\$\begingroup\$

Two led tapes of width ~1cm sit 1cm apart. Between them in the middle, there's an obstacle around 3mm thick. I want to connect the LED tapes with a flexible cable that goes around the obstacle. FFCs come to mind, but I'm not sure what's best. Do you have any ideas for alternative approaches? I discovered JST FFC Connectors in the Similar Questions section before making this post. Would a JST FFC approach be relatively feasible in a DIY project? Ideally, the cable should snap in and be easy to disconnect, in order to make the tape pieces modular and easy to replace. My LED tape is a bit dense (144 LEDs per meter) and has 3 pins as shown in the image. I may have to do something about the limited length on the edges, but my main concern is picking the right cable/connector approach.

(And apologies for the low-res picture & bad soldering)

As you can see, using regular wire takes up too much space.

    \$\begingroup\$ How much current must pass the wiring over the 1cm gap? BTW, this is too large scale for being classified as microelectronics, and usually electrical things are soldered, not welded. \$\endgroup\$

  • \$\begingroup\$ I edited the post. Using wire takes up too much space and the solder metal isn't shock-proof, although this probably also has to do with the solder itself. It sticks fine to the surface but if I bend the wires, some of the force causes them to come off. As for the current, maybe this datasheet helps: cdn-shop.adafruit.com/product-files/2757/… The aliexpress listing no longer exists but the title had "SK6812 RGBW" and "Similar WS2812B" so, it should be the SK6812 RGBW. \$\endgroup\$

  • \$\begingroup\$ run separate power wires in parallel with the LED strips ... attach thinner drop connections to each LED strip section ... the data connections can use thin wire \$\endgroup\$
