Description

Technical Field

[0001] The utility model belongs to the field of communication, and particularly relates to an improved structure of a butterfly laser backlight aluminum nitride thermal layer with high chip welding efficiency, low short circuit risk, low failure rate, simple operation and high efficiency. Background Art

[0002] Three views of the aluminum nitride thermal layer of the butterfly laser backlight (such as Figure 5 As shown), from top to bottom they are upward view, main view and downward view. From the main view, no gold-plated tin area is set, and the chip can only be fixed by glue. The operation is cumbersome and inefficient, and the fixation is not firm enough. From the downward view, the wiring area is on the left and on the right. When the pins are defined on the same side, they need to cross the gold layer, which can easily cause a short circuit, making it unsafe to use and having a high failure rate. From the upward view, no gold-plated area is preset, and the product can only be fixed by glue. The fixation is not firm, and it is time-consuming and labor-intensive, and cannot effectively meet the use requirements.

[0003] The technical problem to be solved by the utility model is to provide an improved structure of a butterfly laser backlight aluminum nitride thermal layer, which can directly weld and fix chips and products, has simple operation and high efficiency, saves time and effort, is firmly and reliably fixed, does not require pins to cross the gold layer, has a low risk of short circuit, has a high safety factor, and has a low failure rate, and effectively meets the requirements of use. Utility Model Content

[0004] In order to solve the problems of the above-mentioned prior art that the front end surface is not provided with a gold-plated tin area, the chip can only be fixed by glue, the operation is cumbersome and inefficient, the fixation is not firm enough, the wiring area is on the left and the right, when the pins are defined on the same side, they need to cross the gold layer, which is easy to cause short circuits, unsafe to use, high failure rate, no preset gold-plated area on the bottom surface, the product can only be fixed by glue, the fixation is not firm, it is time-consuming and labor-intensive, and it cannot effectively meet the use requirements, the utility model adopts the following technical solutions:

[0005] The utility model provides an improved structure of aluminum nitride thermal layer for backlight of butterfly laser, comprising a main body of rectangular structure, a gold-plated tin area with pre-set solder is arranged on one side of the front end face of the main body, the gold-plated tin area fixes the chip by welding, a lead gold layer on one side is arranged at the bottom corner on the right side of the upper end face of the main body, an L-shaped lead gold layer on the other side is arranged on the left side and extends to the upper right corner, and a welding gold-plated layer is arranged on the bottom end face of the main body for facilitating welding and fixing.

[0006] The beneficial effects of the utility model are: a gold-plated tin area is set on the front end surface and a gold-plated layer is added to the bottom surface, the chip and the product are directly welded and fixed, the operation is simple and efficient, time-saving and labor-saving, the fixation is firm and reliable, the lead gold layer adopts an L-shaped design, the pin wiring does not need to cross the gold layer, the short circuit risk is small, the safety factor is high, the failure rate is low, and the use requirements are effectively met.
