FFC cable for laptop motherboard - measuring pitch

Interconnect Cable Assemblies

Hi,

I am tying to replace a laptop internal cable that has gone bad. I know it is FFC, but unsure about the type and size since I am unsure where to measure the pitch on it.

I am including a picture of it in case someone know what I am looking for or how to measure the pitch (the cable has several different widths).

On the cable is printed:
from laptop manufacturer:
DYG60_PS_FFC
NBX0001KE10 0A

From the ribbon itself:
60V VW1 HE 80C

Thanks in Advance!

Hello Greg, welcome to the forum!

Pitch would be measured from the center of one conductor to the center of the conductor next to it. I could take my best shot at a measurement if you could put something next to it that would be a standard size, like a ruler or a coin, in the photo.

Yes welcome Greg.
See the link below of how to measure a flat flex cable.

Hi Justin,

Thanks for the assist. My (cheap) caliper will not do sub millimeter, so I am close, but not exact.

In the pic (10 cents):
yellow - 3mm (very close)
green - between 2 and 3 :slight_smile:
blue I cannot measure as my (cheap again) caliper closes on it and it folds.

Thanks!

Thanks Chris,

I had read that from the forums before I posted, but with the connector and ribbon widths differing so much, I did not know what width to use to measure it. If the pic I posted gives no insight, I will buy a better caliper I guess :slight_smile:

Hi Greg. Thanks for the photo! From the measurements I took, the cable appears to be a 0.5mm pitch. If you were going to go with the version described above, you would go with the green line. The cables I could find in our system with the 0.5mm pitch and 5 conductor are all straight end, rather than tabbed, so they may not latch into the connector on the board, but they can be found on the following link:

Thank you very much!

From looking at my existing cable, if I am careful, the tab peels off and I can probably adhere it to the new cable to fit in the connector.

Thanks Again!

I’ll order a couple in case I mess one up :slight_smile:
