Ensuring Reliability: A New Method for Measuring Pressure Distribution During Encapsulation

November 23, 2010 5:45 am | by Dr. Thomas Schreir-Alt, Fraunhofer IZM, www.izm.fraunhofer.de, and Jeffrey G. Stark, Sensor Products Inc.,www.sensorprod.com | Comments

The integration of sensors and actuators into encapsulated multi-chip modules creates formidable challenges to characterizing and controlling process pressure. However, a new measurement method developed by Fraunhofer IZM shows that pressure-indicating sensor film can fully characterize the area pressure distribution on the cavity and on substrate surfaces within a mold cavity during encapsulation.
