Electronic products must function reliably under a wide variety of conditions. Temperature-related pressure fluctuations can cause a vacuum to build up inside. Cyclical heating and cooling stresses the seals and can lead to leaks. To reduce this risk, pressure compensation elements are used for ventilation, which enable pressure compensation while simultaneously protecting against oil, water and particles. The specific properties of pressure compensation elements and the special features of leak testing of products with pressure compensation elements are dealt with in a practical manner.
