Help find oled display ffc connector

helmasur
helmasur over 7 years ago

I'm buying the "MCOT064032A1V-YI -  Graphic OLED, 64 x 32 Pixels" but what connector should i use on my pcb? For what I can tell the data sheet specifies 0.7mm between the pads on the ffc, but I fail to find a matching connector, am I doing this wrong somehow?

 

Any help greatly appreciated!

Regards

Martin

    Thanks a lot guys! It all makes sense now and I know what my approach will be. I will make my own very small 'break out' pcb that adapts from 0.7mm pads to a standard 0.1" header and solder the flex cable…

    Martin, That does not appear to be a standard FFC type cable. You are correct, there don't seem to be any connectors setup for that pitch (0.7mm). The PDF refers to a MPBV4-ISS2 adapter (see below) that…

    H Martin,

     

    Also if your particular display has conductors on both sides of the flat-flex, and through-holes in each of the pads at 0.7mm pitch, and if you're willing to experiment, then you can try just soldering it directly to the pads.

     

    The through-holes will be useful to conduct heat from the top side where your soldering iron will be, to the underside.

     

    What seems to work for me is to put down a small bit of solder paste on the PCB, and then place the flat flex in place, and then apply heat. If you do it carefully, the flat flex shouldn't melt, but don't hold me to it, I have not used the display you refer to. But the large 0.7mm pitch is often used for displays that can be soldered directly in this way I think.
