Solder or Bullet connectors, Advice?

[freemundo]

Why do I keep buying crap from ebay! It's more stress that the money saved.

I have recently got a Novak GTB esc and Novak 13.5 turn brushless motor.

The problem is the ABC motor wires are to short and need to be extended.

I have tried to unsolder the wires from the PCB and replace but the soolder seems to have higher melting point than my 60 watt iron can produce.

My only other options are.

Slodering the wires together or use bullet connecters?

Any advice?

An agnostic amen to that! Hence I don't bother buying anything for serious use from there. Rarely buy anything second-hand in fact because it normally needs money spent on it. Of course, all the stuff I sell is mint!

Solder a new, longer length on. Less loss than connectors.

So soldering is the way to go!

So twist the wires together, solder and cover with heat shrink.

thanks for the advice

you must be doing something wrong if you can re solder wires on ysing a 60watt iron, we manage it track side with a 30wat iron,what region do you race in ??

[freemundo]

I am trying to unsolder the wires from the Novak GTB PCB. I am based in the south east London, I getting ready to race ay Eden Park.

[bigred5765]

ahh sorry to far for us to help you,its a easy job make sure the soldering iron is wet with fresh solder before you try to unsolder it, or see someone track side thats do it before

[freemundo]

Stupid question, why does the wet solder help melt the exitings solder? Surely it would only melt when it hits a set temperature?

[ashleyb4]

New solder will melt easier and help heat transfer to the old solder.

Improved heat transfer....the solder on the tip flows onto the cold solder which in turn helps increase the area of contact to the cold solder on the PCB, makes it much easier!

[Edit] don't you just hate it when that happens!!! :-)

[leeleefocus]

Your iron will transfer the heat properley if you tin the tip a second or so before you use it. When people say wet they mean the solder is liquid.

Clean the tip before every new joint. Wipe on a damp sponge or damp cloth and then re-tin the tip just as you are about to use it.

You are having trouble desoldering the wires on the pcb because they are made to dissapate heat and all that is happening is as you touch the iron on the joint all the heat is being drawn away. You will need a proffesional iron to do this.

The iron i use is about 200 quids worth with variable temp. Even on max it can take a few seconds for the solder to flow on a esc.

Like you said if you cannot desolder the esc then just extend the wires by joining and then cover with heatshrink.

if it's a small tipped iron it won't transfer the heat well. I'm using a 50w iron with a tip bigger than a good sized pen and it does batteries and motors in a second or 2.

defiantly 'wet' the tip to aid melting. you'll be amazed the difference that makes.

[bigred5765]

30 watt wellar soldering iron 10mm tip £19 quid does the job just fine if you use it right

[ashleyb4]

Most good irons will do it ive got a 18 pound wellar 80watt large tip awsome.

[freemundo]

I have a good iron with a wide tip.

One question, when joining wires together should I tin the wires, then platt and then solder or platt them together and then solder?

Thx

[Big G]

what is platt?

If I join wires I tin both sides. then pop on the headshrink. then just warm the 2 up so they both melt and join.
