Abstract

The invention relates to the field of circuit board production technology, and discloses a spherical circuit transfer printing technology. The technology comprises the following steps: 1, installing a spherical substrate; 2, enabling the spherical substrate to be magnetized, and spraying iron powder to the surface of the substrate through a power spraying mechanism; 3, rotating the substrate to a zero position, and moving a printing mechanism to a part exactly above the substrate; 4, enabling the printing mechanism to draw the surface of the substrate through melt fine copper during the rotating of the substrate, and forming a spherical circuit; 5, rotating the substrate to the zero position, and limiting the rotation of the substrate; 6, moving the printing mechanism, moving the die with a hemispherical groove to a part exactly above the substrate, moving the die downwards, enabling a part, provided with the circuit, of the substrate to be placed in the groove, and sealing the mouth of the groove; 7, injecting a liquid substrate material into the groove of the die, and taking out a circuit board after the substrate material of the circuit board is solidified. The invention aims at providing the spherical circuit transfer printing technology, so as to product the spherical circuit board.

Description

technical field [0001] The invention relates to the field of circuit board production technology, in particular to a technology for producing spherical circuit boards. Background technique [0002] The circuit board is an insulating board with connected conductors, on which electronic components are fixed and connected to form a circuit. The current production of circuit boards generally adopts copper foil coating on the substrate, the substrate and copper foil are bonded through the glue layer, and then photolithography, corrosion, post-processing processes, etc. are performed. Most of the produced circuit boards are planar circuit boards, and even the flexible printed circuit board (FPCB) is also a plane that can be bent into an arc. [0003] For some special devices, such as making spherical LED lighting devices and spherical displays, it is necessary to print spherical circuits on the spherical base surface. The existing circuit board production process, especially the...
