Camera module CCM and application glue introduction

1.Camera module packaging and glue points

2.Glue dots for camera

On the mobile phone camera module, there are more glue points, and the number of complicated ones is about 30;

At the same time, there are many materials to be bonded, and the scene is complex. There are various types of substrates for camera connection, such as LCP/ceramic/glass/PET/PC/PBT/PA/FR4, etc. Different substrates have great differences in glue bonding

3. Glue application point requirements and related glue:

Lens and mirror base fixing glue: barrel and Holder are fixed to prevent malfunction caused by focal length changes. Requirements:
1. Optical transparent glue with low shrinkage rate;
2. There must be glue in the gap between the lens and the motor parts;
3. Do not damage the quality of optical instruments and avoid stress on the glass lens; 4. Optical components must be fixed quickly after precise adjustment
5. The glue should not touch the end face of the lens or the voice coil motor. It is usually a low-temperature thermosetting glue with a relatively high viscosity.

Reinforcing sealant: on the one hand, it is used to connect the iron shell to increase the sealing, on the other hand, it can conduct current

VCM packaging glue: There are many glue points on the VCM motor, bonding the coil and the bracket. Magnets hold. Shrapnel fixation mainly plays the role of structural bonding
