Problems solved by technology

At present, in the PCB of the LED lamp body, there are usually only gold-plated or silver-plated layers on the positive lead and negative lead. Although the silver-plated layer improves the luminous effect, the positive and negative electrodes on the PCB are easily oxidized by heat, resulting in a short service life of the LED

Abstract

The invention discloses a PCB for on-board integration of an LED. The PCB for on-board integration of the LED comprises the PCB, a positive plate and a negative plate, wherein the positive plate and the negative plate are arranged at the two ends of the PCB respectively; a positive electrode lead sheet is arranged on the positive plate and extends to the middle of the PCB; a negative electrode lead sheet is arranged on the negative plate and also extends to the middle of the PCB; the positive electrode lead sheet and the negative electrode lead sheet are respectively provided with a silver coating; the positive plate and the negative plate are respectively provided with gold plating. Compared with the traditional mode that electrodes and pole pieces of the PCB are provided with simplex plating, the PCB for on-board integration of the LED improves the light source effect of an LED lamp body, the stability of the PCB is enhanced, and the overall service life of the LED is prolonged.

Description

[0001] technical field [0002] The invention relates to a PCB, in particular to a PCB for integration on an LED board. Background technique [0003] PCB (Printed Circuit Board), also known as printed circuit board, printed circuit board, is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. Before the appearance of printed circuit boards, the interconnection between electronic components was achieved by direct connection of wires, but now, printed circuit boards have occupied an absolute dominant position in the electronics industry. According to the number of circuit layers, PCB is divided into single-sided board, double-sided board and multi-layer board. Common multi-layer boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach dozens of layers. Single-S...
