The new generation of surface measurement and analysis techniques

Development/Diagnostics /Production Monitoring. Whether your costomer 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.

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 degrees to the grating and a camera perpendicular to the grating. Its optical configuration integrated with the heating chamber is shown in the figure below. A technique, known as phase stepping, is applied to shadow moiré to increase measurement resolution and provide automatic ordering of the interference fringes. This technique is implemented by vertically translating the sample relative to the grating.
