Migration Test/Conductive Anodic Filament (CAF) Resistance Test, Highly Accelerated Stress Test Chemitox

[Migration Test / CAF Resistance Test]
・PCB and substrate material manufacturers
Insulation reliability evaluation and quality assurance for printed circuit boards and substrate materials.

As wiring continues to shrink, layer counts increase, and mounting density rises, the risk of insulation degradation due to ion migration and CAF is growing. This service is ideal for customers seeking to assess these latent insulation failure risks.

[HAST/PCT]
・Electronic component and semiconductor manufacturers
Reliability evaluation of semiconductor packages, electronic components, and sensors.
・PCB manufacturers
Durability evaluation of substrate materials and insulation structures under high-temperature, high-humidity conditions.
・Development engineers in automotive and industrial sectors
Lifetime evaluation and quality assurance for high-reliability products including EVs, ADAS systems, industrial equipment, and communications devices.

[Migration Test / CAF Resistance Test]
・Insulation reliability evaluation of PCBs
Voltage is applied continuously under high-temperature, high-humidity conditions to evaluate insulation degradation and ion migration.
・CAF evaluation of multilayer substrates
Assesses CAF (Conductive Anodic Filament) formation risk between through-holes and interlayer insulation regions to support long-term reliability improvement.
・Comparative evaluation after material or structural changes
Evaluates the impact on insulation reliability when changing substrate materials, resin, glass cloth specifications, or pattern design.

[HAST/PCT]
・Accelerated lifetime evaluation
Samples are exposed to elevated temperature, humidity, and pressure to accelerate degradation and enable rapid lifetime assessment.
・Combined testing with migration testing
Voltage application during HAST/PCT enables composite stress evaluation of insulating materials and electronic components.

HAST uses unsaturated pressurized steam to rapidly reproduce moisture absorption and degradation. PCT uses saturated steam (100%RH), inducing surface condensation, and is suited for verifying structural resistance to moisture ingress.

[Migration Test / CAF Resistance Test]
・Among the largest testing capacities in Japan
With over 700 migration tester channels, simultaneous evaluation of a large number of samples is possible.
・High-voltage capability up to 3,000 V
In addition to standard migration testing, insulation reliability evaluation under high-voltage conditions is also supported.
・Continuous micro-current monitoring
Continuous measurement of micro-currents enables tracking of not only breakdown events but also the progression of degradation over time.

[HAST/PCT]
・High acceleration performance
By combining elevated temperature and humidity with pressurized conditions, degradation phenomena that would otherwise require extended periods can be evaluated in a short timeframe.
・Voltage application capability
In combination with a migration tester, voltage application up to 1 kV and insulation resistance measurement are supported.
・Broad equipment lineup
Both single-chamber and dual-chamber units are available, enabling flexible accommodation of different test requirements and sample sizes.
