Background
The lamp area of prior art preparation, what adopted is that the leg all distributes and forms at the LED lamp pearl preparation of two sides, for example, 6 foot lamp pearls that RGB lamp pearl was used, 6 feet are respectively on two limits of lamp pearl, the three foot in a limit, the problem of existence as follows:
the lamp beads are welded on the circuit board when the three pins on one side are used, particularly when the lamp beads are welded on a flexible circuit board, one of the pins is easy to be subjected to insufficient soldering, the density of the pins is high, the short circuit of tin is easy to be connected, and the density of the pins after the insufficient soldering is high, and the short circuit of tin is easy to be connected when the maintenance is carried out.
Secondly, three pins which need to be conducted on each side of the lamp bead are required to ensure that insufficient solder joint is generated during welding and the lamp bead is convenient to maintain and needs to be bent into a three-dimensional multi-surface solder pin, so that when the lamp bead is used as a planar single-surface solder pin, the yield is low during welding, particularly the insufficient solder joint of the middle solder pin is serious, many enterprises in the industry have six flat solder pins on two sides, and three flat solder pins on two sides all fail due to the above problems, so that six pins currently made in the industry are three-dimensional multi-surface solder pins on two sides and three pins on one side, and why the lamp bead is required to be made as a flat solder pin? The main reason is that when the flat welding foot is made, because no metal is bent and more metal is needed, the utilization rate of the material for manufacturing the lamp bead support is improved by more than 25%, the flat welding foot support is also thinner than the bent support by more than 40%, the total cost can be saved by 30%, and the support is thin, and when the lamp bead is packaged by the support, the packaging glue can be saved by 50%.
And thirdly, 6 pins are distributed on two edges, when the size of the RGB lamp bead is smaller, the density of the welding pins is higher, the short circuit of tin connection is easier, the small-size lamp bead is more difficult to use, and the cost of manufacturing the large-size lamp bead for the lamp strip cannot be reduced.
And fourthly, the size of the RGB lamp bead cannot be reduced, and the matched flexible circuit board cannot be reduced, so that the cost for manufacturing the lamp strip cannot be reduced.
In order to solve the problem which is not solved in the industry all the time, the LED lamp bead can be made small, the circuit board can be made narrow, the cost of the lamp strip is reduced, and a good using effect can be achieved, the lamp strip manufactured by the RGB lamp beads with welding legs on multiple sides is manufactured by the following method, and the technology is overcome:
the method comprises manufacturing lamp beads with a support having multiple sides provided with solder feet, designing and manufacturing the solder feet of the lamp bead support having multiple solder feet on three or more sides of the bottom of the support, exposing metal on the side of the support, designing and manufacturing metal contacts on one or more sides of the support, exposing the metal contacts from the side of the support, forming conductive connection between the metal of the metal contacts and the solder feet in the support, forming multiple metal electrodes on the bottom of the support cup, respectively forming connection with multiple solder feet outside the support, respectively fixing three chips containing red light, green light and blue light on the metal electrodes in the support cup, respectively forming conduction between each chip and the electrode on the support after wire bonding by a wire bonding machine, applying packaging glue on the support, sealing the chips and the electrodes, heating makes glue solidification, then lights on the beam splitter and detect the separation, during the detection, two sides that the detector pressed from both sides and surveyed the lamp pearl, press from both sides a plurality of electrodes that survey the machine and touch the leg that these two sides expose simultaneously and the metal contact that these two sides expose, make LED light and detect the separation, make the RGB lamp pearl that a plurality of limits all had the leg after the separation, then use RGB lamp pearl welding makes the lamp area on the flexible line way board, for above the support preparation low-cost little lamp pearl, low-cost little lamp pearl lamp area, moreover when the preparation lamp pearl, though the leg distribution of lamp pearl is in three or the more than three side, still can use low-cost clamp to survey the machine and press from both sides and survey both sides and accomplish the test to the lamp pearl.
