Abstract
An inspection method for inspecting the water resistance of an electronic device is provided, including providing a vacuum generator, using the vacuum generator to pump air out of the electronic device, stopping the pumping of air out of the electronic device when the air pressure in the electronic device is less than a predetermined pressure value, measuring the air pressure in the electronic device as a first pressure value after the pumping of air out of the electronic device has been stopped for a predetermined time, calculating the pressure difference D by subtracting a second pressure value from the predetermined pressure value, calculating the pressure difference d by subtracting the second pressure value from the first pressure value, and determining whether the electronic device is waterproof or not according to the pressure differences D and d.
