Huawei’s new Laser Autofocus sourcing for the Mate 60 Pro
Autofocus is indispensable in smartphone photography, and ultra-premium handsets rely on direct time-of-flight (dToF) “laser autofocus” modules to determine the distance to the scene, especially in low-light conditions.
Recently, the Huawei Mate 60 Pro shocked the world by producing an ultra-premium smartphone in spite of trade restrictions. To accomplish this, they were obligated to overhaul their supply chain. Among the changes, Huawei ended its reliance on STMicroelectronics “FlightSense” laser autofocus modules and opted instead for a solution from VisionICs.
This full reverse costing study has been conducted to provide insight into the technology, manufacturing cost and selling price of the VisionICs VI5300 1D dToF Laser Autofocus module in the Huawei Mate 60 Pro.
The module consists of a single-photon avalanche diode (SPAD)-based application specific integrated circuit (ASIC) that contains the dToF histogramming logic and driving logic for the 940 nm vertical cavity light-emitting laser (VCSEL). The design is analogous to that of the STMicroelectronics VL53L0 that it replaced.
A detailed physical analysis, including teardown, cross sectional analysis, circuit delayering, and scanning electron microscopy determines the component structures and technologies. This information is then used to calculate the costs of each production step to provide a detailed cost breakdown of the manufacturing process and estimate the final selling price of the module to Huawei.
We also include a comparison with the STMicroelectronics VL53L0 used in the preceding generations of the Mate/P series.
