Problems solved by technology
[0003] ①. When the three legs on one side are used, the lamp bead is welded on the circuit board, especially when it is soldered on a flexible circuit board, it is easy to cause one of the solder legs to be soldered falsely, and the solder leg density is high and it is easy to short circuit with tin, and the solder leg is soldered falsely The density of rear solder pins is high, and it is easy to short circuit with tin during maintenance
[0005] ③. The 6 pins are distributed on two sides. When the size of RGB lamp beads is made smaller, the density of solder pins is higher, and it is easier to short circuit with tin, which makes it more difficult to use small-sized lamp beads, resulting in the cost of making large-sized lamp beads for light strips. can't come down again
[0006] ④. The size of the RGB lamp bead cannot be made small, and the supporting flexible circuit board cannot be made small, so that the cost of making the light strip cannot be reduced.

Embodiment 1
[0032] 1. Production of punching dies
[0033] Design and manufacture a 2835 LED bracket with 6 feet, a rectangular parallelepiped bracket of 2.8mmx3.5mm, design one soldering leg 1.1 on the two sides with a width of 2.8mm, and design two soldering legs 1.1 on each of the other two sides, a total of 6 soldering legs Feet 1.1.
[0034] 2. The prototype of punching bracket circuit
[0035] The 0.20mm copper strip is prepared, and the 0.20mm copper strip 1.1 is punched into a bracket circuit prototype with a punching die, and then electroplated silver on the bracket circuit prototype, so that the surface of the copper strip is plated with a layer of silver.

The invention relates to a lamp strip made of RGB lamp beads and a manufacturing method of the lamp strip, in particular to the lamp strip which is manufactured by welding the RGB lamp beads on a flexible circuit board, the RGB lamp beads are manufactured by packaging three chips emitting red light, green light and blue light in a support, and the support of the lamp beads is an LED support formed by embedding metal in resin. At least six weld legs are arranged on at least three edges of the bottom of the RGB lamp bead support, the total number b of the weld legs on the support is larger than or equal to 6 and smaller than or equal to 16, the weld legs are exposed out of the side face of the support, the support can be used for manufacturing small RGB lamp beads with low cost, and the lamp strip manufactured by the small RGB lamp beads is low in cost.
Description
technical field [0001] The invention relates to an LED light strip and its application field, in particular to a light strip made of RGB lamp beads and a production method thereof. Background technique [0002] The light strips produced in the prior art are made of LED lamp beads whose soldering feet are distributed on both sides. , with three feet on one side, the existing problems are as follows: [0003] ①. When the three legs on one side are used, the lamp bead is welded on the circuit board, especially when it is soldered on a flexible circuit board, it is easy to cause one of the solder legs to be soldered falsely, and the solder leg density is high and it is easy to short circuit with tin, and the solder leg is soldered falsely The density of the rear solder pins is high, and it is easy to short circuit with tin during maintenance. [0004] ②. There are three feet on each side of the lamp bead that need to be turned on. To ensure that there are fewer false welds dur...
