    the Importance of WVTR Testing for Semiconductor Package 2023-12-18
    A semiconductor package is a metal, plastic, glass, or ceramic casing containing one or more discrete semiconductor devices or integrated circuits. Individual components are fabricated on semiconductor wafers (commonly silicon) before being diced into die, tested, and packaged. Water Vapor Transmission Rate (WVTR) testing is critical for semiconductor packaging for several reasons: 1. Protection Against Moisture: Semiconductors are highly susceptible to damage from moisture. Moisture can lead to corrosion of the metal interconnects, oxidation of the lead frames, and other moisture-related failures. WVTR testing ensures that the packaging material has a low permeability to water vapor, thereby protecting the semiconductor from moisture. 2. Reliability and Performance: The reliability of semiconductor devices is paramount, especially in critical applications such as automotive, aerospace, medical, and military. WVTR testing of the packaging material ensures that devices will perform reliably over their intended lifespan. 3. Preventing Delamination and Internal Stresses: Moisture inside the package can cause the different materials within the semiconductor package to expand at different rates, leading to delamination and internal stresses. These can cause cracks and other failures. WVTR testing helps in selecting materials that minimize these risks. 4. Avoiding "Popcorning" During Solder Reflow: The solder reflow process involves high temperatures that can cause trapped moisture to expand rapidly, potentially causing the package to crack or "popcorn." This can lead to catastrophic failure of the semiconductor device. WVTR testing helps to ensure that packaging materials are sufficiently moisture-resistant to prevent this. 5. Quality Control and Assurance: WVTR testing is part of comprehensive quality control and assurance programs for semiconductor manufacturing. It helps to verify that packaging materials meet the required specifications for moisture barrier properties. 6. Compliance with Industry Standards: Various industry standards, such as those set by JEDEC, may specify WVTR requirements. WVTR testing ensures compliance with these standards, which is important for interoperability and reliability across different environments and applications. 7. Long-Term Stability and Shelf Life: Semiconductor devices may be stored for extended periods before being used. WVTR testing ensures that the packaging can protect the device from moisture for the duration of its shelf life. 8. Cost Savings: By ensuring that the semiconductor packaging has a low WVTR, manufacturers can avoid costly failures and warranty claims. It is much more cost-effective to test and ensure proper packaging than to deal with the fallout of device failures in the field. In summary, WVTR testing is a key aspect of ensuring the durability and reliability of semiconductor packages, which in turn affects the performance and longevity of electronic devices.

    The integrity of the packaging material during the transport of the product is very important for the manufacturer. 1. Protecting products from damage: During transportation, products may be affected by various adverse factors such as extrusion, collision, vibration and humidity. If the packaging material is not strong enough or does not have good cushioning properties, the product may be damaged during transport, leading to quality problems and customer dissatisfaction. The right packaging material can provide protection and ensure that the product remains intact during transportation. 2. Enhance product image and brand value: The packaging of the product is the part that comes into contact with the customer for the first time. Good packaging can leave a good impression on the customer and enhance the image and brand value of the product. If the packaging material is damaged, dirty or unattractive, it may leave an impression of poor quality to the customer and even have a negative impact on the brand image. Keeping packaging materials in good condition is therefore essential to enhance the image of the product and the value of the brand. 3.

  • Solar backsheet water vapor barrier performance test method
    Solar backsheet water vapor barrier performance test method 2023-01-13
    Abstract: Water vapor transmission rate is an important performance index to characterize the solar backsheet's barrier performance to external water vapor (moisture), which directly affects the working condition and service life of solar cells. This paper uses the W413 2.0 infrared water vapor transmission rate tester developed by Guangzhou Biaoji Packaging Equipment Co., Ltd. to test the water vapor transmission rate of solar backsheet samples, and introduces the test standard, test process and test results for reference of major enterprises in selecting water vapor barrier testing equipment and test methods. In the field of solar photovoltaic power generation, solar backsheets play an important role. Usually, the solar backsheet is located at the outermost layer of the solar cell module's backside, thus playing a protective and supporting role for the solar cell module. The backsheet should have reliable electrical insulation, water vapor barrier, aging resistance, mechanical strength and toughness to keep the solar cell in the best working condition and maintain a service life of 25 years. Water vapor barrier performance is one of the important indicators to measure the performance of solar backsheet. If the solar backsheet has poor water vapor barrier performance, water vapor penetrating into the encapsulation system through the backsheet will affect the EVA bonding of the encapsulation film, causing the backsheet and the encapsulation film EVA to delaminate, causing the cell to be oxidized and thus seriously reducing the cell power generation efficiency and the service life of the module. As the solar cell set is placed outdoors for a long time, the humidity is greater on rainy days and water vapor has a greater impact on the solar PV module. Therefore, it is very important to conduct water vapor transmission rate test on solar backsheet to evaluate its water vapor barrier performance. 01 Testing standards The equipment used in this test is the W413 2.0 infrared method water vapor transmission rate tester developed by GBPI.
