LEAK RATE - VES
important to define how small the maximum acceptable leak rate is for a product; any component with a bigger leak rate should be classified as a reject or sent to a re-work station. A helium leak detection system is designed to give a measurement of the leak rate associated to a specific component, so that this can be classified as a
