An Area-Based Prior Value Method for Detectionof Micro Contamination in Hard Disk Drives
This paper presents a new area-based prior value technique for the improvement of automatic visual inspection in hard disk drive manufacturing. Micro-contaminations are detected on the air-bearing surface of the head gimbal ...
Reducing False Detection during Inspection of HDD using Super Resolution Image Processing and Deep Learning
(Universiti Teknikal Malaysia Melaka, 2017)
High false detection rates are a key reliability challenge in the Hard Disk Drive (HDD) industry. Therefore, automatic visual inspection is increasingly employed for HDD inspection. In order ...
Detection of micro contamination in hard disk drives using maximum likelihood estimation and angle detection
Micro contamination is one of the critical defects that occur on the head gimbal assembly (HGA). The HGA is a key component of the read/write assembly of a hard disk drive. This paper presents ...
Automatic Optical Inspection of Solder Ball Burn Defects on Head Gimbal Assembly
(Springer Verlag, 2018-02-23)
The detection of low quality solder joint quality in hard disk drive (HDD) manufacturing is a time consuming, error-prone and costly process that is often performed manually. This paper thus proposes two automated optical ...
Image based contamination detection on hard disk head gimbal assembly
(IEEE Computer Society, 2015)
Contamination may appear in various stages of hard disk manufacturing including the head gimbal assembly. Currently, the detection of contamination requires manual intervention. An image based automatic contamination ...
Detection of micro contamination in hard disk drives using angle measurements and Bayesian classification
(Computer Society of the Republic of China, 2018)
Micro Contamination has been a major critical defects peculiar to the hard disk drive assembly particularly to head gimbal assembly compartment and it occurs mainly on the airbearing surface. Consequently, reliable measures ...
