This white paper explores how Prescale contact pressure-indicating film can reveal hidden contact pressure variations that conventional force and torque measurements may miss. Through electronic manufacturing applications such as wafer bonding, thermal interfaces, flip-chip assembly, lamination, and semiconductor packaging, it demonstrates how visual pressure mapping can identify issues including warpage, fixture drift, bonding-head misalignment, and uneven loading. By making pressure distribution visible, Prescale helps engineers improve process validation, troubleshoot non-uniformity, enhance repeatability, and ultimately improve product quality and manufacturing yield.
