How to Remove Through-Hole Components | Soldering

Sometimes we need to change or remove a component or device on a printed circuit board for many reasons.

For example, if we have a device that's no longer working or we need to change the value of a component. Perhaps to change the frequency of oscillation or some other reason.

So we need to take the component off the board and replace it with something else.

If we want to remove a through-hole device, we need to first remove the solder from the hole and remove each lead from the device to leave a clean hole that we can then place another device inside.

In order to do so, we'll be using the solder sucker.

We're going to remove this resistor. In order to do so, we need to have access to both sides of the board. We change our vice position so we have access to the back side.

I'll hold the solder sucker and we'll heat on the top side of the board.

So we've removed the solder. Now we want to pull that terminal out of the board.

We heat the device again. Since some residual solder may remain inside the hole, pull with tweezers or pliers.

We repeat the procedure with the solder sucker on the other terminal.

Remove the solder. Heat on the back side of the board. And pull from the top.

Now our device is free.

You can see that both of the holes are clear.

That's how to remove a through-hole device from a circuit board.

He picked the world's easiest thing to remove. Damn.

Thank you so much! I messed up when applying solder to a RPI Zero and then realized It won't work at all... so I need to buy that solder pump now

Hey want if we don't have a Solder Sucker device to remove the solder from a board. Can we still remove the component with that tool?

what about a 6 pin thru hole switch removal? then an install of a new switch? I only have a basic solder gun here

I cannot access both sides, because it's a big capacitor (that has blown) and is soldered flush to the board. Additionally, the manufacturer has put what looks like some kind of resin all around the bottom of the components, presumably to force people to buy another product when the capacitors blow after a few years. What do you do in this situation? Melt the solder and pull v.hard with pliers? I heard some people suggest boiling the whole circuit board in water.... sounds risky...!

Sure, easy. But how would you remove, say, a 8 pin header? It's soldered at 8 points and you cannot do one at a time.

that was how to remove (1 type of) thru-hole device from a printed circuit board.... to be safe.... thanks...

Well, i need to remove 24 pin female header.... rip
