1. Drone project
Cooperate with A company to develop and mass production of agricultural drone assistant, from 2019 development to batch stable production in 13 months, now stable supply sales have nearly 200 million.
2. Intelligent sensor device project
During the global business outbreak, the production capacity of contactless daily induction products cooperated with B company surged and the supply of materials was insufficient. Our company has been stationed in the factory for a long time to work with the terminal to select materials for trial production and timely promote the terminal to sell finished products. Annual sales reached 500 million.
3. Industrial air conditioning project
The hard requirement of industrial projects is that the material supply must be stable and the production of terminals needs to be guaranteed on a yearly basis. C company has been cooperating with us since 2016, and our supply projects have never been out of material, and we have been rated as high-quality supplier by the brand for 4 consecutive years.
4.High-Reliability PCBA for Robotic Control Systems
A leading robotics manufacturer required mission-critical PCBAs for their new industrial robotic arm, comprising:
Main Control Board: Xilinx Zynq UltraScale+ MPSoC platform
