Convection reflow emulation for Warpage Metrology

The CRE6 is an optional module to the Akrometrix AXP shadow moiré system that allows a user to mirror the thermal environment of a reflow oven while conducting warpage metrology. The newest reflow emulator offered by Akrometrix, the CRE6 features increased heating/cooling rates and improved temperature uniformity.

Neil Hubble, Akrometrix’s Director of Engineering commented, “Akrometrix’s shadow moiré systems have become the industry standard for warpage measurement. With our CRE6, customers will be able to measure warpage on substrates up to 70mm (diameter) with sub-micron z-resolution in a convection reflow environment. Our aggressive heating rates of up to 5^oC/second allow measurements from 25^oC to 275^oC with convective heating and tightly controlled thermal uniformity.”
