Q: (18509)

Hello Caig,

In the attached picture are the 2 connectors which give me troubles – loots of intermittents.
Attached you’ll find the datasheet for the IDC connectors on the black PCB and the wide ribbon cable, Unfortunately, I don’t have any datasheet for the 2 x 17 connector used to stack the 2 smaller boards (which BTW gave me most of troubles).
For what is worth, visually the contacts surface seems to be quite similar to the contacts of the IDC connectors.

Looking forward to your comments.

Best regards,

Hello Max,

I would use the DeoxIT® D100L-2DB. This should solve the intermittent issues. Any oxidation on the pins could create the signal interruptions.
Wipe the pins and insert into the socket. The DeoxIT® will clean and treat both surfaces.
