Connectors for connecting traces on one or more flexible circuit boards to traces on a printed circuit board. These connectors can include gaskets, potting material, and other structures or materials to seal electrical connections in the connector from moisture ingress to prevent damage. The connectors can be locked to secure the one or more flexible circuit board in place in the connector. The connectors can be unlocked and then opened to remove the flexible circuit boards to remove components or to rework the electronic device.
