shadow moire warpage measurement
Warpage measurement resolution is 5 microns. Technical. Explanation. Shadow moiré uses geometric interference between a reference grating and its shadow ... , Warpage is dependent on components thickness,. Young's ... Thermal deformation - warpage .... Shadow Moiré – Measurement Results ...,shadow moiré: Referring to an optical noncontact method to measure warpage using a moiré fringe pattern resulting from the geometric interference between a flat reference grating and the projected shadow of the grating on a warped test object. ,The package warpage is measured by “shadow moiré method” or “laser reflection method”. Samples are subjected to heating and cooling while measuring the package warpage at the temperatures specified in 5.2. The measurement points shall not be on the crown ,Over the past decade, the shadow moiré technique has become the method of choice for temperature-dependent warpage measurement. It is estimated that ... ,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 ... ,Out-of-plane displacement (warpage) is a global effect of interfacial stress and displacement. It is also the cause of mis-registration and noncontact between components and their substrates. Moire methods offer noncontact, full-field, high-resolution app
