Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0043] figure 1 It is a structural schematic diagram of the existing PPA+copper pin package bracket, figure 2 It is a schematic diagram of the structure of the existing CHIP type packaging bracket, all of which are single package structures. In actual production, with the shrinking of the pixel pitch of the LED display, the number of packaged devices per unit area is increasing. Therefore, the used The number of LED packaging devices is huge, and the production efficiency is extremely low by only relying on the production method of single mounting.
[0044] see Figure 3-Figure 17 , are various embodiments of the surface-mounted RGB LED integrated substrate provided by the present invention. The substrate 1 provided by the present in...

The invention provides a surface mounting type RGB-LED integrated substrate and a manufacturing method thereof. A plurality of luminous zones are arranged on the front face of the substrate. Each luminous zone is provided with four mutually independent upper welding discs used for die bonding welding wires. The upper welding discs are provided with up-down-through metal holes penetrating through the substrate. The positions, corresponding to the metal holes, of the reverse face, of the substrate are provided with lower welding discs. The substrate is provided with cutting lines used for dividing the substrate into a plurality of packaging modules provided with a plurality of luminous zones. Electroplating circuits are arranged in the positions of the cutting lines. The widths of the cutting lines are larger than the widths of the electroplating circuits. The upper welding discs are in electric connection with the lower welding discs through the electroplating circuits. According to the surface mounting type RGB-LED integrated substrate and the manufacturing method thereof, electroplating of all the welding discs is completed, a plurality of RGB-LED lamp beads are integrated in one packaging module, thus LED production efficiency in subsequent application and production is improved greatly, and production cost is reduced greatly.
Description
technical field [0001] The present invention relates to SMD (Surface Mounted Devices, surface mount device) LED packaging technology, in particular to a surface mount RGB LED integrated substrate and a manufacturing method thereof. Background technique [0002] Compared with other display technologies, LED display has the advantages of self-illumination, excellent color reproduction, high refresh rate, power saving, and easy maintenance. The fundamental factor of rapid growth, in the field of super large screen outdoor display, currently there is no technology that can compete with LED display. Small-pitch LED displays generally refer to LED displays with a dot pitch of less than 2.5mm. Because small-pitch LEDs have the advantages of no seams, good display effects, and long service life, and the cost has dropped rapidly in recent years, they have gradually replaced indoor displays. The price basis of large-screen video walls will gradually enter the commercial and even civi...
