FPC (flexible printed circuit board) substrate continuous and uninterrupted screen printing ink operation line

Abstract

The invention provides an FPC (flexible printed circuit board) substrate continuous and uninterrupted screen printing ink operation line, and relates to a technology for printing ink on a printed circuit board. The FPC substrate continuous and uninterrupted screen printing ink operation line comprises a first position screen printer, a first position baking oven, a second position screen printer, a second position baking oven and a conveying belt, wherein the first position screen printer, the first position baking oven, the second position screen printer and the second position baking oven are in sequential arrangement in the X direction, the conveying belt is used for conveying an FPC substrate in the X direction, and the FPC substrate sequentially penetrates and walks through the first position screen printer, the first position baking oven, the second position screen printer and the second position baking oven. The defect that the existing screen printing cannot realize the section-by-section uninterrupted printing on the coiled FPC substrate is overcome, infinitely extending ink lines (i.e., conducting lines) can be printed, and FPCs with the unlimited length can be prepared. The defect that the existing screen printing cannot realize the non-stop printing on the coiled FPC substrate is overcome, the continuous and uninterrupted ink printing on the whole coil of FPC substrate can be realized, the quality of the seamless butt joint printing is ensured, in addition, the printing speed is high, the efficiency is high, and the cost is low.

Description

technical field [0001] The invention relates to printing ink technology on a printed circuit board, especially to a continuous and uninterrupted screen printing ink operation line for FPC substrates. The so-called uninterrupted space concept refers to the printing of uninterrupted ink lines on the entire roll of FPC substrate, like wires extending infinitely; the so-called continuous concept of time refers to the continuous operation of the printing process without stopping and waiting. Background technique [0002] FPC circuit boards are called flexible circuit boards, and they are more and more widely used. For example, LED light tubes and LED lighting scenes generally use FPC circuit boards, and many light-emitting diodes (LED lamp beads) and resistor elements are mounted on the FPC circuit boards, and then connected to the power supply. [0003] The FPC circuit board includes a base material (referred to as the FPC base material in this application document), and the FP...
