LED lamp, bendable aluminum-based printed circuit board, manufacturing method and application

Abstract

The invention discloses an LED lamp, a bendable aluminum-based printed circuit board, a manufacturing method and application, and relates to the technical field of printed circuit board manufacturing. The manufacturing method comprises the following steps: cutting a single-sided aluminum substrate; performing outer layer pattern processing, outer layer etching, target hole drilling, solder mask, character manufacturing, and performing blind groove processing on the aluminum surface after solder mask; and after the blind groove is machined, carrying out forming. The bendable aluminum-based printed circuit board for the LED comprises a single-sided aluminum substrate, an auxiliary pattern, an auxiliary positioning hole, a solder mask, a character, a first blind groove and a second blind groove. The aluminum substrate is a single-sided aluminum substrate, and the bending difficulty is reduced by reducing the thickness of a bending area by milling the blind groove in the hole depth of the back surface of the aluminum substrate; and the pressing process of adopting a soft plate, pure glue and an aluminum plate is avoided, the processing difficulty and the processing time are greatly reduced, and meanwhile, the material cost can be greatly reduced by purely adopting the aluminum plate. Compared with the prior art, the invention finds a new way, the process manufacturing flow is simpler, and the quality control point is simpler.

Description

technical field [0001] The invention belongs to the technical field of printed circuit board manufacturing, and in particular relates to an LED lamp, a bendable aluminum-based printed circuit board, a manufacturing method and an application thereof. Background technique [0002] At present, LED lights have the characteristics of good monochromaticity, bright and rich colors, long life, good shock resistance, no delay in lighting, fast response time, low energy consumption, small size and light weight. [0003] In the field of car lights, with metal base, its heat dissipation power has been greatly improved. With the rapid development of automobiles, various designs have appeared, including the three-dimensional assembly of multiple low-power LEDs instead of a single plane assembly. High-power LEDs not only improve brightness, but also reduce power consumption caused by high-power LED heat. [0004] At present, the bendable aluminum-based printed circuit board structure in t...

AI Technical Summary

Problems solved by technology

[0006] Conventional three-dimensionally installed aluminum-based printed circuit boards use soft board + pure rubber + aluminum-based reinforcement to achieve bending. The production process is long and complicated, and the cost is high.

[0007] The difficulty of solving the above problems and defects is: At present, the industry can only realize bending through soft board, pure rubber, and aluminum-based reinforcement, and there is no other manufacturing method to achieve bending
