.

ruggedized and fully tested pcb manufacturing and assembly services

Gemini Electronics offers years of experience working with Mil-Spec requirements and the challenges they bring. We manufacture products to meet both industrial and MIL-PP-55110 requirements. We understand the detail that is required at every step of the process from quoting through shipping, meeting every requirement defined by the customer and any specified MIL Standard.

Our Military and aerospace designs demand  compliance with ever-increasing compliance for growing functionality and reliability within extreme environments. We utilize advanced design and layout techniques and 100% design-for-test (DFT) coverage with special attention to Thermal management and EMI / RFI.

There are several key design and layout considerations to make military and aerospace PCBs more robust,
these include using correct mil-spec components, designing in an extra cushion of current, maintaining the
right aspect ratios, separating power and ground planes, keeping signals clean and properly shielded,
verifying impedance calculations and performing pre-layout simulations, using proper termination techniques,
adding an extra cushion for mechanical holes and dimensions, maintaining stack up considerations during
PCB layout, keeping immaculate assembly notes, specifying an exact drill chart, and defining the proper
board material.
