M+ RUGGED + IPC Class 3 (BKUP)

---

When it comes to electronics built for aerospace, defense, and other mission-critical environments, reliability isn’t optional — it’s the foundation. That’s why MEMKOR builds Military-grade SSDs to IPC Class 3, the most rigorous standard defined by the IPC (Association Connecting Electronics Industries) for printed circuit boards (PCBs) and assemblies.

IPC defines three classes of electronic products:

• Class 1: General use electronics, where function is the primary requirement (e.g., consumer gadgets).
• Class 2: Dedicated service electronics, where extended life and consistent performance matter, but some downtime is acceptable (e.g., industrial equipment).
• Class 3: High-performance, harsh-environment electronics, where uninterrupted service and long-term reliability are critical. Examples include avionics, satellites, defense systems, and medical life-support.

Class 3 is the gold standard, requiring the tightest tolerances, the most stringent inspection criteria, and the highest workmanship standards in the industry.

Building to IPC Class 3 means going beyond “good enough.”

It involves:

• Annular Ring Integrity
  Every via must maintain full copper around the drilled hole — no tangency or breakout allowed.
• Plated Through-Hole Quality
  Tighter requirements for copper thickness and uniform plating to ensure long-term durability.
• Solder Joint Excellence
  Only flawless solder joints are acceptable. Any voids, cracks, or insufficient wetting are rejected.
• Material Reliability
  Strict control of laminates, finishes, and solder masks to withstand temperature swings, vibration, and harsh conditions.
• Enhanced Inspection & Testing
  More comprehensive visual inspections, microsections, and electrical tests to verify conformance.

Choosing Class 3 provides significant advantages for mission-critical programs:

• Assured Reliability: Boards are built to perform flawlessly for their entire service life.
• Environmental Resilience: Proven durability under extreme temperature, shock, and vibration.
• Compliance Confidence: Alignment with aerospace and defense quality requirements.
• Reduced Risk: Higher yield and fewer in-field failures compared to lower-class builds.

At MEMKOR, we understand that failure is not an option in aerospace and defense. That’s why we offer IPC Class 3 manufacturing for both standard and custom form factors. Whether you need rugged SSDs in familiar sizes or uniquely engineered solutions for demanding environments, MEMKOR ensures every board is built and inspected to the highest standard of reliability.

MEMKOR: Delivering IPC Class 3 quality — where mission success depends on it.

M+ RUGGED SSDs are engineered for extreme environments where conventional storage fails. Designed and tested to meet MIL-STD-810G standards, these rugged solid-state drives deliver reliable performance under high shock, vibration, and extreme operating temperatures  ranging from -55°C to +95°C.

MEMKOR SSDs are trusted in defense and aerospace industrial systems where data integrity and mission success depend on durable, field-proven hardware. Available in a variety of form factors and interfaces, M+ RUGGED products are ideal for ground vehicles, airborne platforms, naval systems, and space-constrained deployments. Whether you’re operating in combat zones, high-altitude flights, or unmanned systems, M+ RUGGED provides mission-ready data storage built to survive and perform—even in the harshest environments.

Military environments demand durability. From arctic temperatures to desert heat, military-grade SSDs must operate flawlessly under extreme conditions. The M+ Rugged SSD is purpose-built for the rigors of these environments, ensuring reliable performance no matter where duty calls.

MEMKOR SSDs are designed with MIL-STD-810F/G requirements in mind, as our mission is to focus on solid state storage solutions capable to operate anywhere in the world and under any circumstances. While we offer commercial versions, we design, select components, build and test (and test, and test) to ensure these are truly Military-grade SSDs with long life, no maintenance, and solid health monitoring capabilities. All Military-grade SSDs can be conformally coated, built using special Bill of Material, and undergo  the rigorous multi-day production testing spanning across SSD operational functions and specified deployment environment.

All MEMKOR Military-grade SSDs are hardened through design and manufacturing to withstand harsh temperatures, humidity, and altitude. When other SSDs start throttle down performance at high temperatures, MEMKOR SSDs continue to perform. The need to meet different vibration and shock requirements lead to different levels of ruggedization in the design approach. As a result, MEMKOR TANGERINE and ORANGE-series SSDs comply with applications up to 16.3 gRMS vibration profile. If you need higher resilience levels, consider the MEMKOR BLACK-series SSDs successfully tested to 30 gRMS vibration levels. Need higher resilience, contact us.

The standard SATA connectors on 2.5" drives are rated for a very low vibration level (6gRMS) and a low number of insertions (~125-200). Addressing both issues at the computer system design level, and with no change to SSD, requires extra engineering time, increases hardware footprint and cost. As an alternative, MEMKOR offers two options.

The optional HiVibe© connector is built using field proven Hyperboloid technology. It eliminates the need for extra effort and extra hardware and provides virtually unlimited number of SSD insertions as well as ruggedizes the SATA plug-receptacle connection to 30gRMS vibration level.

The optional Smiths Interconnect Nebula connector also uses hyperboloid contacts to achieve immunity to shock and vibration fretting. The Nebula connector supports up to 100,000 mating cycles and is rated for operation up to 30g vibration.

Both the HiVibe or Nebula are available as an option on the BLACK series 2.5" SATA SSDs.

MEMKOR BLACK Series SSD provides the highest level of ruggedization suitable for the most adverse environments known to man and machines.

Customers have the option for PCBs to be manufactured in accordance with IPC-6012 Class 3, and assemblies to comply with IPC-A-610 Class 3 requirements for high-reliability aerospace and defense applications. More info about IPC Class 3.

When reliability can make the difference between mission success and failure, M+ Rugged delivers by ensuring that your data remains securely accessible, even in the toughest operational environments.
