Embodiment

[0046] 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 molding, extrusion molding, and test packaging.

[0047] 1. SMT patch

[0048] 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:

[0049] 1. Inkjet code: Use the inkjet printer to print the identification code on the back of the FPC soft board.

[0050] 2. Solder paste printing:

[0051] (1) S...

Abstract

The invention discloses a process for machining silica gel extrusion flexible lamp strips. The process includes steps of a, adhering LED lamp beads and other components on FPC (flexible printed circuit) boards and carrying out reflow welding; b, welding the FPC boards to obtain long boards in lead-free manual welding modes; c, carrying out aging impact on the FPC boards which are welded to obtain the long boards; d, carrying out extrusion pre-machining on the FPC boards which are qualified during aging impact; e, carrying out extrusion on the FPC boards by the aid of solid silica gel mixtures and extrusion dies which are matched with one another, and curing the FPC boards by the aid of baking furnaces; f, cutting semi-finished products obtained at the step (e) from connecting sheets of the semi-finished products to shorten the semi-finished products and mounting upper plugs to completely machine the silica gel extrusion flexible lamp strips. The process has the advantages that the waterproof and damp-proof performance, the luminance uniformity and the color temperature consistency of the LED flexible lamp strips can be effectively guaranteed, and accordingly the process has extremely high practical value.

Description

technical field [0001] The invention relates to a neon light strip, in particular to a processing technology of a silicone extruded soft light strip. 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. Contents of the invention [0003] The object of the present in...
