Problems solved by technology

The traditional board surface lamp bead board is made of traditional deep control panel, which removes the side wall of the panel surface lamp bead board through the conventional board method, so as to realize the vertical segmentation of the side wall; and the current side wall lamp bead board It cannot be realized by the conventional gong plate or drilling production method, and its quality requirements and production process requirements are relatively difficult, so the production process needs to be changed to meet customer requirements

Embodiment Construction

[0014] The method for manufacturing a horizontally segmented PCB with a metallized side wall for a display screen according to the present invention will be further described in detail below in conjunction with specific embodiments.

[0015] A PCB manufacturing method for horizontally segmented metallized side walls for display screens, including substrate manufacturing, after the substrates are manufactured, two substrates that have been manufactured are selected, and horizontal segments are placed between the two substrates A segmented layer of grooves, said segmented layer being pressed together with the upper and lower substrates. Specifically, the production of the substrate includes material cutting→drilling→forming and slotting→plate circuit→outer layer graphics→graphic circuit→secondary drilling→etching→external inspection. The same production method is used for two productions to obtain L1 / L2, After the L3 / L4 layer, L1 / L2, and L3 / L4 layers are manufactured, use a gong...

Abstract

The invention relates to a method for manufacturing a PCB with horizontally segmented metallized side walls for display screens, including substrate manufacturing. After the substrates are manufactured, two substrates that have already been manufactured are selected, and two substrates are arranged between the two substrates for manufacturing. A segmented layer of horizontally segmented grooves, said segmented layer being pressed together with the upper and lower substrates. The method for manufacturing the horizontally segmented PCB of the metallized side wall for the display screen of the present invention has the advantages of high production efficiency, good quality, and the like.

Description

technical field [0001] The invention relates to the technical field of circuit board production, in particular to a PCB production method with horizontally segmented metallized side walls for display screens. Background technique [0002] LEDs will be widely used in stadiums, cities and public squares, transportation, corporate image promotion, commercial advertisements and other applications. Due to the long viewing distance and high ambient brightness of sports venues, only LED displays can meet this special requirement, ensuring that the audience can obtain clear and vivid color images, and bringing unlimited visual enjoyment to the audience. The precision requirements of the PCB are getting higher and higher, and the previous board surface lamp bead board is converted into a board side wall lamp bead board. The traditional board surface lamp bead board is made of traditional deep control gongs, which remove the side wall of the board surface light bead board through the...
