Removing solder

Solder wick.

It's best not to solder stranded wire to a board. The wire tends to break if flexed.

Good to know.

A pump. But add solder for removing the existing solder.

for multi-pin parts these are good,

but for stranded wire, just melt the joint and pull.

always remove enough especially when the solder is in stranded wire.

Does adding solder make the existing solder bigger so it can be sucked up e asier by the solder pump?

Andy

thanks. Aliexpress is really cheap.

Thanks.

I discovered a way of removing some components.

The weight of the clip pulls the resistor down while the solder is being me lted.

Use solder wick. It will even draw solder out of holes, to remove ICs:

It increases the surface area of the tip that is in contact with the joint, allowing more heat to flow into the solder.

Also, if you press gently sideways on the component lead as the solder is melting, you can often feel it move when the solder has completely melted through.

That's when you apply suction and remove the iron.

That's true of any wire. Stranded wire with solder wicked in it is the same as solid as far as metal fatigue goes.
