Akrometrix AXP3
Shadow Moiré Technology
Shadow Moiré is a non contact, full field optical technique that uses geometric interference between a reference grating and its shadow on a sample to measure relative vertical displacement at each pixel position in the resulting image. It requires a Ronchi-ruled grating, a white line light source at approximately 45℃ to the grating and a camera perpendicular to the grating. Its optical configuration integrated with the heating chamber is shown in the figure to the right.
The new generation of surface measurement and analysis techniques
Development/Diagnostics /Production Monitoring. Whether your customer is the individual consumer or an OEM, the TherMoiré excels at helping you achieve exceptional customer satisfaction.Better than ever, TherMoiré technology can simulate your thermal processing and operating environment conditions, while capturing a complete history of out-of-plane displacement behavior. Applying this critical information to form - or achieve compliance for - component/substrate behavior allowances (i.e. warpage specifications) can directly impact level I & level II assembly yields and enhance product reliability. Below data could be measured: Coplanarity, Sign warpage, Fulfill warpage, Twist, Bow, CTE, etc.

• New Gauges
• New Surface Measurement & Thermal Profiler
• New Surface Analysis Features
• + more minor feature additions and bug fixes
New Gauges :
Max Warpage Gradient (MWG): Quantifies the highest slope area of the data set by looking at height change in a small area around each data point. Primarily useful for comparison of data sets. Only a single highest value is reported.
Average Phase Amplitude (APA): Measurement quality metric showing the average amplitude of the phase curve calculated for each point in the data set. Higher values indicate better overall measurement resolution. This same math is used in phase amplitude thresholding where lower values are masked from the data set.
Average Phase Modulation (APM): Similar measurement quality metric as APA normalized across the dynamic light range of the image. Higher is still better, with values approach 1 in best case.
