Exposure of electronic components to dust, dirt, and steam causes negative effects on products. These negative effects can manifest as corrosion, short circuits, or performance problems. In order to prevent these results, leak tests of electronic products should be performed. In applications where it is not possible to pressurize electronic products and the internal volume, the external volume of the product must be pressurized to perform the leak test using the pressure decay method. IP67, IP68, and hermetic properties tests can be done by using EP60- IP standards leak test apparatus. Working with BT4000 Series devices, the product is fast, reportable, and precise.
