Introduction
1. Background of standard formulation and analysis of technological evolution
Spherical silica powder is a high-performance inorganic material, widely used in electronic packaging, copper clad laminates and other fields. The formulation of GB/T32661-2016 fills the gap in this field in China and standardizes product classification, performance indicators and test methods.
2. Comparison of standard frameworks
| Standard dimensions | GB/T32661-2016 | SJ/T10675-2002 | GB / T1.1—2009 |
|---|---|---|---|
| Scope of application | Electronic packaging material fillers | Silicon dioxide powder for electronic and electrical industry | General rules for the preparation of standardization documents |
| Core indicators | Sphericity, spheroidization rate, median particle size | Powder purity, particle distribution | File structure and specification requirements |
| Update cycle | Once every 5 years | Once every 10 years | Updated irregularly |
3. Implementation suggestions and actual case analysis
In the field of electronic packaging materials, the use of spherical silica powder should pay special attention to the following points:
- Selection: Select the appropriate median particle size (D50) specification according to application requirements.
- Quality control: Strictly test key indicators such as moisture content and sphericity according to the test methods in the standard.
- Storage: Avoid humid environment to ensure stable product performance.
Actual Application Cases
After an electronic packaging company adopted spherical silica powder that complies with the GB/T32661-2016 standard, the thermal conductivity of the packaging material increased by 15%, while reducing the batch failure rate by 10%.
