PCB electronic control board automated precision assembly

The robot grabs PCB boards, wiring terminals, heat dissipation shells, servo crimps terminals, and micro-tightens the module to lock the shell bolts. The ion blower eliminates static electricity in real time to prevent electrostatic breakdown of the chip; it visually detects missing solder components and terminal skew defects, and automatically diverts defective products.

Long-term online power-on aging test

The controller is continuously powered on for 2 to 12 hours, and the system collects operating current, signal output, and chip temperature data every 30 seconds to simulate the continuous operating conditions of the vehicle, screen out early failure parts of capacitors and chips, and significantly reduce the after-sales failure rate of the controller.

High and low temperature extreme working conditions bus simulation test

The workpiece is sent into the temperature-changing cavity to simulate the low-temperature winter and high-temperature vehicle environments in summer. Vehicle control instructions are issued through the CAN/LIN bus to verify the signal transmission and logic control stability of the controller in hot and cold environments, and to intercept temperature drift failure faults in advance.

Full-dimensional verification of electronic control functions

Completely simulates various control signals of the entire vehicle, detects the controller output drive, feedback signals, and fault diagnosis functions, covering the full logic of air conditioning, heating and cooling, battery thermal management, and door and window control to ensure that there are no abnormal functions after installation.

Digital traceability of electronic component batches

Each controller is bound with a QR code, which is associated with upstream purchasing batches of PCB boards, chips, and wiring harnesses. Assembly, aging, and high and low temperature test data are permanently stored. In the event of batch electronic control failures, component suppliers can be quickly located to support quality claims and process rectification.

Commercial value: after-sales faults such as hot and cold failures of vehicle controllers and communication failures have been reduced by 94%, and the loss of electrostatic breakdown components has been completely eliminated; the production line has been invested in modular phases to relieve customers' early equipment financial pressure and adapt to the iteration of new electronic control products and rapid production changes.
