Great job.👏👏 Some free tips from my experience:❤❤ 1. When board is not crowd It's better to lower the temperature and rise the air speed and bigger nozzle 2. Use syringe and gage 16 or 18 needle for flux. It can help for less waste and easier cleaning 3.dont put pressure on aligning ic legs.first make its align and then solder those 2 first legs.with this pressure it can crack internally in the silicone 4. First use cotton swap and 99% isopropyl alcohol for cleaning, then toothbrush and isopropyl then put a paper towel and just press toothbrush multi times to soke that mixture of isopropyl and flux from board and also from toothbrush to make it clean.🙏❤️
@@ArminAkhlagh noted thank you immensely i will do try that technique i will alfo buy the cotton your teachings means alot you are highly appreciated sir
I have some soldering skills but I need to start practicing on PCB boards and SMDs since I want to get more proficient at it but have yet to sit down and start, something always came up! You definitely motivated me to get the ball rolling! Wish you the best with your journey, sir!
@@Turco949 thats you motivating me also all the best to you too i also work so i try by all means to practice whenever i come home early or before my shift especially when i work nights
@@Turco949 thank you immensely
Ncoo🎉
@@MgxotwaMandilive thanks
nice kid you have there
@@FreAk_dr. thank you sir
that problem is a basic check flex cable main board to lcd
Thanks though that was so Lcd issue i changed the lcd and it worked so i wanted to fix the one that us flickering
@@Chikafu.M @freAk_dr.
@@Chikafu.M it is not LCD issue its a flex cable from LCD to mainboard connection
@@FreAk_dr. oh ok i see otherwise the owner took it back i was gonna buy it though it had too man probably battery,keyboard and the screen
@@MurangaZW aw that's to many problems
wow
@@FreAk_dr. i am enjoying the easy ones
@@MurangaZW just start doing basics and that's good
@@FreAk_dr. thanks brother i love this and i wish i know more i even buy a thermal camera that i could afird from shein i thought it will be easy as i was struggling to finish the issue on a laptop i bought
@@MurangaZW issue..? what issue was it..?
@@FreAk_dr. not coming on tho the is a light when you insert the charger but on a first mosfet the is no power at the gate if i test if on diode mode it is shorted gat and source u removed the mosfet but still the same

In my opinion, it will be nice remind them to subscribe after they've seen the whole video and decided themselves if they like your content😊 great video by the way!
👍
@muhammedsemihtopcuoglu8438 thank you immensely
The PCB is not fixed, and sometimes it moves during the soldering process. Fixing it will help. Also, I recommend watching more videos and practice on dead boards and your experience will get better.
@@ziadfawzi thank you immensely i will do so i have lots of spare pcb and i am practicing every day
Good 👍
@@Qdacool_animations thank you immensely
Sure mawili
@@namhlajada740 thanks
Seems like you are eager to learn the hard way
@@FreAk_dr. not really there no school around here i would have gone for practical
@@MurangaZW ow I see.. to bad I hope I could share some of my lectures
@@FreAk_dr. please do will be highly appreciated i am struggling with testing diode i am beginning to think my multimeter is dead
air and temperature is very important
@@FreAk_dr. thats true if its too much you damaged the board permanently
@@MurangaZW some ic's are sensitive some are not
@@FreAk_dr. yeah that is why you need the knowledge by asking or play with the dead board
@@MurangaZW if you are my student I will require you to bring working unit, like tv, radio, laptop, cellphone, etc.. let's see how you could be good on doing circuits
@@FreAk_dr. if this gonna be an online lecture
Keep up
@@tashadzapasi thank you
like i said do not put to much flux in it...🤣🤣🤣
@@FreAk_dr. thank you brother we did it
!??
@@Qdacool_animations i got no idear i am seeking answers too
Haha, we've all been there! You got the job done. For this kind of size, using hotair to remove is a good choice. Another technique is the good old razor blade - cut the leads near the top of the ic, remove the plastic bit, and then use chisel tip with some flux to pick up the pins that are soldered on. This brings risk of breaking up pads though, if you are crazy with it. I think when soldering back on though, I would wick the existing tin off the pads, and then pin the four corners manually with a soldering iron, some flux, and a bit of solder on the tip of the iron. Then, after you pin the chip in place you can manually solder every pin using the drag technique or just doing it one pin at a time with a needle tip. Usually flux is a good thing, I think though you went a bit overboard with it. It just made you have to clean alot more. Experiment with your usage of flux, you may be surprised how little you need to get the job done.
@@andrewortman4402 amazing brother i take not i will try to do one by one hopefully you will see the video when i make one exactly how you explained i do not have better flux but i hopebi will buy soo as i am still learning Thank you immensely for sharing the knowledge
God... I take it back, leave those poor Boards alone!
😂😂😂😂 i Got plenty of them i aint done burning them 😂
@@MurangaZW x) subbed for you
@@abdoun8214 xxx come let i teach you to be the greatest technician to ever live😂😂
@@abdoun8214 also thanks for subscription you are highly appreciated
@@MurangaZW im an electrical engineer lol but yeah sure could learn somthing or two x)
Take time and practice you will get it
@@Chikafu.M thanks 🙏
That look so easy weldone
@@Chikafu.M thanks though
Get hot air to 340* and scalpel, heat up places where solder is "glue dot" - individually no need to try to preheat whole chip around whole time, put scalpel between pins where "glue dot" are from top to bottom and back out, you will get rid of the Solder glues from between the pins.
@@ArturSobkow noted thanks you and you are highly appreciated for sharing your knowledge i am greatful!🙏
You remind me of good old days
@@Arkkukie thanks are you now a professional?
My god ...
@@MoizRedYT it's funny 😁 isn't it 🤣
quit soldring bro.
@reedski it's too late bro ain't no way I will be quitting I have a lot of dead boards and I have a hot air station what should I do with it

