For example, the Chinese patent with the notification number CN201069069Y discloses a utility model patent named "Soft Waterproof LED Lighting Strip", which realizes the communication between each light strip unit by providing a pair of wire interfaces on the light strip unit. The wires are fixedly connected to each other; another example is that the Chinese patent with the notification number CN201181370Y discloses a utility model patent named "Structure of Light Strips", which can combine two adjacent light strips by heat pressing or soldering iron. Connection of connecting boards; although the above two methods realize the connection of the flexible board, the connection process greatly increases the production cost, and there is also the problem of weak connection and hidden dangers of stability

Description
technical field [0001] The invention relates to a method for manufacturing a flexible circuit board, in particular to a method for manufacturing a flexible circuit board used for an elongated light bar of a liquid crystal backlight module. Background technique [0002] LED (light-emitting diode) is a light-emitting device made of compound semiconductor materials. Compared with traditional backlights, it is used in the field of liquid crystal backlights. Easy to use, simple design of auxiliary optical components and power supply modules, etc., and because the LED light source does not produce any rays, and does not have toxic substances such as mercury, it is a green and environmentally friendly light source. In addition, the planar structure also makes it have Excellent anti-shock performance and thinner and lighter dimensions, the above advantages make LEDs more and more widely used in backlight modules. [0003] Under the prior art, LEDs are welded on a circuit board to f...
