LED lamp band circuit board module containing multifunctional aluminum foil, and manufacturing method

Abstract

The invention relates to an LED lamp band circuit board module containing a multifunctional aluminum foil, and a manufacturing method. Specifically, the back surface of a single-sided flexible circuit board is gelatinized; tin-conducting holes are punched by a die; then the positions, corresponding to the tin-conducting holes, of the back surface are covered with a metal back line, wherein an easily-tin-welded metal is at least on the surface of the metal back line; the metal back line is exposed out of the tin-conducting holes in the front surface of the single-sided flexible circuit board; the back line is covered with and packaged by multiple aluminum foil bands at certain spacings, wherein the width of the aluminum foil bands is greater than that of the back line; meanwhile, the aluminum foil bands are tightly glued by adhesive on the two sides of the back line for tightly clamping the back line in the middle to be contacted and conducted; element welding in an SMT patch manner is performed; the back line and a front surface circuit are welded together in the positions of the tin-conducting holes to enable the aluminum foil on the back surface, the metal back line, and the front surface circuit to be mutually conducted together to prepare the LED lamp band circuit board module containing the multifunctional aluminum foil. By virtue of the LED lamp band circuit board module and the manufacturing method, the problem that it is quite hard to realize connection and conduction between an aluminum circuit on the lamp band and a copper surface circuit is solved.

Description

technical field [0001] The invention relates to the application fields of circuit boards and LEDs, in particular to a circuit board module and a manufacturing method of an LED strip made of multifunctional aluminum foil. Background technique [0002] LED light strip circuit board The circuit board of the prior art, because aluminum cannot be soldered, has not used cheap aluminum for the circuit. The conduction between them is not solder conduction, but is conducted by manually winding thin wires one by one, with high efficiency and low cost. [0003] In addition, since the LED light strip usually has a periodically set shear position, it will be cut at the shear position according to the need during use. The voltage safety regulations stipulate that the light strip circuit board has not been able to use cheap aluminum foil instead of expensive PI as the cover film to protect the back circuit, and the light strip circuit board has not been able to use aluminum foil instead o...

[0002] LED light strip circuit board The circuit board of the prior art, because aluminum cannot be soldered, has not used cheap aluminum for the circuit. The conduction between them is not solder conduction, it is conducted by manually winding thin wires one by one, with high efficiency and low cost

[0003] In addition, since the LED light strip usually has a periodically set shear position, it will be cut at the shear position according to the need during use. The voltage safety regulations stipulate that the light strip circuit board has not been able to use cheap aluminum foil instead of expensive PI as the cover film to protect the back circuit, and the light strip circuit board has not been able to use aluminum foil instead of PI as the base material to make aluminum-based flexible boards with high heat dissipation. And then made into a high heat dissipation aluminum base flexible LED strip
