The Filmetrics F42 is a thin-film thickness measurement system that uses spectral reflectance to measure film thickness. The F42 can map over one million points with a spot size as small as 3 microns. The F42 operates over a wavelength range of 400-800 nm and measures thickness from 35 nm to 3 µm.[1][2]

What it is

The Filmetrics F42 is a thin-film thickness measurement system.[1][2]

The Filmetrics F42 is an optical film profilometer and thickness measurement instrument for surface films.[2]

How it works

The Filmetrics F42 uses an integrated CCD camera and live video to locate measurement sites.[1][2]

The Filmetrics F42 makes a thickness measurement at each displayed pixel and can generate a gradient map from more than one million individual thickness values.[1][2]

Where it fits in the process flow

The Filmetrics F42 supports non-destructive in-situ thickness measurement on individual features of production printed circuit boards and related surface-finish structures.[3]

Applications

The Filmetrics F42 is used for printed circuit boards, semiconductor fabrication, and liquid crystal and OLED displays.[1][2]

The Filmetrics F42 supports OSP coating measurement on printed circuit boards.[3][2]
