According to reports, Apple plans to launch a new periscope lens on the iPhone 15 Pro model, which may further drive the development of camera module reduction and thinning technology, and the “periscope camera” is expected to return to the highlight moment.
Periscope camera
PERISCOPE CAMERA
For smartphones to achieve high-definition long-range shooting, traditional telephoto lenses achieve “optical zoom” through dual and multi-cameras.
Therefore, the “periscope camera” came into being.
The “periscope camera” of the mobile phone draws on the principle of the periscope, and arranges the cameras originally placed vertically in the mobile phone horizontally, and uses the internal space of the mobile phone and prism refraction to realize the optical path transformation, so that the lens with a longer focal length can be placed in a “folded” way. Into the mobile phone, avoiding the problem of abnormally obvious thickening of the body caused by the zoom lens.
Periscope camera gets cold
PERISCOPE CAMERA IS COOL
In the high-pixel era, the “periscope camera” is rapidly rising. In 2021, it will be the highlight of the periscope camera on the mobile phone, but in 2022, its popularity will drop rapidly.
“Periscope camera” belongs to optical innovation technology, which is still in the stage of continuous research and development and innovation. Compared with ordinary telephoto cameras, it has a more complex structure. Therefore, multiple links such as product yield and testing lead to higher costs.
In addition, compared with the traditional telephoto lens, although the “periscope camera” greatly reduces the thickness of the lens module. However, under the current trend of “light and thin” mobile phones, each device is robbing the limited space of mobile phones, and the “periscope camera” has been left out because of the thickness of the rear lens module.
Module thinning is the way out
MODULE THINNING IS THE WAY OUT
It is reported that the “periscope telephoto lens” that Apple’s iPhone 15 Pro and Pro Max will be equipped with will apply Jahwa Electronics’ OIS “foldable zoom technology patented technology”.
The technology will allow periscope camera systems to use prisms to fold light into the image sensor, mixing the light to create a smaller, thinner camera module that increases the iPhone’s optical zoom range.
The development of the “periscope camera” module thinning process means that the packaging industry will usher in new challenges.
internal components
The mobile phone camera module is composed of image processing chip, lens, sensor, focus motor, filter, PCB board, FPC, holder and other components. To assemble these increasingly miniaturized and special-shaped components together, not only a higher level of packaging technology is required, but also advanced packaging equipment is an important guarantee for improving product yield, which is conducive to reducing product cost and price.
At present, when smart terminals generally pursue ultra-thin, the camera module packaging technology is mainly based on “COB packaging”, especially in reducing the thickness of the camera module.
COB is a bare chip package. When the sensor chip is thinned, the force control of the chip pick-up nozzle of the chip mounter is relatively high during the placement process.
In addition, the camera module packaging requires multiple processes to combine different components. Under the limited space, precise control of the position and height of each component during the combination process is the key to ensuring the thinning process of the “periscope camera” module.
Guoao high-precision linear rotary motor is suitable for various SMT high-speed placement equipment, escorting the precise bonding of image sensors and optical components, improving the mounting yield of camera modules, and is an important supply of components for various packaging and testing equipment manufacturers. business.
Programmable high energy control to reduce loss
The Guoao linear rotary motor has the function of “soft landing”, which can realize stable force control within ±1g, and supports the programmed settings of speed, acceleration and force control, so that the placement head can touch the surface of the chip with very precise pressure , reduce the loss;
The motor supports the programmed setting of speed, acceleration and force control. Customers can set parameters according to the actual needs of the project, and can provide customized services according to the structure and characteristics of components.
High-precision alignment and placement to ensure yield
Micron-level position feedback, accurate data acquisition, ±0.01N force control accuracy, ±2μm linear repeatability, ±0.01°rotation repeatability, radial deflection less than 10μm, encoder resolution standard 1μm, can run at high speed The output is still stable, improving yield and reliability.
“Z+R” axis integrated design, improve speed
The innovative dual-axis integrated solution combines the traditional “servo motor + ball screw” into one, solves the Z-axis self-weight load problem, completes components Pick & Place, placement and other actions at high speed and accuracy, and the thrust curve is smooth , Peak thrust 8-50N, effective stroke 10-50mm, ultra-high cycle life, and efficient production.
Small size, light weight, can be combined with motors
The weight of the linear rotary motor LRS2015 is only 605g, and the lightweight body weight greatly reduces the impact of the load caused by the high-speed movement of the equipment. The thickness of the motor is only 20mm, and multiple sets of motors can be installed side by side in the limited internal space of the equipment, reducing the reciprocating movement process of chip mounting and improving the mounting efficiency of the equipment.
