I now want to connect 18032 ultrasonic module with 18003 interposer via FPC purchased from your shop. however, i do not know how to make stable the connection since the cable is soft and it is hard to keep connected. I’ve noticed a lock printed on pcb. I am wondering how can I use it to secure the connection? Thanks!
Hi @ethanlyu ,
The connection should be pretty stable using the FPC. You have to insert it while the locking mechanism is open. Here’s an image to illustrate:
Then you have to lock it back and create a stable connection.
Thanks for ur response. There is an arrow indicating lock direction (up 
︎), which is opposite to to the upper description. On the other hand, I have to press one of the endpoints to make it connected (press down) manually and it will loosen if I don’t press it continuously. I am wondering how can secure the lock.
Hi @ethanlyu ,
Here’s my setup and they are pretty secured. Could it be a connector issue? When I pressed the black plastic for locking, it latches and stays locked.
