How To Use Flux / When To Use Flux || Soldering Tutorial HD

[@GeekinTX]

I've been learning to do SMD soldering, and all the videos I've seen have a tool being used to apply the flux, and I couldn't figure out what the tool was. Finally, you've revealed the secret - it's a cable tie! 🤣

[@mrsolderfix3996]

Hi , thank you for watching the video and commenting , very much appreciated . The cable tie has been revealed, seriously it works really well . Thanks again , take care 👍

[@andrewg3122]

I use a small paint brush. Works well

[@bryanwagner1764]

​@@mrsolderfix3996 what do you use now, hasn't that specific flux has been discontinued?

[@IncaTrails]

When hand soldering, flux is your best friend! When desoldering using a braid, I apply flux via a flux pen to the braid before starting. It really improves the capillary action of the braid

[@mrsolderfix3996]

Hi , thank you for your comment, much appreciated. I agree , I go on about flux all the time in my videos , it is essential when hand soldering . In this video I mention adding it to the braid as this can really help at times , the only difference is I use a cable Ty to apply all of my flux and not a flux pen ( not a big fan of these ). Thanks again 👍

[@JustAnotherAlchemist]

Quicker/easier way to clear a through hole is to use a wooden toothpick; preferably bamboo. I can clear a dozen or so holes enough to get wires/pins in using just one toothpick. Simply liquefy the blockage, push the toothpick all the way through the hole, then remove the iron to let it cool, pull out the toothpick when the solder is solid. The wood is "solder phobic" so the solder won't stick to it. It is also heat resistant enough that it will survive long enough for the solder to solidify. Of course, use flux for a clean job, applying some to the toothpick really helps.

I'm just about to both do my first surface mount soldering and design my first pcb. i had discovered the 1 inch on each side braid trick on my own but sliding the braid and using flux made it go so much easier. thanks for the tips!

Extremely informative and useful video, thanks! Unfortunately, the SMFL200D ( nor its smaller pen version SMF12P) flux is no longer in production., accordingly to Farnell and other dealers. What alternative could you recommend, please?

I’m in the same situation, can’t find any to purchase. An equivalent product would be nice to know.

Quality content, clear & straight forward, satisfying content to watch, I'm always saving these videos to my playlist & is valuable information to a would be tech & electricians. Always fascinates me on how circuitry works, but you need time, patience & experience to do it. I have a high pile of scrap electronics to work with, but I go by, if you cannot do it properly, then don't do it at all, & don't start until you have all the necessary equipment & setup.

[@lawrencemanning]

The flux you recommend is awsome. Used it to successfully solder some massive QFP parts, which I struggled with before. I bought some a few months ago after watching one of your videos and its fantastic. I use a milk bottle top to hold it prior to applying it with a small brush, but I think I'll give it a go with a syringe. Not sure if it'll dry out, but it could be worth a go.

[@mrsolderfix3996]

Hi , thank you , I'm glad it worked for you , but I agree it is a great flux . I've just posted this same video again as I've now got better editing equipment which gives the videos much better clarity and sharpness . So if anyone's wondering why I'm reloading my old postings it's only to show them in better detail . I will keep posting new videos when I can , as I've still got lots to show and hopefully people will keep enjoying them. Thanks again for your comment and good luck with any soldering projects 👍

I managed to find the flux under ESMFL200. It’s sold there in EU but it’s still available.

[@mrsolderfix3996]

Hi , thank you for your comment, maybe if it is still about some lucky people may be able to find some . All I've found is a couple of companies who have it but you have to order at least 12 so not really viable. If anyone has any luck please post on here . Thanks again , take care 👍

[@matambale]

A thought: you might make a video that focuses on adapting soldering techniques when using lead-free solder after years (decades) of leaded solder. Not sure if that's enough to make a whole video from, but I'll bet it's a popular topic. And thanks for the flux video, mate

[@neilmcpherson9140]

Thank you so much so for the master classes in methods for soldering and de-soldering. I currently use LaCo paste which is OK but it can be a bit messy, and I could do with something that behaves a bit more like your choice. Unfortunately both the SMFL and the RS Pro alternative have have been permanently discontinued (According to RS) so I am hoping you will return to this subject at some point.

