Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a resin sheet without a bonding layer is used for thermocompression bonding, then residue issues are prevented, but fixation strength to the annular frame deteriorates
Solution Approach 1:
The bonding sheet is designed with non-uniform thickness, featuring a thicker first region and a thinner second region. This local quality variation allows the thicker first region to provide sufficient fixation strength to the annular frame, while the thinner second region prevents residue formation on the workpiece surface, thus resolving the contradiction between fixation strength and residue prevention.
2Stability of the object's composition
If an adhesive tape with a bonding layer is used, then irregularities are absorbed, but device operation fails due to residues
Solution Approach 1:
The bonding sheet incorporates a thicker first region that can absorb irregularities on the workpiece surface, while the thinner second region ensures no residue remains after processing. This local quality differentiation resolves the contradiction between irregularity absorption and residue prevention.
3Object-generated harmful factors
If the bonding sheet is made uniformly thin, then residue is prevented, but fixation to the annular frame becomes insufficient
Solution Approach 1:
The bonding sheet features a non-uniform thickness distribution with a thicker first region for reliable fixation to the annular frame and a thinner second region for residue-free processing. This local quality variation resolves the contradiction between fixation reliability and residue prevention.

AI summary
A processing method of a workpiece includes an integration step of heating and compression bonding a thermocompression bonding sheet to an annular frame that has an opening to receive the workpiece therein and to the workpiece received in the opening, whereby the annular frame and the workpiece are integrated via the thermocompression bonding sheet, and a processing step of processing the workpiece integrated with the annular frame via the thermocompression bonding sheet. In the integration step, the thermocompression bonding sheet is pressed against the annular frame that has been heated by a heat table with a heat source included therein, by a heat roller with a heat source included therein while being heated by the heat roller, whereby the thermocompression bonding sheet is fixed to the annular frame.
