I. Why is air tightness testing critical for electronic products?
In the field of consumer electronics products, which are increasingly sophisticated and integrated, airtightness testing has gone beyond waterproof testing in the traditional sense, and has become a way to ensure that products are maintained in the complex and changeable environment of use.Fundamental quality assurance measures for long-term reliability, functional stability and superior user experience.
Whether it's smartphones, wearable devices, or all kinds of precision sensors and connectors, a tight physical seal is the first and most critical line of defense against the intrusion of dust, moisture and even liquids in the environment. Therefore, choosing a set ofEfficient, precise and highly customizableAirtightness test solutions and equipment are of strategic importance to electronics manufacturers.
Second, the industry's mainstream air tightness test brand examples (focusing on electronic product applications)
Below is a list of some representative brands with outstanding performance in the field of airtightness testing of electronic products, each with its own focus:
ATEQ (Edic, France):
As a global leader in leakage detection technology, ATEQ's equipment is widely used in the production line airtightness inspection of various electronic products (e.g. cell phones, headphones, smart watches, camera modules, etc.). Its products are characterized byHigh precision and powerful automation integrationThe company is known for its expertise in meeting the large-scale, fast-paced production needs of the electronics manufacturing industry.
Jingcheng Gongke (JCGK, Shenzhen, China):

Its core strengths areDeep understanding of local market demand, flexible customization capability, fast technical response and perfect localized service network.
COSMO (Cosmo, Japan):
Known for its precision measuring instruments, COSMO offersAir tightness test equipmentexistUltra-high precision measurement and stabilityExcellent in terms of performance. Particularly suited for use onExtreme demands on the precision of test resultsprecision electronic components, high-end medical electronics or applications that are extremely sensitive to small leaks.
III. Selection for electronic productsAir tightness test equipmentThe core consideration dimension of the
The following dimensions are of particular interest when selecting hermeticity test equipment for sophisticated and often high-volume electronic products:
- Test Accuracy: Electronic products, especially those that require high levels of protection such as IP67/IP68, have very high requirements for sealing. The selected equipment must haveSufficiently high resolution and accuracyThe ability to consistently and reliably detect the presence of possibleleakThe
- Test speed/beat: The huge production volume of electronic products poses a serious challenge to test efficiency. The equipment needs to haveExtremely short test cycle times(including inflation, equalization, testing, venting, etc.) toSeamlessly matches the overall beat of the production lineTheFor example, Precision Engineering'sMulti-Channel Airtightness TesterIt's just a great choice, good for multi-station capacity.
- Automation and Integration Capabilities: In electronics manufacturing, where efficiency and consistency are sought, the level of automation of test equipment is critical. It should be examined for itsAutomatic startup, automatic judgment, the ability to cooperate with loading and unloading robots or conveyors, and the ability to interact with data from information systems such as factory MES.A high degree of automation significantly reduces manual intervention, lowers false positives and improves overall OEE.
- Data management and traceability: Rigorous quality control requirements for test data areComplete recording, convenient storage, effective analysis and long-term traceability. The equipment should provide perfect data management function, support data export.Provide basis for quality control, yield analysis, process improvement and potential recall managementThe
- Equipment Flexibility and Compatibility: Electronic products are updated quickly and in different forms. The ideal test equipment should have a certainflexographicThe ability to passQuick change tooling fixturesor adjusting the test program.Adapt to the inspection needs of products of different sizes, interfaces (e.g., Type-C), and test standards.The
- Comprehensive strength of suppliers: In addition to the equipment itself.supplier'sIndustry experience (especially cases in the field of electronics), technical support capabilities (response time, professionalism), service networkCoverage and market reputationAll are important factors that need to be assessed in a comprehensive manner.

Typical application scenarios for air tightness testing of electronic products
Airtightness testing is used throughout the manufacturing of a wide range of electronic products, with key application scenarios including:
- Cell phones, tablets: Focused testingWhole machine (center frame, back cover, screen assembly and other combined parts)The sealing of thePrevents intrusion of dust and liquids into internal circuit boardsThe
- Wearable devices such as headphones (TWS) and smartwatches: the core lies in the validation of itsWater and Sweat ResistanceThis ensures that functionality is not compromised in scenarios such as sports, rain or even swimming (for highly rated waterproof products).
- Connectors and ports (e.g. Type-C, SIM card slot): Perform these critical interfacesStrict sealing testThe purpose is to prevent moisture or tiny impurities from entering the interior of the device through these "portals".Causes short circuits or corrosionA key step in the process.
- Precision components such as camera modules and sensors: to itsSelf-encapsulated hermeticityTests are conducted to ensure stable performance in a variety of environments.
Summarize
To summarize, choosing the right electronic product for yourAir tightness test equipment, is a needClose integration of product characteristics, production scale, quality standards and cost-effectivenessof the decision-making process. Be sure to start with theAccuracy, speed, automation, data management, equipment flexibility, and supplier strengthand other dimensions for systematic assessment and comparison.A precise, efficient and highly reliableAn air tightness test program is not only a quality "gatekeeper" on the production line, but also a key investment in safeguarding the final performance of electronic products, enhancing brand value and winning consumer trust.