[@neilmcpherson9140]

...Sorry , the word flux was notably missing from the note above!

[@mrsolderfix3996]

Hi , thank you for your comment. You are right the SMFL200D and RS alternative are no longer available which is annoying as I loved the SMFL and had been using it for many years. I am still looking for a decent alternative and have a couple to try out at the moment . When I find one I like I will post about it on KZbin. Thanks again , take care 👍

[@primeral]

I bought a kit online and it was missing the flux ... basically, there were zero flux given. Thank you for the informative vid, Mr SolderFix.

[@michaels1679]

I actually try to spread the fibers of the braid just a bit. Push backwards against the braid, add some flux, and see how much better it works. This increases the capillary action.

[@mrsolderfix3996]

Hi , thank you for watching the video and commenting , very much appreciated 👍

[@Scarlet_1971_cuda]

Thank you. I really like your technique. Do you have an update on what flux you use? I've checked and everyplace I've found a listing for Electrolube SMFL200D is marked discontinued. It's possible someplace has leftover stock, but not that I have found.

I suspect I'm not the only viewer who would buy a product you referred :D Thanks again for such wonderful content.

Question ... I am in the USA ... I am looking at Digi-Key. I don't see this type of flux. Can you recommend on I can get here (I don't see the one you recommended available on this side of the pond). Also ... absolutely awesome videos !!!!!!!! I have never touched anything surface mounted. I am trying to repair the instrument cluster on a 2009 car. I hand enough knowledge figure out it was the cluster itself .... now I need to repair it. I think it is the power supply on the board (works for about 10 min then goes blank .. unplug it ... let it set for a while ... plug it in, it works again). I was going to throw it away but then I started watching your videos ... think I will take a shot at repairing it. Thanks again!

Dear Mr SolderFix, I couldn't find the Electrolube SMFL200D flux you recommended anywhere, the only trace of this product I found at Farnell but it says "Out of Production". Gtek dry wipes aren't so easy to find either, I'm not sure if Grove Sales ships outside the UK. Alternatively, do you have other products to recommend? As a test I bought a flux called Topnik-LP1 produced in Poland, I haven't had the chance to try it yet, I know for sure that it smells terrible 😂

How did you clean the flux off after wicking? I was going to buy MG Chemicals 835 lquid flux, but one review said it dries solid on the part, so then I was going to look into no-clean ones but I have no idea what is best. And then I saw you just wiped it up with a paper towel?

[@mrsolderfix3996]

Hi , thank you for your comment. To clean flux off after soldering I always use a fluid called ultrasolve which is available from companies like Farnell , RS Components, Rapid Online etc and I use a soft dry wipe called Gtek dry wipes from a company called Grove Sales ( England ) , I would never use a hard paper towel as board damage could occur but the dry wipes dipped in ultrasolve are so soft and really used right will look after your delicate components.

Hi , your right looks like this has suddenly been discontinued.

[@SurvivalSquirrel]

I tried to do this with 0.5mm holes today. Its much harder. Any tricks for this?

[@Elfnetdesigns]

Step 1 - Only buy quality flux, solders, solder wick, and tools for the job.. Step 2 - See step one When you are in the business of bar level repairs it is not worth it to cheap out on this stuff. If you are a hobbyist you can go cheap but eventually you will stop that due to poor performance and possible pcb damage.

