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 the LED lamp bead is made smaller, the density of the solder pins is higher, and it is easier to short-circuit the tin, which makes it more difficult to use small-sized lamp beads

Embodiment 1

[0027] 1. Production of punching dies

[0028] Design and manufacture a 2835LED bracket with 6 feet, a 2.8mmx3.5mm cuboid bracket, design a 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.

[0029] 2. The prototype of punching bracket circuit

[0030] 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.

[0031] 3. Production of PPA resin

[0032] Inject the PPA resin 2.1 on the copper strip with an injection mold on the injection molding machine to form a plurality of bracket cups, and embed the copper prototype circuit in the PPA resin.

[0033] 4. Die-cut the bracket to make 6 welding legs

[0034] Die-cutting is used to make a continuous brack...

Abstract

The invention relates to an LED lamp bead manufactured by a support and a manufacturing method of the LED lamp bead, in particular to the LED lamp bead manufactured by using an LED support packaging chip, the support of the LED lamp bead is an LED support formed by embedding metal in resin, at least three edges of the bottom surface of the LED lamp bead support are provided with a plurality of weld legs, the total number b of the weld legs on the support is more than or equal to 4 and less than or equal to 16, the weld legs are exposed out of the side surface of the support, and the support of the LED lamp bead is provided with a plurality of LED lamp beads. At least three welding feet exposed out of the side faces of the RGB lamp bead are communicated with the LED chip, the LED support is used for packaging and manufacturing the low-cost small-size lamp bead, and tin connection and cold solder joint are not prone to occurring when the LED support is used for welding.

Description

technical field [0001] The invention relates to an LED lamp bead and its application field, in particular to an LED lamp bead made of a bracket and a manufacturing method thereof. Background technique [0002] The lamp beads with multiple legs in the prior art, for example, the 6-pin lamp beads used for RGB lamp beads, the 6 legs are respectively on the two sides of the lamp bead, and there are three legs 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 ...
