A fixture assembly includes a first fixture portion, a second fixture portion that interfaces with the first fixture portion, and a sub-fixture movably mounted to the first fixture portion. A multiple of actuators selectively move the sub-fixture toward the second fixture portion. A method of manufacturing a fan blade includes deploying the sub-fixture from the first fixture portion to effectuate a peripheral diffusion bond to join the blade body and the cover of the fan blade.

Semiconductor device manufacturing method

A pressing area set on a main surface of a plate-shaped holding jig is arranged on contact parts. The contact parts are pressed against a multilayer board while heating the multilayer board and the pressing area of the holding jig is inclined with a warp of the multilayer board. In this way, when pressing for bonding the contact parts is performed, even if the multilayer board is warped by the heating and the contact parts are shifted, the contact parts are pressed against the multilayer board without fail.
