Unsoldering/resoldering?

Postby Ttaskmaster » Wed Feb 12, 2014 12:21 pm

Hi guys,

As promised, here's the first of my Noob questions...

I placed an order for some pre-built LED pattern circuits, built on basic PCBs, so I could study them and learn how they achieve their results.
However, I had to email the seller with my colour requirements, but the email did not arrive until after the circuits had been dispatched.

My question is - How easy/advisable would it be to unsolder the 5mm LEDs and put my own on instead?


Thanks,
Tasky.

I suppose it depends on how many LEDs you're swapping, how close they are together etc.

If you use a solder sucker and can't get all the solder off you can usually wiggle the end of the pin with mini long nose pliers to break the last bit of solder off.

Okey doke... Well, I completed my second Velleman kit just now and this one actually works, so I may well give the unsoldering a go.

Do I need to check anything specific about the type of replacement LEDs, or will typical 5mm ones from Maplin suffice, do you think?

As Rich says, a desoldering pump is fairly handy. We have them in store here:

Wick is pretty handy too:

The pump takes off the bulk and the wick is for the little bit that's left. Desoldering is a skill in itself and good to practice.
