Intelligent sensors with integrated digital signal processing have become prevalent in an increasing number of applications. As the considerable gain in interference immunity, repeatability, durability and reliability of the gages does not involve any price increase, it is merely a matter of time before digital also will dominate in the field of coating thickness measurement.
Critical dimensions in semiconductor manufacturing are in the deep sub-micron and nanometer range. Over time, specialized measurement systems suitable for these dimensions have been developed with the necessary accuracy and resolution for process control.
Reviewing basic tips on the use of precision instruments can help operators use the tools to their full potential and ultimately save time, reduce errors and increase productivity.
Anyone who understands the third-party certification process knows that one of the most important questions to ask is, “How do I know a certification body is qualified to audit my organization?”
Increasing globalization and economic conditions have driven organizations to place a greater focus on productivity and quality. Today some manufacturing are benefiting from technology innovation, such as automated testing systems, which increase productivity by having the ability to produce goods faster while maintaining high levels of quality.
As of 2008, tens of thousands of video measuring machines are in broad use by manufacturers around the world. It has been just more than 30 years since the first video measuring systems were developed in the United States for dimensional measurement applications in manufacturing quality control.
An innovation in surface analysis software means that it is now possible to work with 4-D (X, Y, Z, T) data and analyze the way that a 3-D surface changes with respect to time or another physical dimension.
The optical encoder has two main parts: the optical graduation and the electronic eye, called the scanning unit or reader head. Optical encoders, in a sense, are transducers, converting a measured length or movement into a series of manageable electrical counts, each count representing a precise distance.
There are two generally accepted reasons why manufacturers measure roundness of components. The first is to sort nonconforming parts based on a customer-supplied blueprint before shipment to the customer; the second is to control the process tool with immediate feedback.
Advanced Product Quality Planning (APQP) and Production Part Approval Process (PPAP) activities can be likened to the Herculean task of cleaning the Aegean stables translated into the world of quality systems.
