At present, the curing of solder resist ink is often carried out in an oven, and the curing time is about 2 hours each time. Only a single product can be processed each time, and the production efficiency is low; and when the printed flexible circuit board is an ultra-thin product (thickness is about 150μm), it is very easy to produce creases in the process of taking and finishing, thereby reducing the quality of the flexible circuit board; in addition, before the flexible circuit board is placed in the oven for ink curing, it needs to be Glass fiber paper is added between the flexible circuit boards to be cured by the ink, and the glass fiber paper is easy to adhere to foreign matter. Under the high temperature condition of the oven, the foreign matter attached to the glass fiber paper is easy to transfer and absorb on the flexible circuit board, resulting in the failure of the flexible circuit board. poor board quality

The invention relates to a device and method for carrying out printing ink curing on a flexible circuit board. The device for carrying out the printing ink curing on the flexible circuit board comprises a rolling-in device, a drying device and a rolling-out device; and the flexible circuit board enters a conveying unit of the drying device through the rolling-in device, is subjected to printing ink curing in the conveying process of the conveying unit and is then rolled out by the rolling-out device. In addition, the invention also provides a method for carrying out printing ink curing by using the device. The device for carrying out printing ink curing on the flexible circuit board can be used for continuously curing the flexible circuit board roll to roll so that the production efficiency is improved, and also can be used for preventing the flexible circuit board from adsorbing foreign matters and generating crease lines in the printing ink curing process so that the quality of the flexible circuit board is improved.
Description
technical field [0001] The invention relates to a device and a method for curing ink of a flexible circuit board. Background technique [0002] At present, photosensitive solder resist ink is often printed on flexible circuit boards to ensure the solder resistance of flexible circuit boards and the accuracy of solder joint size! The solder resist ink printing process mainly includes the following five steps, namely ink printing, ink pre-drying, ink exposure, ink phenomenon, and ink curing. At present, the curing of solder resist ink is often carried out in an oven, and the curing time is about 2 hours each time. Only a single product can be processed each time, and the production efficiency is low; and when the printed flexible circuit board is an ultra-thin product (thickness is about 150μm), it is very easy to produce creases in the process of taking and finishing, thereby reducing the quality of the flexible circuit board; in addition, before the flexible circuit board i...
