Embodiment Construction

[0040] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements.

[0041] see figure 1 As shown, the present invention provides a kind of manufacturing method of embedded light-emitting diode (LED) circuit board, and this manufacturing method comprises the following steps:

[0042] S11, forming a through hole on a circuit substrate, and the through hole communicates with a first surface and a second surface opposite to the circuit substrate;

[0043] S12, embedding an LED in the through hole of the circuit substrate; and

[0044] S13, connecting the two pins of the LED with a circuit on the second surface of the circuit substrate.

[0045] When actually manufacturing embedded LED circuit boards, multiple circuit substrates are arranged in a matrix, and the processing operations of these circuit substrates are performed simultaneously to save production time. Each of the circuit subst...

Abstract

The invention discloses an embedded light emitting diode (LED) circuit board and a manufacturing method thereof. The manufacturing method comprises a step of forming a hole in a circuit substrate, wherein the hole communicates with opposite first surface and second surface of the circuit substrate, a step of burying an LED in the hole of the circuit substrate, and a step of connecting two pins of the LED and a line on the second surface of the circuit substrate. Compared with prior art, since the LED is arranged in the hole of the circuit substrate and is not arranged at the surface of the circuit substrate, thus the LED is embedded into the circuit substrate, the thickness of the LED circuit board is reduced further, and the installation of the LED circuit board in an electronic device with a limited volume is facilitated.

Description

technical field [0001] The invention relates to a circuit board and a manufacturing method thereof, in particular to an embedded light-emitting diode circuit board and a manufacturing method thereof. Background technique [0002] see Figure 8 As shown, when installing a light-emitting diode 60 (LED) on the circuit board 50 of the prior art, the circuit board 50 is formed with two through holes 51 earlier, and the LED60 is arranged on the top surface 52 of the circuit board 50. The LED60 The two pins 61 respectively penetrate the two through holes 51 from the top surface 52 of the circuit board 50, extend out from the bottom surface 53 of the circuit board 50, and then bend and weld with the circuit 54 on the bottom surface 53 of the circuit board 50. In this way, the LED 60 is disposed on the top surface 52 of the circuit board 50 , and the LED 60 can be electrically connected to the circuit 54 on the bottom surface 53 of the circuit board 50 to be energized and emit light....
