Optical 3D metrology enables fast, non-contact surface roughness measurement of defects and roughness for precise ...

Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...

Two questions asked in this paper were: is the measurement by 4D InSpec equivalent on the original surface in respect to a replica, that is, how similar are the results? And: under what circumstances ...

Premature finishing, overworking the surface and inadequate curing are typical causes of surface defects on exterior slabs. Some of these defects include premature wear, scaling, mortar flaking and ...

Borescopic visual inspection may be appropriate for small parts with areas not visible to the naked eye. Even with all the high-tech testing and inspection techniques in use today, basic visual ...

Detecting macro-defects early in the wafer processing flow is vital for yield and process improvement, and it is driving innovations in both inspection techniques and wafer test map analysis. At the ...

Several equipment makers are ramping up new inspection equipment to address the growing defect challenges in IC packaging. At one time, finding defects in packaging was relatively straightforward. But ...
