Device for drawing flexible circuit board and control method thereof

Abstract

The invention discloses a device for drawing a flexible circuit board. The device comprises a machine frame, an extrusion unit, moving parts and a control circuit, wherein the moving parts are on X, Y and Z directions; the machine frame includes a chassis, and left and right lateral plate brackets; the moving parts on the X, Y and Z directions are installed and are fixed on the machine frame; each of the three moving parts consists of a polished rod, a screw rod and a stepping motor; the extrusion unit is arranged on the Z direction; a slowdown stepping motor on the extrusion unit drives a gear, and the gear drives a bolt, thereby achieving a pushing-extruding effect; and a conductive silver paste is adopted by an extrusion material and is used for drawing the flexible circuit board on a flexible material such as paper, cloth material and the like. According to the device for drawing the flexible circuit board and the control method thereof disclosed by the invention, a printing manner is adopted to manufacture a circuit board, so the manufacturing manner of the traditional circuit board is broken through, and the device for drawing the flexible circuit board and the control method thereof are innovations of a circuit board manufacturing process; and the circuit board manufacturing process is simple, and the consumption time is short.

Description

technical field [0001] The invention belongs to the technical field of circuit board production, and in particular relates to a device design for drawing a flexible circuit board. Background technique [0002] Flexible Printed Circuit (FPC or "soft board") is a highly reliable and excellent flexible printed circuit board made of polyimide or polyester film as the base material. It has many advantages that rigid printed circuit boards do not have, such as high wiring density, light weight, thin thickness, and good bendability. The use of FPC can greatly reduce the volume of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Looking at the existing technologies, there is no combination of printing technology and circuit boards. Therefore, the research on the device for drawing flexible circuit boards that combines the rapid prototyping technology of printing with the produc...
