Mobile phone lens module assembly process

1. Mobile phone lens module assembly process

First start to make a mobile phone, to make a schedule in advance, this schedule from the discussion of what kind of mobile phone to the final mass production of mobile phone. PE — — — — — a common process PDR – photo – the PEL – POR – EVT — — — — — DVT — — — — — – DVT123 — — — — — — — — PVT — — — — — — — OKSHIP, slowly in the process of the mobile phone from pieces of components are assembled into a whole, The software has modules that fill the whole system. These components are also produced by various device factories through different production plans and sent to the assembly plant to form the motherboard after patch assembly and so on, and then form the mobile phone after various factory tests. Before this PCL, we will confirm the suppliers of various devices such as screen, battery, module and so on, and get the price and inventory of these devices to support the needs of this mobile phone. Here, we have to mention our camera module. About the camera module, there are various parts (such as lens, sensor, motor, motor, etc.). Bases, etc.) These will be mentioned in a later section.

About the camera module, we first want to give you a simple idea. The working principle of A camera: the scene is projected to the surface of the image sensor through the lens to generate optical images, and then converted into electrical signals, through A/D (analog-to-digital conversion) into digital image signals, processed in the digital signal processing (DSP), and displayed by the DISPLAY device. After understanding this concept, it is not difficult to find that if we want to make a mobile phone, we must ensure that all components of this mobile phone are qualified, and whether these camera devices are qualified is confirmed by the module factory. The module factory takes the devices from sensor factory, lens factory, motor and other manufacturers to the production line for production. Ensure that the camera module formed by the combination of these devices is qualified. Originally, the lens and sensor factories have their own qualification standards, some manufacturers may be mixed, and some different batches of modules on the production line have various deviations, which will cause some devices to be unqualified. And we want to make mobile phones to ensure that the use of each mobile phone must be foolproof, and the mobile phone factory can not have no manufacturers to send people to supervise their production process, so the agreement with the module factory is commonly known as, the mobile phone factory will develop relatively strict testing requirements, and the module factory to ensure that each module must meet the scope of demand, and unqualified modules are defective products. So it's a game between module quality and cost.

As for the module factory, due to work reasons, I do not know much, but I have roughly found some information. There are more than 400 module factories, more than 100 lens factories, more than 60 VCM motor manufacturers, more than 150 FPC manufacturers, and about 2,000 accessories plastic materials and other enterprises around the country. In order to be responsible for themselves, general mobile phone manufacturers will find some capable manufacturers to cooperate, on the one hand to ensure the quality of their products, on the other hand to ensure the integrity of their supplier ecological chain. About what are these manufacturers, you can find some on the Internet, and from my work for three years, the project used modules are Shun Yu, Ou Fei Guang, Qiu Tai, Baoguang and other manufacturers. The sensor manufacturers I came into contact with are generally Sony, Samsung and OV, and the lens manufacturers I came into contact with are not many. Because of work reasons, the chip types and spec documents of these things are not convenient to disclose, if you are engaged in this work, the general company will provide.

You can't share your phone.

iOS mobile phone system and Android mobile phone system is not the same system, can not be shared data, so you can not share video operations.

3. What does a phone lens module mean

The composition structure of the mobile phone camera is mainly composed of lens group, infrared filter, voice coil, image sensor and module package. Image sensor is divided into CCD and CMOS two kinds, in the mobile phone camera, widely used is CMOS image sensor, CMOS integration is high, that is, small size, very adapt to the needs of the mobile phone camera module, is an indispensable part of the mobile phone camera.

4. Mobile phone lens assembly process

The hardware of the mobile phone is similar to that of the computer accessories, and the assembled mobile phone has the following accessories:

Display screen

Touch screen

Outer frame

Rear cover

Front and rear cameras (need to configure several more if equipped)

Various buttons, such as volume button, power button, etc

Peripheral connectors, including charging connector interface, headphone connector interface, mobile phone card connection port is naturally indispensable

Of course, the most important thing is the motherboard, and you have to prepare a battery that is a mobile phone battery

5. Picture of the assembly process of mobile phone lens module

Mobile phone camera module voice coil motor adhesive technology 80 degrees 5 minutes fast drying type has the following two types:

1, single-liquid epoxy resin follow-up agent for low-temperature hardening single-liquid epoxy resin. The resin has the characteristics of good toughness, low stress and resistance to hot and cold shock. This product has good flexibility and can join two materials with very different thermal expansion coefficients. The resin has good fatigue resistance and crack resistance, and can meet the requirements of vibration. The resin can provide good adhesion on many plastic and metal materials, and can be used between micro cameras and voice coil motors.

2, single-liquid epoxy resin adhesive is a single-liquid epoxy resin adhesive developed for electronic components. The resin is suitable for industrial applications with long operating times. This product has good adhesion and high hardness after FPV hardening, and has good resistance to fats, chemicals and solvents. This product is a low temperature hardening resin, suitable for use between various materials. The resin has excellent durability, has passed many different environmental tests, and is suitable for the assembly of VCM and C-MOS and the follow-up of thermal components.
