Choosing the Right Leak Testing Method for My Electronics Application.
There are several air leak testing methods used in electronics manufacturing. Each method has its advantages and limitations, which can make selecting the correct method a daunting task. Thankfully, our experts are here to make your transition to air leak testing effortless, providing the type of knowledgeable support and guidance you’ve come to expect from LeakMaster.
The three most widely used Air Leak Testing Technologies used in electronic applications are Pressure Decay, Differential Pressure and Metered Volume Chamber Testing (for testing sealed electronic components).
The Defender Pressure or Vacuum Decay leak tester is our most widely used instrument in the electronics industry and considered an outstanding value due to its low cost, test efficiency and built-in data collection feature.
The pressure decay method typically involves pressurizing the consumer product and monitoring for excessive drop in pressure over a specific Test period. User-defined decay limits are referenced to pass or fail the product being tested.
Differential Pressure Decay
The Guardian or Stealth Differential Pressure Decay leak testers are used to detect smaller leak rates in the 0.1 sccm to 100 sccm leak rate range. Differential Pressure is a relatively simple test with excellent resolution. It’s the preferred method whenever the leak rate is too low for standard pressure decay.With this procedure the difference in pressure between a master reservoir and a production part is compared to determine the leak rate. The full scale of the DP transducer is much smaller, providing higher pressure loss resolution than standard Pressure Decay or Mass Flow to measure smaller amounts of decay in faulty electronics assemblies.
Metered Volume/Chamber Leak Testing
Metered volume is a technique frequently used in IP67 testing or when leak testing a sealed component (completely sealed part, without a port or passageway to pressurize or pull a vacuum inside the test part). With metered volume leak testing, the electronic device is sealed in a leak free chamber. At the start of the Test, the leak tester displaces a specific air volume and pressure into the chamber. If the electronic device in the chamber is leak free, the pressure will remain steady in the chamber. If the device is leaking, the pressure will fall in the chamber, indicating air is leaking into the test component (leak).LeakMaster serves a diverse range of electronics industries with professional leak testing solutions and customer first collaboration. Through experience and listening to our customers, we provide application specific leak testing solutions to reduce product liability, improve test accuracy, and enhance efficiency.
