Abstract

The invention discloses a manufacturing method based on a photocuring 3D printing technology and used for a circuit board. The manufacturing method based on the photocuring 3D printing technology andused for the circuit board comprises the following steps: (1) designing a matrix model and a circuit pattern of the circuit board; (2) setting the printing parameters of the matrix model, and slicingthe matrix model; (3) blending functional photocuring resin; (4) printing a circuit board matrix through a photocuring 3D printing machine; (5) activating the surface of the matrix through laser to form an activated layer attached with a chemical plating catalyst; (6) carrying out chemical plating on the circuit board matrix; and (7) installing electronic components at the corresponding positionsof the circuit board matrix. The manufacturing method is high in machining degree of freedom, and capable of being applied to manufacturing for a three-dimensional circuit and manufacturing for a two-dimensional circuit board. The manufacturing method is capable of conveniently designing the circuit board and the circuit pattern according to the actual user need, and efficiently manufacturing thecircuit board, low in manufacturing cost, short in process flow, and green and environment-friendly.

Description

technical field [0001] The invention relates to a method for manufacturing a circuit board, in particular to a method for manufacturing a circuit board based on photocuring 3D printing technology. Background technique [0002] At present, a large number of electronic components in electronic products mainly rely on printed circuit board technology to manufacture. The circuit board is not only the support of various electronic components, but also the carrier of the electrical connection of electronic components. With the improvement of the integration of electronic components, both industry and consumers want to further reduce the volume of electronic equipment. At this time, electronic components manufactured by relying on printed circuit board technology are too large. In this context, molded interconnect Device technology (MID for short) has been developed, which can make three-dimensional three-dimensional circuits and interconnection devices with electrical functions o...
