I appreciate your soft and pleasant voice , it makes it easier to watch the detailed approach, talking as you do it with advice of what not to do, is good for those who want to learn well done mate. So many pit falls out there, so tried and tested ways are best to start with, as you say drag soldering is good if your skilled at it,I'm old and do many solder through components over the years. People ask me how i get the solder to look so good, I tell them it takes many years of trial and error you develop your own technique over tine. Being able to watch a pro do it with ease is a pleasure to watch and learn, so thanks for all you do to pass on your techniques, your a gold mine full of knowledge.

Excellent video, with some very professional soldiering skills. I'm 54 years old and have been soldiering components since I was 12 years old. And I still can't produce that level of soldiering skill. Very well done... I have always struggled with flat ribbon connectors. I going to try your way. I greatly agree with you about the flux... Every teacher or instructor has drilled that into my head... Flux, flux, flux... Thumbs up and a sub has been earned here. Thank you.

[@mrsolderfix3996]

Hi , thank you for supporting my channel , very much appreciated. I guess I've just done so much soldering over many years that now it seems easy really . I've spent many years doing microscopic work that's got smaller and smaller , a particular favourite these days for me is using one strand out of a piece of solder braid to do wire modifications . But that seems pretty easy as well now . Practice , practice and always listen to other people and be willing to change your methods if you learn a better one . Thanks again, and keep soldering 👍

My first attempt at soldering 1206 components was a disaster. But after studying several of your videos I can happily jump in and solder 0603, sot 23 etc. I certainly won't say I can come close to your quality but I no longer find myself shouting and screaming at the PCB when it all goes horribly wrong! Take a bow Sir. You are truly the master! 😊

Hi , you will be ok . I do all similar packages from 1206 down to 1005 using the same method . The more you practice you will get better and can go smaller and smaller with relative ease . The 3 main things are try and get some 0.25mm solder , use flux and use fine tweezers . Good luck and thanks for your support 👍

[@SeanChYT]

I am a very big fan of your videos. Great audio and video presentation as always, educational and very good narration as well. It seems you achieve great results with a sharp conical tip, something I will have another go at myself. I started out mostly soldering with larger bevel/hoof tips, as the KZbinrs I followed in the beginning seemed to prefer those. I myself have had difficulty melting the solder with these smaller conical sharp tips, but I just got a new soldering station with JBC genuine tips, so maybe that will help me. I try to keep the tip clean as much as I can, avoiding too high temperatures and excessive oxidation, dirty tips, adding fresh solder to achieve good heat transfer, flux, etc. The new station also goes to sleep immediately when I return the tip to the holder, and heats up again extremely fast. Any other tips for being successful with the conical tips? My hands probably will never be as accurate with the tweezers though.. Your skill is truly inspiring.

[@mrsolderfix3996]

Hi , thank you for watching the video's and commenting, much appreciated , I'm glad you enjoy them . I use a few different irons these days , for all my KZbin videos I use a Weller TCP S iron and PTP7 conical tip , very old school iron but I love it . Sometimes like everyone else I can struggle with the tips getting oxidised and not accepting solder but I gently scrape with a scalpel blade or light emery cloth and this seems to do the trick . Keep buffing up tinning , buffing , tinning etc until the solder starts to take normally , you always get there if patient. I also use modern day Metcal irons which are really nice ( very expensive ) and these don't seem to suffer to badly with this non tinning problem ( hardly ever ), but if I have the same problem I just buff with Emery cloth ( very lightly as these tips are quite sensitive to coating being changed ). As with all soldering issues you get to learn what you need to do , hopefully I can help a small part in some of these issues as well as the other good soldering channels on KZbin. Thanks again , good luck with everything 👍

[@RanLottem]

Thanks for the video and the clear explanation. One thing I think I'm still missing is in the first stages after you apply flux - do you tin the tip of the iron slightly and that's the tin that gets applied to the pad? Does it go from the iron to the pad because of the flux?

[@mrsolderfix3996]

Hi , thank you for your comment . I always add a tiny amount of solder to the iron tip before I do any soldering joints . I also pre flux the joint first then place the iron tip on the joint , then a split second later go in with the solder . Works every time. Hope that's clear . Thanks again for your time 👍

[@dazamad]

Another great video. Do you have a picture of your solder iron tip before filing it down? Ive never done that before and cant you purchase a finer tip one. Thanks

[@mrsolderfix3996]

Hi , thank you for your comment. The Weller iron I use ( TCP S ) allows the tips for this iron to be filed down . The one I purchase mainly , PTP7 is the finest one for it . It is fairly fine but sometimes for what I do I need it finer so just lightly shape the end to suit me which these tips allow . Done people say you can't do this but they are 100% wrong when it comes to these particular tips . There isn't a finer tip for this iron otherwise I would purchase that instead . I also use a micro Metcal iron where the tips are way finer so don't need to be touched. Hope that helps .

[@zukinokaemono]

Another great vid, thank you! By the way, what would you recommend to solder on a board first: some multiple pin ICs (like xilinx there), or components with fewer pins, like caps or resistors?

[@mrsolderfix3996]

Hi , thank you for your comment. When I'm building a board from scratch I would generally populate the smaller components first i.e 0402 resistors , caps etc and then the next size components up and so on. This can vary though . If I had a large fine pitch IC for example that was tightly surrounded by small capacitors I would do the IC first in this instance as it may be hard to get to it after the caps are fitted. You sort of just get a feel for what's the order when you get to look over the board your working on . Basically make sure you can get to all components if the parts near it are fitted. Hopefully that helps 👍

[@034G63EVO]

I have a question. When your doing the really small stuff, are you looking at the board or through a microscope of some sort? On things like resister packs and the like, I find myself looking at the scope, but it takes some time to get used to it.

[@mrsolderfix3996]

Hi , thank you for your question. I do use a microscope for the really fine small stuff ( you basically have to , even if your eyes are perfect ) , and i do get your point about the microscope . This doesn't affect me as I get on great with scopes ( I use a stereo long reach scope , allowing me to get any size board under it , purchased from GT Vision ( England ) , their own branded one . I know of people who just couldn't get on with scopes and used something called a Mantis ( spelt correctly? ) , but I really hated them . Scopes offer way better vision and the more you look through them you do get used to them . Hope that helps , thanks again 👍

[@reinthiemen558]

Doesn't the flux conduct electricity? How do you prevent the flux left below the components conducting electricity, creating short circuits?

[@mrsolderfix3996]

Hi , the flux I use is a non corrosive flux called SMFL200D which has very , very low resistance if left on the board , causing no issues whatsoever. It's the cheap fluxes from certain well known websites that may cause a resistance issue . Basically try and source no clean fluxes as these are safer in the long run .Hope that clears that up .

Hi . I've done a couple of QFN IC's in my other KZbin postings . Probably about 5mm square these ones . In my day job I've done many smaller than this . Normally I tin all pads with solder , equally on every pad including a suitable amount on the centre pad . Then simply heat gun the component on . Normally the device takes perfectly and floats perfectly into the finished central position . Also as I showed in one of my other videos I done one of the QFN's with solder paste. So 2 different methods , I just select the best method for each situation. Thanks for your comment 👍
