PCB Inspection | Automated Optical Inspection | Qualitas Technologies
A PCB goes through multiple processes while manufacturing and visual inspection checkpoints are crucial throughout the process. There are several stages where vision systems can be deployed to maintain the quality of the circuit boards. During manufacturing of any product, the earlier you detect the defects, the less the cost of reworking would be. A highly accurate machine vision system helps a PCB manufacturer to detect defective boards reaching accuracies of up to 98 percent.

Automated Bearing Inspection- Vision Systems | Qualitas Technologies
Introduction The term “bearing” is derived from the combination of the two words “to bear”, reflecting this component’s ability to bear loads.  A bearing is a common machine element used to regulate relative motion and reduce the friction between moving parts. Metal-on-metal contact results in a large amount of friction, and therefore, by allowing two surfaces to roll over one another, bearings reduce the amount of friction produced and guard the metal’s quality.  The boom

Automated X-Ray Inspection
What is X-Ray Inspection?  X-ray is a kind of electromagnetic radiation with wavelengths shorter than UV rays but longer than gamma rays. The x-rays that carry energy levels above 5 KeV are considered hard x-rays. These hard x-rays are capable of penetrating through a wide range of materials and hence, have widespread applications in the medical and industrial domain.  X-ray inspection is a method that uses x-rays to develop images for viewing and analyzing.

Image Processing Machine Vision
Introduction Machine vision has become the eye of industrial automation. With a machine vision system, repetitive and arduous tasks can be accomplished with tremendous accuracy and high speeds while drastically reducing costs. No wonder it is rapidly gaining traction in many industries. But how does the machine vision system actually accomplish these tasks? Well, a machine vision workflow can be broken down into the following four major processes: Pre-process automation Image acquisition Image processing Post-process

Deep Learning & Neural network | Key Difference Between Deep Learning and Rule-Based Algorithms
What is a Deep Learning neural network? Deep Learning is a subset of artificial intelligence. Just like we have a neural network in our brain, deep learning uses an artificial neural network to use raw input data, model and process multiple kinds of relationships, and transform to outputs parallelly. It involves complex mathematical computations and analysis over hundreds of layers between inputs and outputs using the forward path of data, the backward path of data,

Quantum Efficiency, Sensor Size, and Focal Length- Machine Vision | Imaging Basics – Calculating Lens Focal length
Introduction Every vision system relies on image sensors, processing hardware, and software algorithms to automate repeated and mundane visual inspection applications. Image sensors are solid-state devices that are one of the most significant elements of an MV system. These small digital sensors placed inside industrial cameras work with specialized optics to acquire images so that they can be processed and analyzed further. Their fundamental objective is to convert incoming light energy into electrical signals. But
