Splet01. jul. 2024 · Further, the potting compound should also have a low CTE (Coefficient of Thermal Expansion) so that the effects of thermal cycling do not cause mechanical stress on the components or PCB, which may have a different CTE. A certain softness in the cured potting material also mitigates against such thermally-induced mechanical stresses. SpletHigh thermal stress will cause the PCB to deform and lead to severe problems in circuit operation, reliability, and longevity. The Importance of Thermal Stress Analysis in …
