Extending FFC Cables...

Hi there,

I have a very short 24pin 0.5mm pitch FFC cable which I hope to extend using a FFC Jumper cable.

I did a search on best ways to do this:

1. MANUALLY SOLDER (Difficult)

http://forum.allaboutcircuits.com/showthread.php?t=43394) --> I really hope to avoid this as I have REALLY bad soldering experience.

2. Buy a Extension circuit board (hard to find in 24pin) http://www.ebay.com/itm/40Pin-to-40Pin-ZIF-0-5mm-connector-adapter-with-extension-flat-cable-FFC-extend-/360622317055 --> I know the above is 40pin. But would it not be possible to just slot in a 24pin (so i don't really use the remaining pins), as long as the "pitch" is correct? This would be great since 24pin version is unavailable.

3. Use a normal FPC adaptor to compress two FFC ends together?? http://kyorune.com/modding/article.php?id=63 --> This seems like the simplest and easiest way... But is it really THAT simple? Buy a 24pin adaptor, and stuff two FFC ends inside and clamp it down?

Appreciate any comments / help.

Thanks!!

Why not buy correct length cable?

The long 24pin 0.5mm pitch FFC cable come with 100 mm, 150 mm, 200 mm, ... 450 mm, 500 mm. How long do you want?

When you deal with FFC cable, make sure which type you need;-

top is standard, and bottom is reversed. longer than 500 mm is needed custom made and might have MOQ (minimum order quantity).

Hi Sonnyyu, thanks for the tips!!

The problem is I am extending a CMOS sensor, which already has a 50mm FFC directly soldered to it.

I need to extend to 150mm.

I understand why you do not replace the cable.

Desoldering tools and materials include the following:

  • Solder wick
  • Heat guns, also called hot air guns
  • Desoldering pump
  • Removal alloys
  • Removal fluxes
  • Heated soldering tweezers
  • Various picks and tweezers for tasks such as pulling at, holding, removing, and scraping components.
  • Vacuum and pressure pumps with specialized heater tips and nozzles
  • Rework stations, used to repair printed circuit board assemblies that fail factory test.

Removal alloys might help you remove the cable from CMOS sensor.
