Cold plates are key components in liquid cooling systems, ensuring efficient heat dissipation and reliable system performance. To guarantee the quality of every component before assembly, the customer required a fully automated End-of-Line (EOL) testing solution capable of validating each part with maximum reliability.
The main challenge was to integrate multiple quality-control processes into a single automated cell. The solution had to perform structural integrity verification, high-sensitivity helium leak testing, dimensional and vision inspection, laser marking and complete traceability, while maintaining high production throughput and consistent testing conditions.
Gaindu developed a fully integrated EOL testing cell that automates the complete inspection process. Robotic handling transfers each Cold Plate through every testing station, while all process data is recorded and linked to a unique 2D Data Matrix code, ensuring full traceability and reliable quality control for every part.
OPERATIONS
Part Loading & Identification
Trays containing multiple Cold Plates are automatically fed into the cell. A gantry robot equipped with a multi-cup vacuum gripper transfers several parts simultaneously, while each component is identified through its unique 2D Data Matrix code, ensuring complete traceability from the very beginning of the inspection process.
OPERATIONS
Helium Gas Leak Test
Each Cold Plate is tested inside a vacuum chamber using high-sensitivity helium leak detection. The system accurately measures the leak rate, ensuring every cooling circuit meets the required tightness specifications before the component proceeds to the next stage.
OPERATIONS
Dimensional & Vision inspection
A flatness inspection verifies one of the most critical characteristics of the Cold Plate, ensuring proper thermal contact during operation. The integrated vision system complements the process by inspecting key geometric features and the overall surface condition of each part.
OPERATIONS
Laser marking 2D reading
Each Cold Plate is permanently marked with a unique 2D Data Matrix (2DM) code using a laser marking system. The code is immediately verified to ensure readability, linking all inspection and test results to each individual part and providing complete product traceability.
