Quality & Reliability
In defense procurement, reliability is proven by equipment and process, not by a line in a brochure.
Design through production, one roof
Semiconductor IP design, product design, SMT assembly and test all happen in-house. Whether a fault sits in the controller or in the assembly, the same team traces it.
Domestic design, dependable supply chain
The core design assets are held in Korea, so a foreign vendor’s end-of-life notice or an export-control decision does not dictate the schedule. In defense procurement, continuity of supply is reliability.
Long-term supply
From the 2005 PATA SSD onward we keep shipping interfaces the market abandoned. Legacy support is a commitment, not a leftover.

Environmental
Defense-grade environmental specification
The figures below apply across the PaxDisk SSD line-up.
| Item | Specification | Note |
|---|---|---|
| Operating temperature | -40°C ~ +85°C | Common to the defense and industrial grades. Custom builds go down to -60°C. |
| Shock | 1,500G, 0.5ms | Common to the whole line-up. |
| Vibration | 16.32G rms | Common to the whole line-up. |
| Altitude | -1,200 ~ 120,000ft | Common to the whole line-up. |
| Humidity | 5% ~ 95% | Common to the whole line-up. |
Per-product environmental figures are on each product page. Test reports are shared, within the limits we are permitted, alongside a quotation or technical enquiry.
Infrastructure
Test & production infrastructure
Every item below is real equipment recorded in the company timeline.
2008
Thermal shock chamber
In-house verification of the -40°C to +85°C defense-grade temperature range.
2009
SMT line
Design through assembly in-house, keeping the supply chain short.
2010
20GHz-class measurement equipment
Direct signal-integrity measurement for high-speed serial interfaces (SATA 6Gbps, PCIe).
2009
Corporate R&D institute
Founded 2009; runs both semiconductor IP design and product development.
Lab & Measurement
Test & measurement equipment
From device characterisation (I-V, LCR) through RF spectrum and 20 GHz TDR to SATA-class high-speed serial compliance — we own the instruments needed to measure what we design.
High-speed serial
High-speed serial & compliance
Signal integrity and standards compliance of high-speed serial interfaces such as SATA are tested in-house. The company that designed the interface IP measures the signal itself.
Tektronix
DSA71604
16 GHz real-time digital serial analyser — eye diagrams, jitter decomposition, serial bus compliance analysis
Tektronix
AWG7102
10 GS/s arbitrary waveform generator — receiver (RX) tolerance testing with stressed signals and injected jitter
Tektronix
TDS8000B + 80E04 · 80A05
Sampling oscilloscope — impedance and transmission-line characterisation on a 20 GHz TDR module, plus 10G-class clock-recovery eye analysis
RF · Spectrum
RF & spectrum
Clock harmonics and radiated components are checked while the design is still on the bench.
Hewlett-Packard
HP 8566B
22 GHz spectrum analyser — RF spectrum, clock harmonics, pre-compliance EMI checks
Device-level
Device-level characterisation
Measurement starts at the device, not the board — the starting point for component screening and failure analysis.
Hewlett-Packard
HP 4145B
Semiconductor parameter analyser — I-V characterisation of transistors and diodes
Keysight
E4980AL
Precision LCR meter — impedance and C-V characterisation of passives and semiconductors
