If you've ever attempted to desolder a busted USB port from your child's tablet, you'll know how hard it is. This stuff makes it easier by reducing the melting point of the old solder. It's better if you have a hot air rework station but it's quite doable with a standard soldering iron.

This is a great price for the kit and is currently cheaper than bulk buying the alloy on its own. The kit comes with a tube of gel flux and alcohol pads. Get that old tablet out from the cupboard and get repairing.

Lot's of tutorials on YouTube.

For the best option without special tools would be to use wicking braid!

Seems incredibly expensive if it will only work for 10 SMD! Looks bigger than that. Is the solder just old fashioned lead based solder? (no I can see it isn't now)

The best option for the minimal low level jobs. You will be there all day trying to use braid to repair for example an hdmi socket.

it seems expensive, the time saved easily covers that though. This is the main go to when replacing HDMI sockets on PS4 etc. with ROHS and thus lead free solder, higher temps are required to get melt the solder, particulary when attacking the ground pads as these are all connected within a layer of pcb and acts as a giant heatsink drawing the irons heat away.

If you do any sort of pcb repair work at home without access to reflow ovens etc, it pays for itself.
Haven't tried this, I use a Desoldering Vacuum Pump . I can't remember how many years use I've had out of it.

Lead based solder is better quality, for example use for medical or army device

Well I teach solder repair to NASA and ESA and some flux and braid is the best way to go in my opinion....any half decent soldering iron can reach 300+ degrees C to melt lead free solder which has a melting point of approx 210 degrees C.
Useful, braid usually works but if you're unlucky you rip off a track or two. This stuff is supposed to be quite good.

Us pros just use leaded solder to reflow then some flux, braid then lever the bugger off.
This is awesome stuff, originally used it to quickly remove and re-use 100 pin TQFP’s on the original Xbox to make them 64meg! Now I always have a bit to hand for quick fixes
Louis Rossmann does board level repair of Apple machines on youtube. He does not speak well of chip quik but if you don't have a rework station and it's for yourself then it may be worth a try. +1 for leaded solder!

To be fair you could probably suck up pads etc if not careful, but they're still what I'm used to.
You could always use a car halogen lamp for SMDs

Eutectic is even better

Agreed with extra old fashioned brown flux
All these "pros" giving advice and saying about how they use leaded solder, or "sodder" as our stateside cousins would say, and not one mentions that leaded solder is illegal in the UK. Thats why you'll only find the totally crap unleaded stuff these days.

You will find due to RoHS it wont be in new electronics, but you can still buy it: uk.rs-online.com/web…15/ and use it for repairs and projects.

I am not a "pro" at eletronics or the law but I am pretty sure it's not illegal if RS components are selling it.

Just follow the HSE while using leaded solder and you'll be just fine!

I don't think this statement is completely true. I believe that leaded solder is banned in manufacturing i.e. mass producing, but ok for everybody else e.g. repair shops and hobbyists are allowed to use it. It is readily available from suppliers. CPC sells leaded solder.

It's not illegal to buy or use. Mogsog has said it all really.

When I said 'us pros'..... and then mentioned 'levering the bugger off' was said in a not totally serious way, no pro would surely admit to levering off a component, even if we might actually do it. Anyway I could be pretending to be a Pro so best to never believe anything said online ever, we're all terrible bullploppers.

Anyhoo back to solder, the 'tin whiskers' that can occur with unleaded solder can and has caused major problems, sure it won't matter in a DVD player or computer, unless that computer is inside a satellite or plane!
For my own repairs and such like, I'll continue to destroy the planet by using a few grams of solder once in a blue moon. Driving my car to work and back will probably be 1000 times more polluting that a couple solder joint repairs each year.

Leaded solder is not illegal in the UK, I use it on a daily basis at work to rework qfp's and a any number of other things. Some of our customers actually specify lead solder infact. If it were illegal how could we still purchase leaded solder wife, leaded solder paste and leaded bar solder for our wave soldering machines?
Thanks for putting me right. If I'd known that I would've repaired a lot more stuff instead of scrapping it. I have shaking in my hands and find it nearly impossible to use the unleaded stuff. Now I'll go looking for some locally.

The leaded solder wire I use at work is great stuff, it has water soluble fluxe instead of that horrible rosin so all you need is a dry brush to clean up. If you find you take pads and tracks off easily I'd recommend using a heat gun, just the sort you buy at b and q. Make yourself some heat shealds from old tin to protect the surrounding areas or Kapton tape is good to. Then add some of the leaded solder before heating up the component, this adds new fluxe and lowers the melting point of the solder.

Thanks for the advice. Have you any idea which brand, if any, you use?

I've been wracking my brains trying to remember the brand while I was writing, I can picture the label but can't quite remember, I'll let you know tomorrow when I'm back at my desk
Cheers
I believe that military and medical equipment still uses leaded solder, I could look on Wikipedia to confirm but am confident someone far smarter and less lazy will be along to tell me

He's a really odd bugger and can't quite get to grips with him, clever, knowledgeable but a VERY typical New Yorker (if the Simpson's have taught me anything)

Agreed, he is not somebody I could meet but he's fine for passive background company while I do the dishes. ​
Alternatively, someone who deals with TV repairs should know about SMB soldering.

I was replacing an iPod Classic hard-drive and accidentally pulled off the battery connector from the motherboard. Turned out it was this type of solder. I was at a dead end until someone suggested a TV repair shop. I went in and he seemed baffled.

Anyway, he managed to fix it and only charged me £10.
