  • Patent number: 11211357
    Abstract: A method for processing an ultra-high density interconnect wire under light source guidance, comprising preparing a photo-thermal response conductive paste, and putting it into an air pressure injector; driving the air pressure injector; the air pressure injector extrudes the photo-thermal response conductive paste, so that the photo-thermal response conductive paste is connected with the first chip to form an interconnection wire; stopping extruding the photo-thermal response conductive paste, and driving the air pressure injector to pull off the interconnection wire; a linear light source emits light and irradiates on the interconnection wire to bend to an upper side of a second chip bonding pad; an extrusion mechanism presses a free end of the interconnection wire on the second chip bonding pad; the first chip and the second chip are subjected to glue dripping encapsulation.

  • Publication number: 20210233800
    Abstract: A decoupled XY parallel micro-positioning stage, including a central moving platform, fixed mechanisms, bridge-type micro-displacement amplification mechanisms, a four-bar symmetrical flexible guide mechanism and a piezoelectric ceramic. Each fixed mechanism is arranged between adjacent amplification mechanisms and is symmetrical about X and Y axes centered on the moving platform. The amplification mechanism is symmetrically arranged with respect to the X and Y axes, and includes two first and second longitudinal beams and multiple crossbeams. The two first longitudinal beams are provided in parallel and spaced apart. The two second longitudinal beams are arranged spaced apart between the two first longitudinal beams, and are connected to the two first longitudinal beams via the crossbeams. The crossbeams are connected to the longitudinal beams via a flexible hinge. The piezoelectric ceramic is arranged between the two first longitudinal beams.
