A bonding apparatus includes a first holder, a first transforming device, a second holder, a second transforming device, a suction device and a control device. The first holder attracts and holds a first substrate from above. The first transforming device transforms the first substrate held by the first holder such that a central portion of the first substrate is protruded downwards. The second holder is provided under the first holder, and attracts and holds a second substrate, which is to be bonded to the first substrate, from below. The second transforming device transforms the second substrate held by the second holder such that a central portion of the second substrate is protruded upwards. The suction device generates different attracting forces in multiple division regions included in an attraction region of the second substrate. The control device controls the suction device.

Sealing body
11667421 · 2023-06-06 · ·

The invention relates to a sealing body, where heat-producing elements of a heating element are contacted from the rear side thereof. Other aspects relate to a sealing body where the site of the heat production and the site of the heat dissipation (i.e. the point of action) are as close to each other as possible. Other aspects relate to a sealing body comprising a heat element with a built-in temperature sensor. Other aspects relate to a sealing body with a defined sealing contour. Other aspects relate to a sealing body having a three-dimensionally structured contact surface. Other aspects relate to a sealing body with a circular, annular, or strip-type heat element. Other aspects relate to a sealing body with built-in electronic circuits. Other aspects relate to a sealing body that can cool the heating element as required. Other aspects relate to a sealing body that can suck up the material to be welded.
