− | {{traduction}} | + | === About the FPC connector === |
| + | |
| + | The selected FPC connector us the "Press Fit" technology which is resistant to traction and vibration. Such connectors can even been definitively locked with some glue. |
| + | |
| + | This means than once the ribbon right in place into the connector, you press down the locker to fit/secure the ribbon. |
| + | |
| + | [[Fichier:FPC-connector.jpg|480px]] |
| + | |
| + | Once secured, the ribbon will not move without releasing the lock. |
| + | |
| + | As show on the section of the connector here under, the ribon is inserted into the connector with contact facing the contact point. |
| + | |
| + | When the moving part is inserted behind the ribon, the ribon contact are pressed onto the contact points. Points that also firmly maintain the ribbon right in place. |
| + | |

| + | |
| + | === How to manipulate the FPC Connector === |
| + | |
| + | The lock slides of 1 millimeter up. |
| + | |
| + | 1mm is not a lot but quite enough to secure the ribbon in place. |
| + | |
| + | [[Fichier:How-to-manipulate-FPC.png|640px]] |
| + | |
| + | {{ambox-stop|text=The FPC connector is not designed for intensive opening/closing operations (~30 times) but to firmly secure a connexion during a final assembly phase. Only remove the ribbon from the connector when absolutely necessary!}} |
| + | |
| + | === Attaching the board === |
| + | |
| + | When connecting the ribbon, the electrical contact must be oriented downward. |
| + | |
| + | [[Fichier:Cansat-Attaching-Boards.jpg|640px]] |
| + | |
| + | Ribbon must be inserted straight in the FPC connector |
| + | |
| + | [[Fichier:Cansat-Attaching-FPC-01.png|640px]] |
| + | |
| + | Both side of the of the connector must be pressed down to secure the ribbon. |
| + | If now properly closed, some signals will not be shipped on the ribbon. |
