This apparatus will accurately measure the tack, i.e., stickiness, of various viscous materials, for example, conductive screening paste, vehicles and combinations thereof. In packaging technology electrically conductive lines are formed on substrates from conductive paste materials commonly deposited by screening techniques on ceramic substrates either before or after sintering. The tackiness of the material is a consideration in processing. For example, in using a three-roll mill the vehicle of the paste must maintain a certain tack to adhere to the surface of rotating rollers dragging the agglomerates into the roll nip to achieve particle dispersion.
