In the AIoT & Robot Components Manufacturing field, the stability of intelligent robot component PCBs directly determines the success rate and safety margins of terminal devices. As the complexity and integration of humanoid robots, intelligent lawnmowers, and medical AI devices continue to increase, traditional consumer electronics-level PCB designs can no longer meet the long-term stability requirements under harsh operating conditions. A single failure often means mission failure, huge losses, or even personal injury. Therefore, building a PCB reliability assurance system covering the entire lifecycle has become an industry consensus.
Reliability design is not a post-hoc remedy, but begins with the top-level architecture. In the AI computing PCB design stage, a multi-dimensional evaluation of material principles, materials, processes, structures, electrical characteristics, failure modes, and mechanisms is required based on the application scenario. Taking an AI main control system as an example, the substrate used is S1000H, a material with excellent electrical properties, mechanical strength, and heat resistance. The board thickness is set at 1.6mm, employing a 6-layer structure design with a 10Z copper thickness to meet stringent requirements for current carrying capacity and signal transmission. Line width and spacing are both set at 6mm to ensure sufficient electrical isolation. For high-computing demands, such as a high-performance AI smart terminal controller based on the NVIDIA Jetson AGX Orin module, featuring a 1792-core GPU and AI computing power of up to 200 TOPS, its PCB layout must fully consider conductive passive heat dissipation design to ensure excellent heat dissipation capabilities.
For high-density interconnect requirements, HDI PCB and Flex PCB technologies are widely used. In the humanoid robot product matrix, rigid-flex PCBs, rigid-flex PCBs with buried vias, and rigid-flex PCBs with gold finger reinforcement are used for intelligent main control boards and joint drive boards to achieve 3D assembly and micro-packaging. The core control component, equivalent to the robot's "brain," employs a high-performance microprocessor or microcontroller, such as the STM32H723VGT6 chip, and features abundant interfaces for connecting other sensors, actuators, and expansion modules. Simultaneously, signal integrity control reduces signal interference and reflections through reasonable wiring design (such as differential pair wiring and impedance matching), ensuring stable signal transmission.
The stability of the manufacturing process is the physical foundation for PCB reliability. In the PCB fabrication stage, comprehensive and standardized process design guidelines, material selection and control systems, and quality evaluation systems are established, encompassing process design, material selection and control, process implementation, quality evaluation, and organizational management. This significantly improves the technical and organizational capabilities for process reliability, reducing the product's process failure rate. Process reliability covers key nodes such as component molding, reflow soldering, printing, testing, and depaneling.
To ensure manufacturing quality, the production system must be certified to ISO9001, IATF16949, and ISO13485, and operate 24/7. For PCBs used in intelligent robot components, the smallest package size can reach 0201 (0.6mm0.3mm) or even 01005 (0.3mm0.2mm), and the mounting accuracy of BGA, FCAA, POP, and other components must reach 0.5 pitch. During the PCB prototyping stage, component and product reliability testing is conducted using online SPI and 3D-AOI methods. High-reliability surface treatment processes, such as immersion gold, immersion tin, or OSP, are used to improve soldering reliability and corrosion resistance. For specialized fields such as Medical AI PCB design, even more stringent cleanliness and biocompatibility requirements must be met.
The verification phase is the last line of defense for reliability assurance. By analyzing the external environmental stress during product testing, we identify reliability-sensitive stresses during product use and provide customers with environmental reliability, mechanical reliability, and electrical reliability testing services (including component screening). Reliability testing equipment includes aging chambers, constant temperature and humidity chambers, thermal shock chambers, rapid temperature change chambers, salt spray chambers, vibration chambers, drop testers, CAF testers, insulation resistance testers, and withstand voltage testers.
Using failure mechanism analysis, testing, and mechanism verification, we identify the root cause (RCA) behind the failure and provide customers with PCB, component, PCBA, and product failure analysis services. We propose targeted rectification and preventative measures. For example, in the case of the intelligent lawnmower's main control system, the core board is equipped with a high-efficiency heatsink to effectively reduce the chip's temperature during operation. It uses the Horizon Solar X3 processor, supporting software-level frequency control to ensure the lawnmower's stability and control. For AI server PCB manufacturers, long MTBF (Mean Time Between Failures) is a key performance indicator, enabling the deployment of AI computing power for deep learning at the application level.
