Reliability testing services

Programs that improve time to insight and reduce field failure risk.

HALT Testing

Expose design weaknesses with step stress thermal and multi axis random vibration. Determine operating and destruct limits.

Temperature & Humidity Testing

Detect latent manufacturing defects through thermal cycling and simulate real-world operating conditions.

RDT

Reliability Demonstration Testing (RDT)
Prove reliability targets with statistically valid plans.
Set sample size, stress profile, and accept criteria to demonstrate X% reliability at Y% confidence.

Temperature Cycling

Cycle products between hot and cold extremes to find solder joint, material and assembly weaknesses before they reach the field.

Thermal Shock

Hit products with rapid swings between hot and cold to expose cracks, delamination and seal failures.

IR Thermal Characterization

Find hot spots fast and shorten fault Isolation with high resolution thermography.

How it works

A clear path from stress to insight

Plan

Define goals, test conditions, and schedules. Align on risks and success criteria before beginning HALT or HASS reliability testing.

Design

Design or validate fixtures. Set thermal and vibration profiles with proper sensing to prepare for accelerated stress testing.

Run HALT or HASS

Push prototypes to the limits. Observe failure modes, capture data in real time, and uncover design weaknesses early.

Analyze

Identify root causes with photos, charts, and detailed reporting from HALT and HASS sessions. Recommend corrective actions to improve long-term product reliability.

Screen and scale

Translate HALT findings into a production HASS screen. Protect yield and scale confidently with proven reliability testing.
