A Review and Analysis of Automatic Optical Inspection and Quality Monitoring Methods in Electronics Industry

Abd Al Rahman M. Abu Ebayyeh, Alireza Mousavi
2020 IEEE Access  
Tsai and Hung in [251] proposed a system based on Fourier reconstruction and wavelet transform for inspecting micro-defects such as pinholes, scratches, and particles in TFT-LCD.  ...  During the evaluation of this method, it was observed that it performed well on macro defects like pit and film tear but failed to be effective on micro defects like scratch and spot.  ...  Therefore, it is not straightforward task to choose one keyword to follow in this research.  ...

Development and Characterisation of Novel Biocomposites Fabricated Using Natural Fibres and Rapid Prototyping Technology [article]

Lyes Azzouz, UH Research Archive
Effect of in-situ temperature on the tensile properties have also been studied for a selection of these biocomposites and their failure mechanisms discussed.  ...  Initially, this study focused on establishing innovative methods of flax reinforcement with different polymeric compounds biodegradable and non-biodegradable based such as poly-lactic acid (PLA), polypropylene  ...  Figure 4 - 5 45 SEM images of flax fibre: a) outer surface of the fibre (elementary) with no visible micro-defects along its length, b) cross section of (technical) fibre showing a compacted number of  ...

The Impact of Recycling on the Fibre and the Composite Properties of Carbon Fibre Reinforced Plastics

Jonas Johannes Hüther
This work addresses recycling effects on carbon fibres and their composites.  ...  The bulk moulding compound process appears to be a straightforward recycling route for end-of-life fibres and production waste.  ...  Based on the stress-strain curves and on visual inspections of the failed specimens, two types of failure mechanisms were tendentially detected: The HS specimens tended to fail progressively, with the  ...

Effect of glass compositional variables on the structure and properties of phosphate glass/polyamide 11 hybrids

Luciana Serio
The blending of polymers is a relatively inexpensive method of manipulating their properties and is common practice in the industry.  ...  The experimental results showed that a high amount of SnF2 could act as a proper compatibilizer for the novel Rilsan ® PA 11 matrix.  ...  poor surface finish, the difficulty in orientating glass fibres, the presence of micro-defects at the glass-polymer interface, the high brittleness of the resulting hybrid [8] .  ...
