Sudden failure (LED not to illuminate) are most often caused by disconnecting failure at solder-point on FPC (flexible printed circuit) due to mechanical stress. The length of one FPC is generally 200mm. It means 25pcs of FPC are needed to joint (solder joint) to make 5000mm led strip. That’s obvious it’s hard and weak to bend at the area where soldering joint. If it’s tightly bent, it leads to disconnection problem occurred at soldering joint area due to applying mechanical stress. It causes failure (LED not to illuminate).
How ATEX solved it? We developed ATEX long flexible printed circuit board technology (seamless long FPC) and production devices to solve the issue.
Here is our development story. As FPC we were looking for did not exist on the market, ATEX and FPC manufacturer had jointly developed a “long seamless FPC”. In addition to the long seamless FPC, we needed an automated Reel to Reel (R2R) production process and right devices to ensure proper operation to fit in dozens of meters of the seamless FPC. The devises were also required to mount an electronic part continuously and solder accurately to match such a long length of FPC. The production devises were developed in-house to adapt to the FPC. Finally, we developed combination of proper devises and Reel to Reel (R2R) production process which is compatible with the seamless FPC.
These seamless FPC technology and devises including Reel to Reel production process make it possible for us to produce dozens of meters of long flexible LED strip continuously all at once.
In summary, ATEX long flexible printed circuit board (seamless FPC) technology can overcome weak points in general FPC. 1. Minimize disconnecting failure (no soldering point on FPC). 2. More durable against bending force 3. Improve productivity (reduce assembly cost, shorten lead time) by developed devise and automated Reel to Reel production process |
