This dataset is intended for quality control and risk prevention in semiconductor packaging fields, covering core processes such as chip pin soldering, package shell assembly, and gold wire bonding. Its target users include high-cleanliness nitrile glove manufacturers, semiconductor packaging vendors, and third-party semiconductor material quality assessment institutions. Its core role is to verify whether nitrile gloves meet the stringent requirements of "low particle contamination and low ion corrosion" for semiconductor packaging through standardized cleanliness data from the dual dimensions of particles and ions. It addresses issues including poor chip contact caused by particle shedding on glove surfaces and circuit oxidation induced by residual ions, providing accurate and quantitative basis for glove selection, batch quality sampling inspection, and production process optimization in semiconductor packaging. It can directly reduce the defective product rate in semiconductor packaging (estimated to decrease by 8%-12%), ensure the yield and long-term reliability of chip packaging, and improve the material quality control level in the semiconductor packaging industry. 1. Data Source: The data is derived from a special detection system for semiconductor-grade high-cleanliness nitrile gloves. In accordance with BS ISO23464:2020 (E) semiconductor adaptation standard, two parallel high-cleanliness nitrile glove samples (covering the start, middle, and end stages of production batches) are selected. A liquid particle counter (detection accuracy: 0.1μm) is used to test the number of particles >0.1μm/0.2μm; Inductively Coupled Plasma Mass Spectrometry (ICP-MS, detection limit: ppb level) is used to test metal ions such as Na⁺, Mg²⁺, and K⁺; IC-940 is used to test anions such as F⁻, Cl⁻, NO₃⁻, and SO₄²⁻. Blank group data is collected synchronously. 2. Data Processing: The "dynamic threshold screening method" is adopted. Based on BS ISO23464:2020 (E) and the special requirements of the semiconductor packaging industry, invalid data caused by equipment fluctuations and sampling deviations (such as instantaneous sharp increase in particle count, ion concentration exceeding 3 times the standard deviation) are automatically filtered. The screened data is standardized in a semiconductor scenario-specific format, with unified field names, unit labels, and numerical precision, forming structured data that can be directly connected to semiconductor packaging quality systems. 3. Data Calculation: Actual particle count (cts/cm²) = (Sample particle count - Blank particle count) × Dilution factor (10) ÷ Nitrile glove surface area; Actual ion concentration (μg/cm²) = (Sample ion mean - Blank ion mean) × Dilution factor × Immersion solution volume (0.5L) × Conversion factor (10⁻³) ÷ Nitrile glove surface area. Conversion factor: The coefficient for converting ppt to ug/L is 1/1000. Data Application: Cleanliness grade determination: If the particle count is less than 1000 cts/cm² and the ion concentrations meet the semiconductor packaging limits (Na⁺ < 0.05 μg/cm², Mg²⁺ < 0.004 μg/cm², K⁺ < 0.05 μg/cm², F⁻ < 0.05 μg/cm², Cl⁻ < 2.0 μg/cm², Br⁻ < 0.1 μg/cm², NO₃⁻ < 2.0 μg/cm², PO₄³⁻ < 1.5 μg/cm², SO₄²⁻ < 1.5 μg/cm²), the grade is judged as "Compliant". If any single indicator exceeds the limit, the grade will be downgraded.
