Embodiment 1

[0030] The production process of a small-sized LED copper strip in this embodiment is an H65 LED brass strip with a thickness of 0.11 mm, its surface roughness is less than 0.12 um, its Vickers hardness is 145-160, and the H65 composition is: copper Cu: 63.5~68.0; zinc Zn: balance; lead Pb: ≤0.03; lead Pb: ≤0.03; boron P: ≤0.01; iron Fe: ≤0.10; Between H68 and H62, the price is cheaper than H68, can withstand cold and hot pressure processing well, and has a tendency of corrosion and cracking.

[0031] A small-scale LED copper strip production process, the steps are as follows:

[0032] (1) Melting ingot; (2) Hot rolling; (3) Face milling; (4) Rough rolling, wherein the specified thickness of the coil after rough rolling is 2.0mm; (5) Primary annealing; (6) Primary cleaning (7) Middle rolling; (8) Secondary annealing; (9) Secondary cleaning; (10) Middle finishing rolling; (11) Three times annealing; (12) Three times cleaning; (15) Four times of annealing; (16) Four times of w...

Abstract

The invention discloses a small-size LED copper strip production process, and belongs to the technical field of the copper strip production process. The production process includes the following stepsof (1) smelting and ingot casting, (2) hot rolling, (3) milling, (4) rough rolling, (5) first annealing, (6) one-step cleaning, (7) intermediate rolling, (8) secondary annealing, (9) secondary cleaning, (10) intermediate finish rolling, (11) third annealing, (12) third cleaning, (13) finish rolling, (14) unwinding, (15) fourth annealing, (16) fourth cleaning, (17) refine rolling, (18) fifth cleaning, (19) flattening and (20) cutting and delivery. According to the technical scheme, the quality of small-size LED copper strips can be improved, the workshop cost is reduced, and the production profits are increased.

Description

technical field [0001] The invention relates to the technical field of a copper strip production process, in particular to a production process for a small-sized LED copper strip with a thickness of 0.11 mm. Background technique [0002] The LED lamp bracket is the bottom base of the LED lamp bead before packaging. On the basis of the LED lamp bracket, the chip is fixed in, the positive and negative electrodes are soldered, and then packaged with packaging glue. LED light brackets generally use copper as the base material, because copper has good conductivity, and other metals such as silver are plated on the surface of the copper strip to facilitate welding and packaging. There will be leads inside it to connect the electrodes inside the LED lamp beads. After the lamp bead is packaged and formed, the lamp bead can be removed from the bracket, and the copper feet at both ends of the lamp bead become the positive and negative electrodes of the lamp bead, which are used for we...
