CSP flexible light strip intelligent automatic production line

Three major process advantages and production line parameters of CSP packaging flexible light strip automatic production line:

1. Reduce material costs: Compared with traditional SMD and COB packaging methods, the CSP packaging method of Guangshengde flexible light strips eliminates the process of packaging the wick to the bracket, directly saving customers 30% of raw material and processing costs;

2. Reduce labor costs: Compared to the existing SMD and COB production methods (which can only operate PCB boards of about 0.5 meters or 1 meter), the production line substrate of Guangshengde's online flexible light strip CSP packaging method can reach several hundred meters or longer, without the need for manual welding after production, saving all welding costs. Save 90% of labor costs;

3. Improving production efficiency and product qualification rate: Guangshengde's online flexible light strip CSP packaging method has shifted from offline operation to fully automated online operation, with little need for manual operation. The product defect rate has been reduced from 3% to 0.03%, greatly improving production efficiency and product yield! It is a disruptive technological revolution in SMD and COB packaging methods;

Introduction to CSP flexible light strip production process

The existing LED strips coated with fluorescent adhesive have a rectangular coating shape or are not coated with fluorescent adhesive, resulting in insufficient LED emission angle and direction, blue light leakage, and poor applicability.

In response to the shortcomings of existing technology, the production process of CSP flexible LED strip aims to create a CSP packaged LED strip with a wide light emission angle and direction, no blue light leakage, and a simple structure.

Provided is an LED strip based on CSP packaging, comprising a sealed soft gel and an LED light source strip, wherein the sealed soft gel wraps around the LED light source strip; The LED light source strip includes a flexible FPC circuit board, CSP, and coating layer; The flexible FPC circuit board is strip-shaped, and the first surface of the flexible FPC circuit board is provided with multiple positive and negative electrode solder joints arranged along the length direction of the flexible FPC circuit board. Each positive and negative electrode solder joint is soldered with a CSP; The flexible FPC circuit board also includes multiple soldering boards arranged at or between the two ends of the flexible FPC circuit board; The coating layer is a hemispherical lens that covers each CSP separately, or a circular arc-shaped packaging strip that extends along the length direction of the flexible FPC circuit board and covers multiple CSPs.
