本月初发布iPhone7和iPhone7Plus时，手机的摄像头获得了大幅升级，正式宣布跨入双摄像头新时代。 Guide: When the iPhone 7 and iPhone 7 Plus were released earlier this month, the camera of the mobile phone was significantly upgraded, and it officially announced that it had entered a new era of dual cameras. The rise of laser soldering has undoubtedly laid a solid and solid processing pillar for the development of the dual camera module. The laser spray soldering system requires no tool contact during the process of welding the dual camera of the mobile phone, avoiding the contact between the tool and the device surface and causing the device surface Damage, higher processing accuracy, is a new type of microelectronic packaging and interconnection technology, which can perfectly assist the development of dual camera modules and achieve dual camera module welding.
Apple claims that the iPhone 7 camera's zoom capability has been improved to support wide color gamut shooting, and the iPhone 7 Plus also uses a dual-lens design with a wide-angle and telephoto lens. The dual camera is undoubtedly the most obvious highlight of the iPhone 7 in addition to the new color scheme. one. Phil Schiller, Apple ’s senior vice president of global marketing, introduced the iPhone 7 camera: "We won't say that you can throw a SLR camera, but we can say that this is the best iPhone camera and the best smartphone camera." .
The specific specifications are as follows:
iPhone7: single 12-megapixel camera, F1.8 aperture, up to 5x digital zoom;
iPhone 7 Plus: 12-megapixel wide-angle lens + 12-megapixel telephoto lens with apertures of F1.8 and F2.8, supporting up to 2x optical zoom and 10x digital zoom;
All support Optical Image Stabilization (OIS), six-mirror lens, 4-LED True Tone flash, wide color gamut photos and Live Photos, Focus Pixels autofocus, Focus Pixels light point focus;
Video shooting supports 4k / 30fps, 1080p / 60fps, 720p / 30fps standard video and 1080p / 120fps, 720p / 240fps slow motion video, all support optical image stabilization, iPhone 7 Plus also supports 2x optical zoom, 6x digital zoom .
It is worth mentioning that the Apple iPhone 7 Plus dual camera also records the direction of the optical information while recording the optical information. By evaluating the position change of the focus plane, the 3D depth calculation of the scene is realized. For the first time, the hardware-level light field camera technology was brought to the mobile phone. It can be said that it is the second generation of dual-cameras that support the "photograph first and then focus function" from the hardware level.
In addition, the new ISP image signal processor has doubled the processing power compared to the previous version. Supports machine learning technology to detect targets, set exposure, focus, and white balance. This can be done in 25 milliseconds, which is 60% faster than before.
The iPhone 7 Plus brings a depth of field effect comparable to that of a DSLR, which is much more similar to the depth of field effect of some low-end dual-cameras than PS.
For camera module manufacturers, the development of dual cameras has brought them new development opportunities and also brought relatively large challenges, which may break the original competition pattern of the industry. Camera module companies need to share another piece of "cake" in the smart terminal market. They also need to work hard to make the camera module less, faster and faster. Only in this way can they serve as the "eyes" of smart products, so that smart products can create better dreams for life and meet more needs.
The realization of the function of the dual camera module requires the structure of the original camera module to be changed, more compact, and the components more dense. It continues to challenge the existing processing and manufacturing processes. Traditional soldering iron has been unable to overcome the dual camera module. Difficulties in welding, the increasingly compact lead pitch makes the welding head unable to perform normal welding, and the yield is very low.
The rise of laser soldering has undoubtedly laid a solid and solid processing pillar for the development of dual camera modules. Wuhan Boliant laser spray soldering system does not require tool contact during the welding of dual cameras for mobile phones, avoiding the contact between tools and the surface of the device It causes damage to the surface of the device and has higher processing accuracy. It is a new type of microelectronic packaging and interconnection technology that can perfectly assist the development of dual camera modules and achieve dual camera module welding.
The laser spray soldering system adopts a multi-axis intelligent working platform, equipped with a synchronous CCD positioning and monitoring system, which can effectively guarantee the welding accuracy and yield. Adopting solder ball spray welding, high welding accuracy and reliable quality. 99.8% no virtual soldering through slicing experiments. Some are very sensitive to temperature or the welding area of the flexible board is connected, which can effectively guarantee the welding precision and high quality solder joints. The application of solder balls The range is 350um ~ 760um. Using universal clamping equipment, product replacement is easy. Wuhan Boliante RUIZE laser spray soldering system has the following characteristics:
7-axis intelligent working platform, equipped with synchronous CCD positioning and monitoring system, can effectively guarantee welding accuracy and yield.
Using solder ball spray soldering, the welding accuracy is very high. For some soldering areas that are very sensitive to the temperature of traditional wave soldering and reflow soldering, the "laser spray soldering system" can effectively guarantee the welding precision and the amount of solder can be controlled.
The universal clamping device is used to make the product easy to replace, without welding residue, and free of cleaning.
CCD positioning system, for welding electronic products with high precision requirements, the advantages of this equipment are prominent.
During processing, the laser does not make any contact with the welding object, so no mechanical stress is generated, which greatly weakens the thermal effect.
High efficiency and fast speed, the soldering time of a single solder ball is within 0.3s.
No additional flux or additional tools required.
Lead-free solders such as SnAg, SnAgCu, AuSn, InSn, SnBi provide support.
On-line robot programming processing, has provided online docking station mechanical interface to complete the production line docking.
The 2D image after welding can be used to check the welding status of the joint.
