How to remove PCB connectors
Printed circuit boards - widely referred to as PCBs - are an integral component for many industrial applications where space is at a premium, and are ideal solutions for high-powered and high-density specifications.
Widely used in consumer electronics, appliances, data and electrical cabinets as well as the automotive industry, PCBs provide a versatile solution that can house a wide range of connectors and wires, covering every type of device configuration imaginable.
Here, we explain the most common types of connectors used with PCBs and the method process required to disconnect them all safely.
To disconnect coaxial connectors from a printed circuit board, slide a thin, ESD-safe pry tool or tweezers underneath the wire until it feels snug against the connector, then pry it straight up from the board.
If you wish to reinstall, hold the connectors in place and press them straight down. The connectors snap into their sockets, similar to the metal snaps on a jacket.
Display cable connectors
Display cable connectors very often have a small metal clip that runs around the back of the socket to lock them in place. To separate the connector from the printed circuit board, push the tip of a spudger under the clip. Then, swing the clip over to the other side of the socket, so that it lies flat against the cable.
Holding the clip and cable together, pull in the direction of the cable to remove the connector from its socket. Do so gently to avoid any breakage.
Bundled cable connectors
Cables that are made up of multiple individually wrapped wires leading into a single connector are usually loosened by simply pulling on the cable itself. Pull the cable away from the connector in the same direction as the individual wires are running.
Remember to pull evenly on the full width of the cable so that no individual wires are taking unnecessary strain, which could cause them to break.
Power cable connectors
Power cable connectors have a small tab on the side that ensures they are locked in place. To separate the connector from its socket, squeeze the tab against the connector and pull it straight up from the socket. Some variants are extremely small and may break if you try to disconnect them by pulling the wires. You should try to pull on the body of the plug with tweezers, rocking it gently from side to side to ease out the release mechanism if necessary.
Sometimes, when disconnecting components from a PCB, you may encounter wires that were not intended to be removed at all and are soldered into place. Use a soldering iron to remove these wires easily from the solder joints.
Soldering each connection can be a tricky process, so be sure to carry out this method carefully in order to prevent damage to the printed circuit board and connections.
