Last time, we have dicussed the feature of LED flex circuit, and this time, we will mention the way to make that Flexible circuit. 

1) The whole Flex circuit is the repeated of several section of FPC.

So we can populate LEDs, as well as ICs, etc, on FPC. And then solder each sections together, strip-by-strip, to make a long flex circuit boards.

After several strip of FPC is connected by soldering, or using connector, we will do testing and then packing them in a roll, normally 3 meter, or 5 meter. It should be packing in vacuum packing. 

  2) Just make the enough length single FPC one time, without the soldering connecting.

 This is used in some special end-products which obvious soldering is prohibitted and more strength is needed. Of course, this kind of FPC is more difficult to make, becuase of manufacuturing artwork & equipment limited.

Sometimes, poeple like to cut the customized lenght at his side according to different requirement.
