Control module
As the core of robot intelligent decision-making and motion control, the AI ​​robot control module (CU) integrates high-computing AI chips, power devices and high-speed communication units. It generates a large amount of heat during the continuous operation process and faces long-term challenges in vibration, dust and hot and humid environments. MCOTI provides overall material solutions to achieve efficient thermal conductivity, structural reinforcement and environmental protection, and comprehensively improve the reliability, stability and service life of the control module.

Improve component reliability with our innovative adhesive materials for solder joint reinforcement. We provide tailor-made solutions that support a variety of connection stabilization and optimization methods to help you ensure that semiconductor chips and other electronic devices maintain excellent performance throughout their life cycle. There are various methods for mechanical reinforcement of BGAs and other components, whether underfill, corner filling or corner fixing, each method has its own advantages and varies in terms of degree of reinforcement, amount of material, process speed, reworkability and CO2 emissions.

Underfill: It is the most reliable solution. Glue is dispensed on the side of the chip and the gaps between the solder balls are fully filled through capillary action;

Cornerfill: Dispensing glue at the four corners and partially filling the gaps between the solder balls can enhance the mechanical strength of the four corners of the chip/PCB;

Edgebond: only covers the four corners, and the dispensing height is greater than 50% of the chip body. It is suitable for large-sized chips, saving costs & can be repaired.
