PREPARATION METHOD FOR INORGANIC FILLER POWDER WITHOUT MAGNETIC FOREIGN MATTER, AND INORGANIC FILLER POWDER PREPARED THEREBY AND APPLICATION THEREOF
A preparation method for an inorganic filler powder without magnetic foreign matter, comprising the following steps: S1, providing a powder to be processed, and adding water to prepare a first slurry;S2, removing magnetic foreign matter from the first slurry by using a magnetic iron removal device to form a second slurry; S3, drying and granulating the second slurry to prepare dry granulated powder; and S4, removing magnetic foreign matter in the dry granulated powder by using the magnetic iron removal device to prepare an inorganic filler powder without magnetic foreign matter. By the inorganic filler powder prepared by the method and an application thereof, a hidden danger of short life caused by applying an inorganic filler powder having magnetic foreign matter to chip packaging is avoided.
本发明涉及一种无磁性异物的无机填料粉体的制备方法包括以下步骤：S1，提供待处理粉体，加入水，制成第一浆料；S2，将第一浆料用磁性除铁设备除去磁性异物，形成第二浆料；S3，对第二浆料进行干燥、造粒，制成干燥造粒粉；S4，采用磁性除铁设备除干燥造粒粉中的磁性异物，制得无磁性异物的无机填料粉体。本发明还涉及应用该方法制得的无机填料粉体及其应用，避免了带磁性异物的无机填料粉体应用于芯片封装中带来的寿命短的隐患。