Nice!
@@Qdacool_animations thanks
is bro not aware of solder paste
@@thatlittlefrog. no bro is learning though those are dead pcb that i use for practice
I somehow suffer from watching this
@@sherman5k756 how so?
Watch this ua-cam.com/video/P3F3CEKiypU/v-deo.htmlsi=3fPgJ_kyendNd_98
More flux and more solder is always the answer for this guy, but not s better technique
@@diegovianavillegas3297 thank i will take note what can i do to improve
well this is too relatable i think
@@AbdulHadi-uw4qy 😂😂😂 well when i see people doing it it looks so easy i guess its because of practice
@@MurangaZW true
@@AbdulHadi-uw4qy i did try again and i think i got it right even though it wasn't easy

good soldering but one tip, dont scrape the solder wick on the pads, just dab it on
@@WWFYMN ok thank you so much i am trying i have destroyed so many boards because of that thank you!
nice!
Thank you immensely
that is not soldering. that is put some solder paste and blow it with hair dryer. xD
What is soldering?
It is soldering and it went prefect!
@@zzzychui3899 thank you immensely!
@@zzzychui3899i agree with you
@@zzzychui3899no, there are solder paste residue that got onto the vias. That's an indication of poor technique.
@henryptung
Nicely done
Thank you! Cheers!
your board is having stressed it will bend is that a samsung board
@FreAk_dr. yes it is thanks Though the phone isn't working anymore I am learning because I am obsessed with soldering and fixing things
@@MurangaZW Good for you 😀 before anything else safety first before doing on circuit don't put to much flux
@FreAk_dr. thanks you so much for the advice. I will definitely put less next time
@@MurangaZW are you newbie of using hotair station..?
@@FreAk_dr. yes i its my girst time and i have only managed to fix one phone t ok change the scree it was huawei p smart 2019
Should take more care applying the solder paste. Here, it was covering components you didn't mean to touch, so you don't really know if you disrupted their solder joints or shorted anything. Think solder paste is also meant to be applied to the pads and heated with the component in place. What you did here is basically tin the pads, which is fine, but can also be done with less mess using normal solder and flux (basically what you did after). If you're using tinned pads, you should use an iron with an appropriately shaped tip to glide over the pins, heating each up and melting the solder underneath. Shorts between contacts can be cleaned up with some more flux and using the iron to remove excess solder. Accurate positioning and good magnification while working helps. Your initial chip position here seemed offset, putting pins between contacts instead of on them. Obviously, don't put the chip on backwards.
Thank you immensely noted i am definitely going to tryi what you said and i will send you the link
