  Strengthening Liquid Cooling Operational Safety: Full-Process Technical Cleanliness Control Empowers Computing and New Energy Industrial Upgrading   As AI computing centers, energy storage power stations, new energy vehicles, and high-end industrial control equipment rapidly evolve toward high power density, miniaturization, and high integration, liquid cooling technology has gradually replaced traditional air cooling as the mainstream thermal management solution. Featuring low energy consumption, precise temperature control, and high heat dissipation efficiency, it perfectly meets the heat dissipation demands of high-density electronic devices. However, with the large-scale popularization of liquid cooling systems, technical cleanliness control challenges have become a critica...

Technical Cleanliness Inspection VDA19.1 & ISO16232: Mitigate Contamination Risks for Electronic Components   Advancements in autonomous driving, in-vehicle communication and electric vehicles have raised stringent performance requirements for automotive electronic systems. Precision components are increasingly sensitive to micro particulate contamination, with particle-induced short-circuit risks growing exponentially. This has become a leading cause of component failure, vehicle recalls and critical safety incidents in intelligent vehicles.     Modern intelligent vehicles integrate dozens of sensors and ECUs. Tiny internal contaminants pose severe safety threats. Conductive particles such as metal debris and welding residues can trigger short circuits, system malfunct...

Technical Cleanliness Testing: Personnel Clothing Requirements for Reliable Test Results   Quick Overview Why is personnel clothing important in technical cleanliness testing? Personnel can become a potential source of contamination through clothing fibers, hair, skin flakes, and dust carried on clothing. These contaminants may affect the sample condition, blank values, and particle test results. In technical cleanliness testing, personnel clothing should be selected according to the test object, environmental conditions, blank value requirements, and contamination risks. Common measures include low-shedding, low-lint cleanroom garments or dedicated workwear, together with clean hoods or caps, powder-free and low-shedding gloves, clean shoes or shoe covers, and masks when necessary.
