Light-transmittal pressing plate, pressurizing assembly, heating and pressurizing device and light-emitting chip transfer apparatus

Abstract

A light-transmitting pressing plate comprises a first surface and a second surface in parallel to each other, and the light-transmitting pressing plate allows a laser of a target wavelength to be transmitted in a first direction from the first surface to the second surface. Under the action of pressure and the laser of the target wavelength, the light-transmitting pressing plate is used for transferring light-emitting chips on a first substrate to a second substrate, the first substrate being located on one side close to the second surface of the light-transmitting pressing plate and allowing the laser of the target wavelength to be transmitted in the first direction, and the first substrate being closer to the light-transmitting pressing plate than the second substrate. In the present disclosure, the light-transmitting pressing plate provides a basis for pressurizing and laser irradiation, thus achieving the feasibility of mass transfer of light-emitting chips.
