AI Technical Summary
Technical Problem
In the prior art, when manufacturing LED strips, the increased wire width of the conductive circuit board causes the flexible board film to delaminate, and the parallel wire design is prone to short circuits, which cannot meet the current load requirements of longer LED strips.
Method used
By creating notches in flat conductors to increase the spacing with metal foil lines and locally widening the conductors without changing their thickness, combined circuits are formed using die-cutting technology, which avoids short circuits and increases current load.
Benefits of technology
This solution addresses the issue of thin film delamination on conductive circuit boards, improving the yield rate of circuit boards, enhancing current load capacity, and reducing manufacturing costs.

Abstract
The utility model discloses a kind of line clamping circuit board and lamp strip, comprising: first film;Metal foil circuit;Flat conductor circuit, part or all flat conductor circuit is provided with notch, so that part or all flat conductor circuit is not the same in width and narrow;Second film, several pad windows are provided thereon;First film is combined together with second film, and flat conductor circuit and metal foil circuit are clamped between two films;The thickness of flat conductor circuit is greater than the thickness of metal foil circuit;Flat conductor circuit is main circuit, and metal foil circuit is auxiliary circuit, or, metal foil circuit has main circuit, and also has auxiliary circuit;The length of main circuit is greater than the length of auxiliary circuit;The metal exposed in pad window is flat conductor circuit or / and metal foil circuit. Through notch design makes part position narrow, but can make other position keep wider, to increase current load, solve the problem of film separation delamination.
