Abstract

Overview - ISO 17841:2015 (thermal fatigue test for fine ceramics substrate)

ISO 17841:2015 specifies standardized test methods for determining the thermal fatigue properties of fine ceramic substrates (advanced/technical ceramics) used in power modules, electronic control units (ECUs) and similar devices. The standard defines specimen geometry, thermal cycling regimes, mechanical test methods (four‑point bending), measurement precision and reporting requirements to assess how ceramic substrates and metal‑ceramic assemblies resist repeated temperature changes.

Key technical topics and requirements

Test specimens: Composite specimens consist of a fine ceramic plate with metal plates joined to both faces. Standard ceramic dimensions: length 40.0 mm, width 10.0 ± 0.5 mm. Ceramic thicknesses listed from 0.20 mm to 1.50 mm; metal plate thicknesses from 0.125 mm to 0.6 mm. Minimum of 10 specimens per condition.
Thermal cycling / thermal fatigue:
- Defined combinations of low and high temperatures (e.g., low: −65 °C to +5 °C; high: +30 °C to +200 °C) with ±2 °C tolerances.
- Standard cycle counts: N = 0, 10, 100, 300, 1 000, 3 000 (other N allowed if reported).
- Standard exposure time: 30 min (adjustable for specimen heat capacity).
- Transfer time categories: **
