Intelligent Camera Module Adhesive Solutions for Consumer Electronics
The number of camera modules used in consumer electronics devices continues to grow rapidly as electronic devices become more mobile and wearable. Market estimates forecast the global market for CCMs (compact camera modules) to be $31.5 billion in 2020, growing to $44.6 billion by 2024.
A camera module contains many different components integrated into a single unit. Due to space constraints, they can only be assembled together with adhesives. These components are made of many different materials and therefore require different adhesives to bond them. Depending on the specific bonding application, each adhesive has very specific performance targets.
Thanks to our outstanding innovation and advanced technology in the field of electronic adhesives, YASUDA's material scientists have developed and fully supplied adhesive solutions for camera modules for smart consumer electronics, including specialized adhesives for each component, adhesive bonding and curing technology. YASUDA's adhesives offer outstanding versatility to bond to many different materials, have high tensile strength, and withstand harsh environments.
I. Bracket Adhesives
Characteristics
UV curing
Shaded area cures at low temperatures.
Good adhesion to resin and LCP surfaces
Short dispensing cycle time for automatic integration
Low outgassing and low shrinkage
Good temperature stability and resistance to climate change
II. Infrared Filter Adhesives
Infrared filter lenses help remove infrared wavelengths of sunlight, filter diffraction, protect image sensors and prevent images from turning red. The lenses are fixed to the frame with an adhesive. Therefore, the adhesive needs to filter out more than 99% of the infrared radiation.
Features
Optimized camera modulus to ensure drop test reliability
Excellent adhesion to IR filters of various plastic and ceramic materials
Optimized flow characteristics and viscosity for easy adjustment of dispensing pins
Low-temperature cure helps avoid damage to optics and coatings.
Adhesive colors from clear to black, adjustable to customer requirements
Good temperature stability and resistance to climate change
Low outgassing
III. Camera Module Voice Coil Motor (VCM) Special Adhesive
Today, millions of smartphone cameras are equipped with autofocus (AF) and OIS optical stabilization technology based on the VCM platform. YASUDA's adhesives can hold parts extremely quickly and can cure blurred areas. This is a big advantage because VCM modules have many very small details and have surfaces that are as difficult to bond as LCP or PC.
Features
UV curing
Low-temperature curing
Very low outgassing without damage to lenses, filters, or sensors
Excellent bond strength on substrates and metals used in LCP and PC, etc.
Fast curing and high performance
Drop test resistance
Solvent-free composition
IV. Retainer Replacement
Due to limited space and the requirement to ensure that the lens allows the sensor to absorb the maximum amount of light, there must be no dirty adhesive on the smartphone camera lens. Therefore, a black adhesive will significantly improve effectiveness. In addition, these components are very sensitive to heat and therefore require an adhesive that can cure at low temperatures.
Properties
Low-temperature curing
High curing speed and high performance
Maximum cost reduction through optimized adhesive distribution
Very low volatile vapor, no effect on optical components
The adhesive is black, contributing to better light acquisition.
Good adhesion to a wide range of materials such as PC, ZEONEX, COC, CO
