Application and breakthrough of constant temperature laser soldering system on camera module
Nowadays, electronic devices have been developed in the direction of miniaturization, high integration, and multi-function, and the distance between devices and devices, devices and pads is getting smaller and smaller. As well as the large-scale mass production, the improvement of product production efficiency and yield requirements, the necessity of laser as a welding heat source is increasingly reflected.
At present, most domestic camera module factories still use traditional soldering and hot-welding welding processes. Because soldering and hot-welding are contact-welding methods, and due to the small limitations of the camera module solder joints, The precision of the welding head and fixture is extremely high. Efficiency and yield can not meet the demand for timely large orders.
Then the way of using laser to heat source welding in this field is ready. Ruize Technology has successfully developed a professional laser welding system in cooperation with a famous camera module manufacturer to solve the traditional welding method. The problem has greatly improved the welding efficiency and the yield rate, and effectively complied with the development trend of the camera welding process to improve the competitiveness of the enterprise.
The constant temperature laser soldering system will be a revolutionary breakthrough and success story in the field of camera modules. As shown below
The constant temperature laser soldering system delivers superior performance and reliability through a number of innovative design and integration technologies. From a technical point of view, the device uses the most stable semiconductor laser as the energy source to ensure the high stability of the laser energy; through the latest optical technology, the laser, CCD, temperature measurement, and indicator light are coaxial at four points, perfect It solves the problem of four points of solder joints, guiding light, imaging points and solder joints to avoid complicated debugging, which is more suitable for precision welding of highly precise microelectronics. The unique feature positioning method ensures the mass production welding yield of precision microelectronics. The fully air-cooled design makes the machine compact, compact, and flexible, making it suitable for processing on large production lines.
The solder effect diagram is as follows:
The traditional method is 12S/piece welding, and the laser welding efficiency is 2S/piece. Due to the characteristics of constant temperature laser welding, the temperature of the soldering point can be kept constant, so that welding can be guaranteed without damaging the camera module. .
In summary: from the application of the constant temperature laser soldering system in the field of camera modules, it can be clearly seen that the traditional process is broken, and in the production line that is easy to realize laser automation, the production efficiency is greatly improved, because the characteristics of the laser solder are adopted. Non-contact welding method, the spot can be adjusted to 0.4mm, which will not cause stress and heat on the heat sensitive parts around the solder joint. Therefore, the quality will be greatly improved.
