Abstract: A chip-transferring module, and a device and a method for transferring and bonding chips are provided. The chip-transferring module includes a mounting main body, a light-transmitting member, a first gas guiding structure and a second gas guiding structure. The mounting main body has a first accommodating space and a second accommodating space. The light-transmitting member is disposed in the first accommodating space. The first gas guiding structure is disposed in the mounting main body and has a plurality of suction openings exposed out of the mounting main body. The second gas guiding structure is disposed in the mounting main body and has at least one intake opening communicating with the second accommodating space.

Abstract: A method for soldering electronic components includes providing a circuit substrate; providing a plurality of electronic components; placing the plurality of electronic components onto the circuit substrate; applying a conductor between the plurality of electronic components and the circuit substrate; providing an energy source which projects an energy beam with a first coverage; enlarging the energy beam and projecting the energy beam onto the circuit substrate with a second coverage; and melting the conductor within the second coverage via the energy beam and fixing the corresponding electronic components on the circuit substrate through the melted conductor. Besides, a method for manufacturing a LED display is disclosed.
