You need to look for "card edge onnectors" like these: [https://lcsc\.com/product\-detail/Card\-Edge\-Connectors\_UMAX\-M42F\-08P\-020\-P002G\_C404107\.html](https://lcsc.com/product-detail/Card-Edge-Connectors_UMAX-M42F-08P-020-P002G_C404107.html)<br> <br> but before you can choose a specific connector that is suitable you need to measure: * the pitch and * width of the pads on this flexi connector cable and * the length of the pads and * the thickness of the flexi between the top and bottom layer of the end with those pads on. * You also obviously need to know what the function of each pad is and * how many pads there are on each side (top and bottom of the flexi).

Thanks. I'll wait them to arrive to make the details,. I'd just like to search for them here and make a previus PCB so that when it arrives, I would just adjust, because I'm very new on making these PCBs and understand terminology. But I can answer twoof the questions right away: * only for pads on one side.  * Funcion of the pads: run a mini bipolar stepper motor (A+, A-, B+, B-).
