Nowadays, mobile phones are developing towards high integration, high precision, reliability, portability, and high automation. Therefore, higher technical requirements have been put forward for the production process of mobile phones. Of course, the dispensing process is used in various parts of the phone. Below, we will dissect the dispensing points and types of glue used in the camera module based on the glue usage situation.
The main components of the camera module are shown in the figure:
1. Flexible Board Cable (FBC),
2. Image Sensor/CMOS,
3. Holder,
4. Lens Set,
5. Substrate,
6. Voice coil motor (VCM),
7. Printed circuit boards (PCBs), etc.
The structure of the camera module is very fine, and there are multiple internal components that require dispensing technology. At the same time, it is also required that the base and the four corners of the filter be glued and the glue should not splash onto the filter and base,
The main areas where the camera module camera is glued include the following:
1. After adjusting the focal length of the LENS camera, it needs to be fixed with UV glue; Require UV adhesive to have low shrinkage and good optical transmittance
2. The camera sensor requires underfll bottom filling process; Fill the gaps in the solder area at the bottom of the chip, resulting in anti drop and anti vibration effects
3. The motor and Holder base need to be fixed with a strip of adhesive with a width of 0.2-0.3mm, using high-strength UV adhesive. Equipped with a fixed motor and base, while also providing dustproof function
4. The camera module and PCB are reinforced and bonded using low-temperature curing adhesive, which has the characteristics of rapid low-temperature curing, excellent weather resistance, electronic insulation characteristics, and strong impact resistance.
In summary, the types of glue used on cameras mainly include UV glue, bottom filling glue, low-temperature curing glue, etc. The dispensing work is achieved by accurately controlling the dispensing amount through automatic dispensing equipment. Provide dispensing technical support for achieving high-precision, high-quality, and high stability camera production.
