5+1 questions about the temperature cycling test

The reliability of printed circuit boards is influenced by many factors. In the automotive, aerospace or even industrial sectors, the ambient temperatures of printed circuit boards can vary between -40° and +180°Celcius. In order to be able to determine how reliably electronic assemblies perform under these conditions, printed circuit boards can be subjected to a

SIR test according to IPC

High humidity, temperature fluctuations or even a combination of both: printed circuit boards are often exposed to unfavorable environmental conditions that have a negative impact on the reliability of electronic assemblies. A suitable method to be able to evaluate the resistance of the components under such adverse conditions is the SIR test according to IPC.
