Embodiment

[0053] The LED neon strip processing technology disclosed by the present invention mainly includes seven steps of SMT patching, welding FPC soft board, aging impact, processing before extrusion, extrusion, glue dispensing and test packaging.

[0054] 1. SMT patch

[0055] The overall process: Use a solder paste printing machine to print high-temperature lead-free solder paste on the FPC soft board; then use a placement machine to paste LED lamp beads and other auxiliary components on the FPC soft board printed with solder paste; The FPC flexible board after the chip is reflow soldered by a reflow soldering machine; finally, use a test tool to test whether the semi-finished product after reflow soldering is qualified, and mark it before it can flow to the soldering process. Concrete process steps are as follows:

[0056] 1. Inkjet code: Use the inkjet printer to print the identification code on the back of the FPC soft board.

[0057] 2. Solder paste printing:

[0058] (1) S...

Abstract

The invention discloses an FPC-based silica gel extrusion molding adhesive dispensing LED neon light belt processing technology. The technology comprises the following steps that a, LED light beads and other parts are pasted on an FPC soft board, and reflow welding is conducted; b, the FPC soft board is welded into a long board in a lead-free manual welding mode; c, the FPC soft board welded into the long board is subjected to ageing impact; d, the qualified FPC soft board obtained through ageing impact is subjected to pre-extrusion-molding machining; e, the FPC soft board is subjected to extrusion molding through solid silica gel matched with an extrusion mold, and solidification is conducted through a baking oven; f, adhesive is dripped into a groove of the extrusion-molded FPC soft board twice, bubbles are removed through a heat air gun, and then baking solidification is conducted; and g, a semi-finished product in the step (6) is cut short from the connection piece position of the semi-finished product, a plug is installed, and processing is completed. Through the process, waterproofness, moisture proofness, luminance uniformity and color-temperature consistency of an LED neon light belt can be effectively ensured, and very high practical value is achieved.

Description

technical field [0001] The invention relates to a neon light strip, in particular to an FPC-based processing technique for extruding and dispensing LED neon light strips with silicone. Background technique [0002] With the popularization of the application of LED lamps, the finished forms of LED lamps have also shown various forms. Some high-end LED products have gradually shifted from hard LED lamp products to bendable soft lamp products. LED neon strips are one of them. A representative product form. The LED neon light strip mainly includes a casing and a circuit board. Electronic components and LED lamp beads are installed on the circuit board. The entire casing must be well sealed to ensure waterproof and moisture-proof effects. It is also necessary to be able to meet the requirement that the neon light strip can be bent, and the conventional processing technology is difficult to meet the technical indicators of the LED neon light strip.
