【摘要】：目前的硬盘驱动器，，磁头飞行高度一般在10nm左右，而一颗普通尘粒的直径≥0.3μm，一旦高速运转的磁头碰到这种尘粒，就会造成磁头损伤或者碟面划伤，从而导致硬盘报废。本课题通过对硬盘尘粒的分析研究，以期改善这一点。硬盘生产中防尘研究主要集中在“洁净的环境”和“干净的零部件”这两个方面，论文通过大量的实验研究来分析尘粒的来源，并提出相应的防尘除尘措施，良好的无尘室控制可以满足“洁净的环境”的要求，而采用改善后的超声波清洗参数则可以得到“干净的零部件”。本论文主要工作有：采用检测试验法对F3系列硬盘生产中尘粒的来源进行分析和查找；通过改善防尘室的操作规程和试建模范生产线的方法来改进硬盘生产中的防尘效果，经测试分析硬盘尘粒状况确有改善；在研究了超声波清洗机理之后，采用正交实验法改善超声波清洗参数，以达到获得更干净的零部件；对硬盘生产线防尘除尘进行综合实验，结果表明硬盘尘源性废品率有明显的下降。
[Abstract]:In the present hard disk drive, the flying height of the magnetic head is generally about 10nm, and the diameter of a common dust particle is more than 0.3 渭 m. Once the high speed magnetic head touches the dust particle, it will cause head damage or disk surface scratch, which will lead to the hard disk scrapping. This subject through the hard disk dust particle analysis, in order to improve this point. The dust prevention research in hard disk production mainly focuses on the two aspects of "clean environment" and "clean parts". This paper analyzes the source of dust particles through a large number of experimental studies, and puts forward the corresponding measures for dust prevention and dust removal. Good clean room control can meet the requirements of "clean environment", and "clean parts" can be obtained by using improved ultrasonic cleaning parameters. The main work of this paper is as follows: to analyze and find out the source of dust particles in F3 series hard disk production by means of testing test method, to improve the dust-proof effect in hard disk production by improving the operation rules of dust-proof chamber and the method of building model production line. After testing and analyzing the improvement of hard disk dust particles, after studying the ultrasonic cleaning mechanism, the ultrasonic cleaning parameters were improved by orthogonal test method to obtain cleaner parts and components, and a comprehensive experiment was carried out on the hard disk production line to prevent dust and dust. The results show that the rate of hard disk dust-derived waste is obviously decreased.
