摘要:
A machine and method for subdividing into individual substrates a wafer which is prescored with a pattern of intersecting score lines defining the substrates. The wafer is progressively directed over a first wafer-engaging surface substantially paralleling one set of score lines, and this surface cooperates during a breaking operation to impart a localized force at a score line in the set. The wafer is halted during the breaking operation, after which the broken-off portion is directed over a second wafer-engaging surface substantially paralleling the other set of score lines. This second surface cooperates, during a substrate breaking operation, to apply a localized force adjacent a score line of the other set. The broken-off portion is halted during this latter breaking operation at which a substrate is separated from the broken-off portion of the wafer.

摘要:
Porous films are provided which include a blend of a film forming polymer and a non-film forming material, the film having a network of pores or channels throughout the film. The porous polymer films are formed between 0° and 80° C., retain porosity at elevated temperatures and are non-friable. A process for preparing porous polymer films and their applications are disclosed.
