Automated Optical Inspection and Semiconductors

Computer-based inspection of high-technology hardware has largely replaced manual inspection for a variety of reasons, the main one being the much faster inspection times and the much reliability of the results. This is all the most true regarding semiconductors, which require faultless properties and functioning. RSIP Vision has developed a long expertise in this area, providing many clients with the Automated Optical Inspection systems they wished to have in order to reliably inspect their produced components and devices. Read on to learn about some of these projects.

Defects Detection in Wafers and PCBs

Detection of microscopic defect in wafers and printed circuit boards is a standard procedure in the manufacturing process. The time consuming human inspection has been replaced in nearly all production lines with an automatic in-line camera-based examination, which can be very effective usingcomputer vision and image processing technologies to detect any anomalies. Via algorithms of feature extraction and matching, RSIP Vision is able to track defects leading to dramatically improvements in reliability and usability. Read more...

Flat Panel Display Inspection

This project compares the performance of a new inspection procedure of Flat Panel Displays (FPD) with the results obtained using a previously existing process. The goal was to demonstrate the correct detection and defect position reported by the new technology. This was done by putting in place a system in charge of image acquisition software and control which drives the captured frames to a sophisticated algorithmical registration analysis system developed by RSIP Vision.

Automatic Inspection of Semiconductors

Semiconductors mass production needs exceptional levels of precision. Among the many processes needed to insure quality and reliability of chips, we were asked to verify that silicon chip masks imprint the right information on silicon wafers. This is a complex, multi-process computer vision task, to solve which we produced an advanced algorithmic software and vision system, the key advantage of which resides in the capture of critical errors early on in the semiconductor production process. Read more...

Crack Inspection and Detection

Industrial production is prone to surface defects and it often needs to be inspected prior to shipment, when still in a semi-finished status. Cracks being very frequent in many types of material, vision-based crack inspection and detection is cost effective and offers high reproducibility and reliability. Here is a contact-free procedure using laser scanning, which can be placed in-line for continuous inspection during production. Read more...

Fabric Inspection with Texture Analysis

Vision-based production inspection systems using camera-based scanning are now quite common in in-line production lines such as in steel, leather and fabrics manufacturing. Inspection is a crucial process since it can reduce process and enhance product quality. We recommend here a texture analysis for defect and novelty detection in fabrics and non-structured surfaces. Our fabric inspection algorithms are developed to detect deviations from local pattern and texture, anomalies and defects. Read more...

Automated Defects Detection in Ceramics

When a tile is manufactured in mass production lines, manual inspection becomes a limiting factor to speed of production. This calls for the development of an automated inspection and defects detection in ceramics material, which RSIP Vision has built for one of its clients, generating dramatic improvements in terms of output quality, waste reductions and loss of labor time, all of which benefit the manufacturer's image and profits. Read more...
