An Area-Based Prior Value Method for Detectionof Micro Contamination in Hard Disk Drives
Sandnes, Frode Eika; Muneesawang, Paisarn; Ieamsaard, Jirarat (Journal article; Peer reviewed, 2017)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 ... -
Automatic Optical Inspection of Solder Ball Burn Defects on Head Gimbal Assembly
Ieamsaard, Jirarat; Muneesawang, Paisarn; Sandnes, Frode Eika (Journal of Failure Analysis and Prevention;Volume 18, Issue 2, Journal article; Peer reviewed, 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 ... -
Detection of micro contamination in hard disk drives using angle measurements and Bayesian classification
Ieamsaard, Jirarat; Sandnes, Frode Eika; Muneesawang, Paisarn (Journal of Computers;Vol. 29 No. 1, 2018, Journal article, 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 ... -
Detection of micro contamination in hard disk drives using maximum likelihood estimation and angle detection
Ieamsaard, Jirarat; Muneesawang, Paisarn; Sandnes, Frode Eika (Chapter; Peer reviewed; Chapter, 2016)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 an image-based automatic ... -
Image based contamination detection on hard disk head gimbal assembly
Ieamsaard, Jirarat; Muneesawang, Paisarn; Sandnes, Frode Eika (SITIS 2015 - The 11th International Conference on Signal Image Technology & Internet System;, Peer reviewed; Chapter, 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 ... -
Reducing False Detection during Inspection of HDD using Super Resolution Image Processing and Deep Learning
Ieamsaard, Jirarat; Sandnes, Frode Eika; Muneesawang, Paisarn (Journal article; Peer reviewed, 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 ...
