3528 full-color LED lamp bead support

Abstract

The invention discloses a 3528 full-color LED lamp bead support. The 3528 full-color LED lamp bead support can avoid the dual-welding inclined wiring problem, raises the product performances and meets lamp bead service life and stability requirements. In the 3528 full-color LED lamp bead support, a first isolation strip and a second isolation strip divide an end face of a support bowl cup at one side of a third isolation strip into three parts. A first welding contact is arranged in each part. The longitudinal section of the end part of the support bowl cup is elliptical. Three second welding contacts are arranged in positions, corresponding to the first welding contacts, of an end face of a support bowl cup at the other side of the third isolation strip. The corresponding first welding contacts and second welding contacts are in the same horizontal line. The first welding contacts and the second welding contacts are subjected to welding conduction by gold threads. A bent fourth isolation strip is arranged at the lower end of the third isolation strip in order to make space for the second welding contact in the lowest end. The 3528 full-color LED lamp bead support can be widely used in the LED lamp bead support field.

Description

technical field [0001] The invention relates to a 3528 full-color LED lamp bead bracket, which belongs to the technical field of LED lamp bead brackets. Background technique [0002] At present, the wire bonding process of SMD 3528 lamp beads is based on the bracket to determine the wire bonding position of the positive and negative poles of the chip. Since one corner of the four-corner bracket is the positive pole, the first and third chips need to be placed in the second welding. The gold wire pulls the welding wire obliquely. When the wire welding machine moves at the same time in X and Y, the fish tail of the second solder joint is deformed, which reduces the firmness of the solder joint. With the advancement of LED chip technology, the brightness of the chip is improved, the size of the chip is reduced, the electrode of the chip is reduced, and the distance between the positive and negative electrodes of the chip is shortened, which requires a further reduction in the d...

AI Technical Summary

Problems solved by technology

The reduction of the diameter of the gold wire and the reduction of the caliber of the chopper will reduce the contact surface of the solder joint and the tension of the gold wire of the welding wire, so that there is a risk of the solder joint detaching at the fishtail of the second welding oblique welding, which will affect the LED lamp bead reliability

[0003] Most of the existing 3528 lamp bead bowls are round cups, and the position of the welding wire is relatively single, usually a gold wire oblique line. If it is not full, the pulling force of the second welding is insufficient, and the probability of failure will increase, which will cause dead lights after the finished product is made, and affect the life of the LED lamp bead.

At the same time, it will also have a certain impact on the life of the porcelain mouth, increasing production costs
