As an image input device, camera is widely used in camera shooting, mobile video, security monitoring and other fields. The quality of the camera has a great relationship with the camera module. With the continuous progress of science and technology, the technology of the camera module is also improving.All kinds of mobile phones, computers and other intelligent devices will inevitably come into contact with water, dust and other harmful acid-base pollutants in the living environment or natural environmentTherefore, it is inevitable that the mobile phone lens group will get water.
Product to be tested: waterproof and breathable film for lens group
The lens group is connected to the inside of the mobile phone, and water will cause damage to the inside of the mobile phone,Waterproof and breathable film for lens groupGood solution to the problem of waterproof lens group, in the prevention of water at the same time, it can provide excellent protection in the process of mobile phone operation, to prevent the invasion of external moisture and dust.
Details of real water detection for waterproof and breathable film of lens group
Waterproof and breathable membrane protectionLens groupNot affected by water, but also has a certain role in dust and ventilation。 The customer is preparing forWaterproof and breathable film for lens groupdoWaterproof performance testAndIt is required not to leak, but also to be breathable.
True water test equipment for lens group
Hiris technology uses the following equipment and methods for the product:
Equipment used: HarrisHWTrue water tester
Detection method: set an upper and lower pumping limit. The upper and lower pumping limits are set to detect whether there is a product. If there is no product, the instrument will not start. What is the test pressure used for the waterproof and breathable film of this camera17KPA, the leakage value cannot be greater than20pa，Otherwise, the waterproof and breathable membrane will leak.
utilizeHarrisHWThe real water tester can accurately screen out the waterproof and breathable membrane that will leak.
Testing equipment for waterproof and breathable film of lens module
HarrisHWTrue water testerIt is applied to the sealing test of waterproof and breathable film of lens group. It can be detected quickly（5-7S）The resolution is up to1Pa/sIn order to adapt to the requirements of high quality and help customers achieve the purpose of cost control, Harris develops more process techniques and design concepts.
