Leak Detector

A leak detector is a type of test equipment used to detect and locate leaks in packaged semiconductor components. It operates by creating a pressure difference between the inside and outside of the package and then measuring any loss of pressure over time. The leak detector can be used to test packages for leaks in seals, bond wires, or any other potential sources of leakage. The results of the leak test can be used to identify faulty packages, which can then be repaired or replaced. The leak detector works by introducing a tracer gas into the package and then measuring the concentration of the gas inside the package to determine if there are any leaks. If the concentration of the tracer gas inside the package is found to be lower than expected, it indicates a leak in the package. Some common tracer gases used in leak detection include hydrogen, helium, and nitrogen.
