Problems solved by technology

However, the inaccurate position of the part may cause the LED to be skewed or shifted during the process of bonding; during the reflow process, the melting of the solder will also cause the LED to drift, resulting in the position of the LED that has been surface-mounted. Often it becomes messy, which fails to meet the customer's standards and affects the overall performance of the finished light bar

Embodiment Construction

[0034] See figure 1 , the LED light bar provided by an embodiment of the present invention includes LEDs 10 and a circuit board 20 carrying the LEDs 10 .

[0035] The light-emitting diode 10 is a light-emitting diode packaging structure, which includes a substrate 11, an electrode 12 disposed on the substrate 11, a light-emitting diode chip 13 mounted on the substrate 11, and a packaging layer covering the light-emitting diode chip 13 on the substrate 11 14.

[0036] The base plate 11 is roughly plate-shaped, and a first clamping portion is disposed on a lower surface thereof. In this embodiment, the first locking portion is a protrusion 15 extending downward from the lower surface of the substrate 11 , and the size of the protrusion 15 gradually decreases downward from the lower surface of the substrate 11 . The protrusion 15 has at least one inclined surface 151 inclined relative to the lower surface of the substrate 11 . In this embodiment, the cross-sectional shape of t...

Abstract

A light-emitting diode light bar comprises a light-emitting diode and a circuit board bearing the light-emitting diode. The lower surface of the light-emitting diode is provided with a welding spot, an anti-welding layer is coated on the circuit board, a first clamping portion and a second clamping portion are arranged between the light-emitting diode and the anti-welding layer, and the second clamping portion can be used for clamping and positioning the first clamping portion. Therefore, the influence of deflection or deviation of the light-emitting diode in subsequent operation on the performance and the like of a finished light-emitting diode light bar can be avoided. The invention further relates to a manufacturing method for the light-emitting diode light bar.

Description

technical field [0001] The invention relates to a semiconductor structure, in particular to a light emitting diode light bar and a manufacturing method thereof. Background technique [0002] Compared with traditional light sources, light emitting diodes (Light Emitting Diode, LED) have the advantages of light weight, small size, low pollution, long life, etc. As a new type of light source, they have been more and more widely used. [0003] Existing LED light bars generally include a circuit board and a plurality of LEDs located on the circuit board. The bottom surface of the LEDs is flat, and solder joints are protruded on the bottom surface. To make the light emitting diode light strip, the light emitting diode is electrically connected to the circuit board by using the surface mount technology. In this process, the solder paste is generally first applied to the solder joints on the lower surface of the LED, and then the LED is placed on the circuit board by a punching mac...
