With the application of LED diffuse reflection light strips (rolling shutter) in the field of advertising light box backlighting more and more popular, coupled with the smaller and smaller size of the single LED package, the higher the power and the higher the brightness , LED diffuse reflector light strip (roller shutter type) came into being. Its ultra-high brightness coupled with the appropriate lens makes it possible to use only 4-5 light strips for a square meter of light box backlight, which greatly reduces the diffuse reflection of light box LEDs.

Nowadays, LED injection molding modules are widely used, mainly in the following three points 1. Advertising signs, lighting signs, (ultra-thin) light boxes, three-dimensional luminous characters, blister characters, other advertising lighting, etc.; 2. Hotel, KTV, shopping malls, entertainment city interior (dark slot), exterior wall lighting, landscape layout, stage decoration, urban lighting, etc. 3. Home shoe cabinets, wardrobes, hidden ceilings, showrooms

Introduction to the manufacturing process steps of LED injection molding module 1. Microscopic inspection of LED injection molding module chips: whether there is mechanical damage and pitting on the surface of the material, whether the chip size and electrode size meet the process requirements and whether the electrode pattern is complete. 2. LED injection molding module expansion, because the LED injection molding module chips are still closely arranged after dicing and the spacing is very small (about 0.1mm), which is not conducive to the subsequent process.

The LED injection molding module is a solid-state semiconductor device. The heart of the LED injection molding module is a semiconductor wafer. One end of the wafer is attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire wafer is epoxy resin encapsulated. Also known as LED injection molding module light-emitting chip, it is the core component of LED injection molding module, which is the P-N junction. Its main function is:

The research on ABS engineering plastics, raw materials for LED injection molding modules, began in the 1960s and has developed rapidly in recent years. According to statistics, the total consumption of plastic alloys (including modified resins) in my country is about 1.2 million to 1.4 million tons, while the domestic supply is less than 600,000 tons, and the annual import volume is as high as 900,000 tons; and my country's LED injection molding module raw materials ABS engineering plastics (mainly blended resins and modified
