Abstract

The invention discloses a four-pin 3528 LED lamp welding pad, which comprises a first pin welding pad, a second pin welding pad, a third pin welding pad, a fourth pin welding pad, a first copper sheet connected with the first pin welding pad, a second copper sheet connected with the second pin welding pad, a third copper sheet connected with the third pin welding pad, and a forth copper sheet connected with the forth pin welding pad, wherein the first copper sheet, the second copper sheet, the third copper sheet and the fourth copper sheet form an oval shape; a gap exists between adjacent two copper sheets; and the gap between the two pin welding pads at 35 edges is larger than the gap between the two pin welding pads at 28 edges. The four copper sheets form an oval shape, the occupied space of the welding pad is saved as much as possible on the premise of ensuring cooling, more wiring or via positions can be avoided, and the relationship between wiring and cooling can be effectively considered.

Description

technical field [0001] The invention belongs to the application field of LED electronic equipment, and in particular relates to a welding pad of a four-pin 3528 LED lamp. Background technique [0002] At present, in the design of some high-power PCB boards, heat dissipation is the most concerned issue. In the process of PCB wiring, it is necessary to consider not only the size of the current, but also the heat dissipation problem, and also the radiation problem. Therefore, , in PCB wiring, the reasonable layout of the power ground determines the quality of the product to a large extent. The heat dissipation of the power ground on the PCB generally adopts the method of covering a large area with copper, so that the heat can be dissipated quickly, and at the same time, the large area of ​​copper can be Make sure enough current flows through. In order to facilitate wiring, the wiring personnel use a large area of ​​copper to completely cover the power ground pad of the IC. Thi...
