Soldering iron head.

[nightbreed]

I got the Goot TQ-95. I wonder where has got a large range of solder heads. I need a broader tip. The stock sharp point is real pain to solder with.

Some shops in Sim Lim Tower?

If Sim Lim Tower don't have it, you can try www.farnell.com they should have it but it is quite expensive.

i think both tips are about the same.. tried both before.. more of the skill actually.. but i suspect ur tip might be covered wif those black thing.. so have a habit to leave a ball of solder to cover the tip when ur letting it cool before keeping.. i ruined 2 tips before realising how to take care of it
anyway sim lim tower should have.. just bring down ur iron to test for fit, just in case.. it doesnt fit u'll have to make another trip down

Or you can use flux to coat and clean your solder iron tip with solder.
When you want to solder to connectors, put a little flux on the soldering areas and it will make your life easier..

Of another method is to file the tip flat, this is to increase the solder tip area and do the coating. I dun recommend it cos you might spoil your tip.. Try at own risk!! unless you are going to throw the tip away den you can try this.

If you want to buy, the tip you can try SLT. 4 floor ask ard.

Some things to consider when getting a soldering iron is:
Size of head must be proportional to size of iron wattage, too big head on too small wattage will mean it'll take forevery for the head to be heated up to working temp and one application of solder/use will deplete most of the heat in the head, making the next usage another eternity.

Too hot irons cannot be used on PCB UNLESS u have extremely fast working hands and good eyesight, u will risk melting the board or neighboring components.

Too low wattage irons are not recommended for battery soldering as u will have to leave the tip on the battery for too long to melt the solder. the long stay on the battery will heat up the entire battery internals too much risking damage.

There are a lot of references to see to when choosing iron for jobs. i'm not realy familiar but i think u can find most of them online.

personally, i use a 100W iron for soldering sub-c size batteries, sometimes down to kan 950 size batteries but have to be extremely careful. anything smaller will have the 40W working on them. still i get burnt boards and burnt cells occasionally.

Hmm. Ok, guys! Thanks a bunch!
