PCB supplier china：What is Interfacial Stress in PCBs
As PCB supplier china knows that, Interfacial stress is the stress that is generated as a result of soldering two different metals together. Different metals have different CTEs (coefficient of thermal expansion) and thus expand and contract by different amounts as the temperature changes. When two different metals are soldered together, changes in temperature can cause one metal to expand more than the other. Stress caused due to this phenomenon is called Interfacial Stress.

An example of this would be joining the leads of a component to a copper pad on a PCB board. The component leads can be a different material from the copper pads. The component leads are soldered onto the copper pads to form an electrical connection. An increase in temperature can cause both metals to expand by different amounts and thus interfacial stress can cause the solder joint to crack and result in a bad connection.
