Filling agent of packaging material, preparation method of filling agent, magnetic plastic packaging material and packaging device
The invention provides a filling agent of a packaging material, a preparation method of the filling agent, a magnetic plastic packaging material and a packaging device. The filling agent of the packaging material comprises ferrite particles, the ferrite particles comprise a nickel-copper-zinc ferrite (NiaZnbCucFedO4) material, the value range of a is 0.3 to 0.55, the value range of b is 0.45 to 0.55, the value range of c is 0 to 0.2, and the value range of d is 1.8 to 2; in the ferrite particles, the number of particles with the particle size of 2-11 microns accounts for 50-70%. The filler has the advantages of low relative density, wide absorption frequency band and good high and low temperature performance, so that the overall quality of a packaged device can be reduced, the anti-electromagnetic interference frequency band of the packaged device is improved, and the applicable temperature range of the packaged device is widened.
本申请提供了一种封装材料的填充剂及其制备方法、磁性塑封材料与封装器件。封装材料的填充剂，包括铁氧体颗粒，所述铁氧体颗粒包括镍铜锌铁氧体(NiaZnbCucFedO4)材料，a的取值范围为0.3‑0.55，b的取值范围为0.45‑0.55，c的取值范围为0‑0.2，d的取值范围为1.8‑2；所述铁氧体颗粒中，粒径为2‑11μm的颗粒的数量占比为50‑70％。该填充剂具有相对密度低、吸收频带宽以及高低温性能好的优点，进而可降低封装器件的整体质量，提高封装器件的抗电磁干扰频段以及适用温度范围。
