How do you remove circuit board connectors?
To separate the connector, gently push the tip of a spudger under the clip. Then, swing the clip over to the other side of the socket, so that it lays flat against the cable. Holding the clip and cable together, gently pull in the direction of the cable to remove the connector from its socket.
What is FFC FPC connector?
Flexible Flat Cable (FFC) connectors are ribbon like connectors, made of flexible plastic, polymers, films, or engineered rubber and have a metallic connector at the end, which is embedded in parallel to the base. The 2.54mm pitch FFC/FPC connectors are available in ZIP, Non ZIF, LIF and High speed versions. …
How do you unplug a Molex connector?
To unplug them, just rock the connector laterally side to side – gently, and only a little – while applying a lot of pulling force. Get your fingers right into the corner of those flanges on either side – that’s what they’re there for.
Can you reuse push in wire connectors?
Connector is reusable on solid wires of the same wire gage or larger. If reusing connector, cut and re-strip conductors. In order to remove a wire, pull and twist the wire back and forth. DO NOT RE-USE connector on stranded wire.
What are the different types of electrical connectors?
Electrical connectors are classified into three types based on their termination ends: board-to-board connectors, cable/wire-to-cable/wire connectors, and cable/wire-to-board connectors.
How do you solder a circuit to a circuit board?
To start, let’s solder a large component held to a circuit board with thru-hole solder pads. A capacitor was already removed from the two solder pads. Each pad was heated while the capacitor was pulled away from the board. Notice how the solder holes are completely covered with solder.
What’s the best way to clean a circuit board?
The eraser method is also particularly useful for cleaning circuit boards with copper components. Mix together baking soda and water and apply to corroded areas. Mix together baking soda and a little bit of water in a small bowl until you’ve formed a runny paste.
How do you remove power cable from socket?
Alternating from one side to the other, gently “walk” the connector out of its socket. Power cable connectors like this one have a small tab on the side that locks them in place. To separate the connector from its socket, squeeze the tab against the connector, and pull the connector straight up from the socket.
How do you separate the LCD from the circuit board?
Screws or twisted metal tabs commonly secure a metal frame, which compresses the elastomeric strip between the LCD and the circuit board. Release these to separate the LCD and the elastomeric strip. In the photo, bright light reveals the conductive traces on the glass of the LCD.
Can you remove a component from a circuit board?
The solder just won’t melt, making it really difficult to remove a component. Add a bit of solder, and you’ll see for yourself how much of a difference it makes!
How do you fill holes in circuit board?
Check the table height and solder wave height to be sure they are properly set for the circuit board. Apply liquid flux to both the top and bottom side of all the solder filled holes and to the leads of the connector. Place the circuit board over the nozzle. Check the position using the alignment light and activate the solder fountain.

What’s the best way to desolder a circuit board?
1. Turn on the heat gun. 2. Use pliers to hold the circuit board above the air streaTim. 3. Use a pair of needle nose pliers to pull the component out of the board. Tip: You only need to heat gun the board for a few seconds, or else you will melt the copper plating on the PCB and damage the board, as shown in the picture.