[@Haircut211]

I am somewhat new to soldering on boards and this video caught my attention. I really appreciate the info you put out and how the video is laid out. I went to find the braid you used, I live in the US and Amazon was the first hit I got on it. Is it normally $80-100? I don’t want to order it and find out it’s normally cheaper

Hi , thank you for your comment, much appreciated. That price is way to much , maybe it's a reel with a large amount on it , possibly 30 metres. A normal reel for the hobbyist would be roughly $10 . Try Mouser or DIGIKEY ( American firms ) , or plenty of other places online for a decent price . The best width solder wick to buy I find is 1.5mm . Hope that helps , good luck 👍

I loved your tips. As an older guy with vision that is getting worse. What type of microscope do you recommend? I love what ever you were using in your video.

[@michaels1679]

Look for a USB microscope. They are getting pretty inexpensive now

Hello Mr Solderfix. Great video. Will Weller's LW25 work for fine electronics and PCB's, as it has Zinc Chloride in it (read that it is acidic)?

[@mrsolderfix3996]

Hi , thank you for your comment . To be honest I've never used this flux but I see it's meant really for plumbing jobs . So I personally wouldn't use it but I guess you could take a chance if desperate . Sorry I couldn't give you a clear answer . Thanks again , take care 👍

[@d614gakadoug9]

*_NEVER_* use a flux containing zinc chloride for electronics work. It sets up an endless corrosion cycle. The chloride (chlorine) content reacts with copper to make copper chloride. That reacts with carbon dioxide in air to make copper carbonate, freeing the chlorine to react with more copper, and on and on it goes. "Traditional" fluxes used in electronics are based on natural rosin. Pure rosin isn't a very good flux but can work on metals that are easy to solder and bright and free of oxide. Most electronics fluxes contain "activators" to make them more effective. The most preferred rosin type these days is RMA for Rosin, Mildly Activated. It is adequate for most work. RA (Rosin, Activated) is more aggressive but it isn't always safe to leave residues because there is some risk of corrosion. The flux in the spray can in the video is an RMA type dissolved in isopropyl alcohol. There are lots of modern electronics fluxes that are made using a base other than rosin. Some of the "no-clean" fluxes are extremely difficult to remove. Of course as the name implies, they don't need to be removed for general work, but residues can cause problems in some cases and removal is necessary.

Hi , Isopropyl is a poor cleaning fluid compared to some others on the market It's cheap for a reason . The best one I've ever found is called ULTRASOLVE . It's on a different level to the Isopropyl and will break down and remove stubborn flux with ease .

[@ES-iv6wb]

I’ve tried to source the flux you recommend in this video. But I can’t for my life find any. I’ve tried all the USA websites.

[@mrsolderfix3996]

Hi , thank you for your comment. The flux I've used for many years SMFL200D unfortunately has recently been discontinued so I'm looking for a new type at this present time. When I find one I am happy with I will post it on KZbin. Thanks again , take care 👍

Hello Mr SolderFix, Did you find an alternative for Electrolube SMFL200D flux please ? Thanks 🙂

[@NicksStuff]

Good question, SMFL200D seems unavailable

[@mrsolderfix3996]

Hi , unfortunately you are correct, it is now longer manufactured . Luckily I still have a small supply to keep me going for a while . I have found another great liquid flux which is just as good made by Loctite . The only problem is it's only available in 1 litre or 5 litre bottles , not much use for the hobbyist that's why I've not really mentioned it . I will try and look up next week the code for it and add it to this chat in case anyone wanted an extremely large amount of it . Thanks again 👍

[@tonytafe]

Hi @@mrsolderfix3996 , you are an invaluable resource in regards to soldering skills and techniques. Did you get a chance to look up the code for the Loctite flux you are using?

[@astrolemonade349]

​@@mrsolderfix3996have you managed to find the code or maybe an alternative that comes in smaller quantities? Great videos!

Apparently SMFL200D is no longer manufactured! :( Any other good recommendations?

[@mrsolderfix3996]

Hi , you are right they have discontinued the SMFL200D flux recently which is a shame as I've been using it for at least 10 to 15 years and found it amazing. Apparently RS Components do a similar aerosol one so I might try that out but unfortunately it's about £10 a can dearer than the SMFL one . Thanks for commenting , take care 👍
