Measuring Reflective Surfaces


Manufacturers are adopting automated optical inspection (AOI) systems based on phase shift profilometry (PSP) for applications in advanced packaging processes. Many of these processes use front end-like techniques to create connections among die within a package and from the packaged die to the outside world. The technique offers fast, precise measurements of the 10µm to 100µm features that a... » read more

The Need for Speed


We’ve previously identified the convergence occurring between surface mount technologies (SMT), used to connect packaged semiconductor devices on printed circuit boards, and advanced packaging (AP) technologies, in which connections between the semiconductor devices and to the outside world are incorporated in the packaging process using front-end-like, wafer-or panel-based manufacturing proc... » read more

Extending 3D MRS Sensor Technology To Address Challenging Measurement And Inspection Applications


There is an increasing need for highly accurate 3D inspection and measurement capabilities for applications in SMT, semiconductor and metrology markets. 3D Multiple Reflection Suppression (MRS) sensor technology has been effectively combined with Automated Optical Inspection for several years and is now being utilized for many SPI applications such as microelectronics and sub-100-micron sold... » read more
