Description

  The present invention relates to a technique for inspecting and determining waterproof performance in electronic devices such as a mobile phone, PHS, and digital camera having waterproof properties.

  There is a growing need for waterproofing of electronic devices such as mobile phones, PHSs, digital cameras, etc., which are frequently used outdoors, and for this reason, there are increasing cases of waterproofing inspections at shipping inspections. As a waterproof test method, measure the amount of water entering the device under test by immersing the device under test in water, or air outside the device when a certain amount of air is added to the device under test. There is a method for determining the presence or absence of leakage into the device. However, in this method, there is a risk that electronic equipment may fail or performance may deteriorate due to the inflow of water into the device at the time of inspection.

  Patent Document 1 proposes a means for solving such a problem and making it possible to perform an air tightness test of a device without immersing the device under test in water.

  In the airtight test method described in Patent Document 1, an external pressure is applied to the device under test in a state where the inside of the device under test communicates with the atmosphere. A change in atmospheric pressure caused by a difference in the amount of air flowing into the test equipment is measured, and a normal product and an abnormal product are discriminated by determining the airtightness of the device under test based on the measurement result.

  According to the airtight test method described in Patent Document 1, it is possible to evaluate the airtight test of a device that requires airtightness in a relatively short time, to reduce the cost of the evaluation work, and to immerse the device in water. Therefore, it is possible to eliminate the adverse effects of the airtight test, such as preventing the performance deterioration of the equipment, and to improve the quality. However, in this airtight test method, the device under test is installed in the airtight room in the airtight room. The connection work with the nozzles and the like must be performed, and since only one unit can be inspected, the inspection is inefficient and cannot be said to be an inspection method suitable for mass production.

  That is, in the invention described in Patent Document 1, after inserting the device under test into the airtight chamber, first, the inside of the device under test is connected to the first electromagnetic valve and the first mano staging via the nozzle, hose, and three-way joint. In a communicated state, the compressed air is introduced into the airtight chamber to increase the pressure in the airtight chamber to a required pressure, and the device under test is compressed and deformed by the external pressure. The first electromagnetic valve was released into the atmosphere, and then, after a set time sufficient to complete the compression deformation of the device under test, the first electromagnetic valve was closed and the inside of the device under test was sealed. In this state, if there is air leakage from the inside of the hermetic chamber to the inside of the device under test, the internal pressure of the device under test rises. Therefore, the change in the internal pressure is detected by the mano staging and the device under test Configuration to determine the tightness of the equipment You have me.

  Therefore, in order to determine the airtightness of a plurality of devices under test at the same time in this airtight chamber, the individual first solenoid valve, the first mano stage gauge are individually connected via individual nozzles, hoses and three-way joints.
