Sharing of mobile phone camera waterproof testing/air tightness testing methods
手机作为通讯消费产品，已成为了人们日常生活的必须品，伴随着光电及科学技术的发展，手机在原有通讯功能的基础上又新增多种功能，例如数码照相、看电视电影、QQ/微信随时随地聊天等功能，手机摄像头是手机上能够进行拍摄图片和摄像功能的主要部件，也是手机的附加功能，随着手机行业的不断发展，手机摄像功能已经成为手机用户最为关注的手机性能之一。人们不仅要求手机摄像头像素高，拍照清晰，同时希望手机摄像头具有防水功能，即使在潮湿的环境中甚至靠近水域的地方，也可以无所畏惧的使用手机拍照摄像。这样手机生产商就需要在生产手机的时候对手机壳上的摄像头进行防水测试/Air tightness testing。

Although existing mobile phone cameras have various functions, they are generally not waterproof.The camera is scratched or stained with fingerprints and dust due to lack of protection, which greatly affects the shooting effect. If water enters the camera, the camera will be very unclear.
I remember a friend who had a child less than one year old at home who would explore everything he saw with his mouth.At that time, I used my friend’s mobile phone camera as a toy and licked it with my mouth. Later, saliva entered the camera, causing the camera to be unable to shoot normally. Now many mobile phone manufacturers have launched waterproof mobile phones, and the cameras on the mobile phones are also waterproof. Therefore, each mobile phone camera needs to be tested for waterproofing or IP67.This time, Hairis Technology will share with you the air tightness testing method and testing steps of mobile phone cameras.
As can be seen from the appearance of the product, the mobile phone camera is on the back of the phone case and the area is relatively small. We can directly seal the surrounding area of the camera and directly inflate this area for inspection.This method of direct inflation is called direct testing. If a mold needs to be made for the product, the method of testing the sealing property of the product by inflating the mold is called indirect testing.The Hairis air tightness detector has two pressure options, positive and negative, and 8 test modes, which can be selected individually or in combination, and can meet the needs of most manufacturers for air tightness testing.

According to the customer's testing requirements, the waterproof level of this mobile phone camera is IP67, and we use a pressure of 12KPA for testing.Because the products being tested are relatively small, they can be tested quickly.The air intake time is 3s, the voltage stabilization time is 3s, and the test time is 3s. So the total time is 9s, and the test is completed in 9s. The Hairis air tightness detector can complete the test quickly and accurately.

Advantages of using Hairis air tightness testing instruments:
Figure: Tester
1. High-sensitivity pressure sensing and adjustment unit, combined with advanced differential pressure software algorithm, the minimum resolution can reach 0.1Pa. This algorithm has obtained a national patent
2. Patented technology independently developed by Hairuis."IVT pneumatic sealing valve island", greatly improving the test accuracy, ensuring the stability of the instrument, and the inflation speed is also greatly improved.
3. Multiple test functions: The instrument integrates two pressure forms, positive and negative, and 8 test methods: two pressure forms and five test methods can be programmed into more than 20 test functions.
4. It has more than 200 groups of subroutines. Each group of subroutines can be programmed independently and can be selected or combined to meet various complex testing requirements.
5. Full-touch large-screen intelligent operating system, graphical UI design based on the detection process, the operation interface is simple and clear, easy to teach and learn
6. A variety of pressure adjustment components and ranges are optional, with a wide air pressure range (-80KPA&-1MPa) optional.Optional electronic pressure regulating valve can realize multiple sets of pressure sequential testing
7. Multiple communication interfaces: built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supporting multiple communication protocols
8. Optional barcode scanning function and printer are available to facilitate product data management and quality traceability. The instrument history record can reach up to 200,000 items and can be exported to the computer in batches.
9. The standard volume identification function can automatically identify the volume of the sample to be tested, and measure and judge the leakage rate in a volumetric manner.
10. Ultra-high stability and ease of use have passed the rigorous test of the market.
