Embodiment Construction

[0024] Before describing the specific embodiments of the present invention in detail, the term "continuous" in the present invention is defined. In the present invention, the term "continuous" refers to a single double-sided flexible printed circuit board with a length of more than 1 meter. Among them, the more preferred length includes 1-300 meters, for example, 1-200 meters, 1-100 meters, 1-50 meters, 1-25 meters, 5-15 meters, 15-30 meters, 30-50 meters, 50 meters -100 meters, 100-150 meters, 150-200 meters, 200-300 meters, of course lengths over 300 meters are also available, such as 300-500 meters. In addition, the term "double-sided flexible printed wiring board" means that wiring is provided on both sides of the flexible printed wiring board.

[0025] As a preferred embodiment, the circuit on the double-sided flexible printed circuit board of the present invention may be an uninterrupted circuit formed at one time.

Abstract

The invention provides a double-sided flexible printed circuit board comprising two layers of circuit layers and an insulating film layer sandwiched between the two layers of circuit layers. One or a plurality of through holes which are communicated conductively are arranged between the two layers of circuit layers, wherein the double-sided flexible printed circuit board has continuous length. The invention further relates to an LED strip adopting the continuous double-sided flexible printed circuit board. The double-sided flexible printed circuit board overcomes the limitations in length of the prior double-sided flexible printed circuit board, so that shorter flexible printed circuit boards are unnecessarily spliced in making the LED strip adopting the continuous double-sided flexible printed circuit board, the production efficiency and the reliability of products are improved, and the failure probability of the products is greatly lowered. In addition, the labor cost is reduced due to no need of splicing the circuit boards. The invention further provides an LED strip adopting the continuous double-sided flexible printed circuit board.

Description

technical field [0001] The invention relates to the field of flexible printed circuit boards (FPC), in particular to continuous double-sided flexible printed circuit boards produced in rolls. The invention also relates to an LED light strip using the continuous double-sided flexible printed circuit board. Background technique [0002] In recent years, the application of flexible printed circuit boards has become more and more extensive. For example, it can be used to make LED light strips, LED melamine lamps, large antenna circuit boards, neon lights, etc. In the existing double-sided flexible printed circuit boards, due to the limitations of existing double-sided flexible printed circuit board processing equipment, growth process cycle, processing technology, cost and other factors, the continuous extension of a single double-sided flexible printed circuit board finished product The length is usually up to about 1 meter, and is generally a flexible printed circuit strip wi...
