Nobody reads instructions anymore. The manufacturer advises to heat it to 250c on first use and to coat the tips with rosin core solder before using it. The smoke is due to a protective coating they apply before shipping.

Nice demo, well done. Mine arrived in UK with an Australian plug and no adapter in spite of saying UK plug in ad. Switched on and within five seconds there was a bang from within handle. Dismantling showed both filaments shattered. Full refund followed. Filament replacement not easy to find at present. Fact that it is claimed to be able to cope with 110 and 220 volt +/- 10% fills me with scepticism.

I've been using professional soldering tweezers in a previous job and usually you can just hold and use them like regular tweezers. Haven't tried electrolytic caps, but for most SMDs you can just pick them off. However even with those it's easier to just use a regular (professional) soldering iron for actual soldering.

thank you for the review, i will buy it. desoldering tweezers are quite expensive, and trying to remove smd caps is a pain and in most cases can ruin the pads on the pcb. Some people start twisting the cap with pliers but i found that to be risky

Twisting capacitors off may be OK for some professional PCBs which have super-thick copper, but will certain cause destruction of most consumer grade PCBs.

I don't think bangood would appreciate the less than stellar review. LOL. They might come after you for this slip up

I am thinking of getting Atten ST1509-N100 they are similar to the Weller ones in design but more on a budget price. They are still expensive around £200 so there certainly not cheap at all but compared to the Weller soldering tweezers that cost up to £1000 the Atten tweezers do have an attractive price I do hope they bring more soldering heads out for the Atten ST1509-N100 in different shapes as I can only find 3 heads and the tweezers they are coping with are the Weller ones. These types of tweezers have a different design that helps grab components and get into narrow places. I have the Yihua 938D with tweezers they are slightly different from the ones shown in your video but based on the same design they have a 70w soldering station I think each tweezer gets 45w. I don't like these tweezers terrible design and their hard-to-grab components. I find them a nuisance and when I get another money saved I am thinking of buying the Atten ones they seem great value for money and are the right shape for the job.

In some cases this the best way , is very important to have diferent options. Cheers.

mr video99 has this soldering iron been reliable throughout the years ...as it still functional ?working ordid it break?

@video99couk Жыл бұрын

Still works fine. It's best used with flux and a pre-heater if you have one. Like this: kzfaq.info/get/bejne/nZmgfdeHubKvYac.html

@stefanBEAR98 3 жыл бұрын

are you still using it?

@video99couk 3 жыл бұрын

Yes, with pre-heater and flux, it's helped me to change many capacitors in particular. Sometimes though, I will still use a pair of soldering irons instead.

@Dahna_ 4 жыл бұрын

So you don't use flux?

@video99couk 4 жыл бұрын

I was demonstrating just the soldering tweezers in this video. You will see on a later video that I use solder flux and now also a pre-heater.

I thought most people use hot air station for SMD.

@video99couk 5 жыл бұрын

That's not very practical for removing two-legged components such as capacitors. There's a high risk of blowing off other nearby components. I do use a hot air station too, but not for capacitors, they are better suited to multi-legged semiconductors.

I've just bought one and it's seriously bad. Mine doesn't even melt the solder ! To remove a cap, I need to add flux, add solder, set the temperature to 350°C, wait 2 minutes applying pressure like crazy and then force the SMD cap out like people do when they don't bother desoldering. I've removed 15 caps, one pad is broken, on is lifted, it took me ages and I can't feel my hand anymore because of the pressure I had to apply. Oh, and I had to bend the tips because they weren't the same length ! I paid £40 for this crap... This is really bad, I get way better results with a single iron... (oh btw, don't worry about my broken pads, I've done it on a dead board) Avoid if more than £10

@video99couk 4 жыл бұрын

Some adjustment (though not usually bending) of the tips does seem to be needed. Adding flux is a good idea anyway, I do that now. I find it does a good job where you can't use hot air because you would blow other devices off the board. Results of course may vary from one board to another.

@@video99couk I've been using it all afternoon, now I have a better feel for the tool and it's a little bit better (pretty good actually). I have to set the temperature way higher than I'd like to (380°C) to get good results. I've paid it around £37-40 too, in a sense, that's not expensive, but I've paid my soldering iron £40 as well (KSGER T12 with cartridge tips) and it's way better so in comparison, it feels expensive. Seeing your video, it took you way less time compared to me to do a decent job. I leave my previous comment just so people will see that they won't be the only one yelling at their tweezer for an hour before managing to get the job done =) Even though I feel that in a couple of days I'll do even better, I will still be on a lookout for a better one, it'll do the job in the meantime though. Have a great day mate

@@video99couk Good review, I just purchased one of these and it was dead out of the box. Not completely, the thermocouple wasn't working so it would not heat up for me. I opened up the Power Supply and found that one pin had come out of a housing and pushed it back in. Voila! It worked. Didn't want to deal with sending it back to China, so really glad I decided to open it up. BTW, there are hot air nozzles out there with 2 fine tips, 4 tips to make a square....all kinds of sizes and shapes actually. Yihua even makes a TON of hot air nozzle tips, As do other manufacturers. I need to order some to try with my hot air station. And @SLR Mod Shop, when desoldering(& soldering), you should always use a high quality flux(and be liberal with it) and a small amount of solder. It also helps a whole lot to use "desoldering solder", the technical name for it is eutectic solder material. Try ChipQuik or FastChip removal alloys. I've used ChipQuik and its great stuff.
