Abstract
This disclosure is directed to an apparatus and method for spreading a fluid across a substrate. A spreader for spreading a fluid across a substrate includes a wiper and a frame. The wiper and the frame may mate to permit translation of the wiper across, and with respect to, the frame. The wiper spreads the fluid across the substrate and the frame supports the wiper and the substrate. The frame may also include a ramp to cause a portion of the wiper to lift away from the substrate.
