  • Composite sheet for mounting a workpiece and the method for making the same
    Patent number: 8087975
    Abstract: The present invention relates to a composite sheet for mounting a workpiece and a method for making the same. The composite sheet includes a buffer layer and an adsorption layer. The buffer layer has a plurality of continuous pores. The adsorption layer is located on the buffer layer for adsorbing a workpiece, and the compression ratio of the buffer layer is higher than that of the adsorption layer. Thereby, due to low hardness, good adsorption effect, and high compression ratio, the composite sheet of the present invention has good buffer effect.
