First
Always mate 😁
5:20 why does he wire to the resistor instead of the solder point to the left of it? isn't creating a second path between that point and the resistor changing the circuit? I thought there was already a trace on the board between the resistor and that point
@@Walczyk it is not going to make that much of a difference to matter and I believe he chose to solder to the resistor as an example of how you can do it.
@@Walczyk hey, as @Engineering Scale Models Sao yeah, it doesn't made much of a difference and it would be better to solder to the via instead of the resistor in that case, but I just did that as an example of different ways of doing the job. As long as there's a connection to both the pin and the via though the circuit is complete and won't make a difference in terms of functionality. Great very valid question though 😃
Absolutely fantastic tutorial Phil, a learning technician shouldn't go far wrong learning from your video's mate awesome just awesome 👏🏻👍🏻
Cheers mate, hopefully they're helping people just starting out or even some experienced techs too, no one knows everything so it's always good to learn new things 😁
Top class video by a top class technician. Great video Phil awesome work and video presentation 10 out of 10 mate.
Thanks mate much appreciated 😁
My favorite series on RUclips right now, i love RUclips
Haha thanks mate I have a lot more planned 😁
@@TheCod3r we are looking forward to it
Thanks for uploading. As a novice and doing board repair as a hobby (and fighting like buggery to solder on a wire last night) your videos are valuable
Thank you mate, I'm glad I can help. Hopefully you find some of my future tutorials (what I have either in the works or planned) useful too :)
Nice work as always
Cheers mate 😁
IMPRESSIVE!!! That's awesome.
Awesome demonstration.
Thank you.
Great video's, keep on going...
Cheers bud 😁
Awesome tutorial. Thank you.
Cheers mate, glad you enjoyed it:)
Really good tutorial again Phil, thanks
Thanks mate glad you enjoyed it:)
Thanks m8!!! You make it look easy
Thanks mate, it will be with a little practice and eventually it comes second nature. I used to struggle my ass off doing this kind of thing lol
great tutorial (y)
Cheers mate 😁
Great video and tutorial
Cheers bud 😃
Just found your channel and all I can say is wow! Amazing repairs sir. :)
Thanks bud I appreciate that :)
you are the best really since you didnot have a high end equipment and your work perfect
Thanks mate, to be honest most of this work is about using what you have and practicing until you get it right. None of us are perfect of course and we all make mistakes 😃
Happy to see you break 11k subs mate. Thanks a lot for your guides
Thanks mate I appreciate it, and it's my pleasure I'm happy to help people 😀
Hi there, I was wondering what is the wire that you took from the microwave, I found one in garbage and currently have my friend Xbox one x and a new tp158 chip and 2 missing pads, your doing a great job sir, waiting for your reply.
Thank you
I noticed on the that some pads dont have an trace how would you repair that ?
Hi bro, any suggestion on how to choose a jumper wire? when to use a 0.1mm and when to use a 0.01mm copper wire?
Man i really liked this repair! it was seriously cool and it came out at the perfect time because i watched steve from tronicsfix do this same technique on a ps4 because some guy tore out a power supply connector and he broke all of the traces so Steve had to do this to fix it and then I watched this more in depth video of it, i’m so glad i found both your guys’ channels this stuff is so damn cool and interesting to me! love it!
Thanks bud I'm glad you enjoyed it, and welcome to the channel 😁
@@TheCod3r i’m really glad to be here!
great video, have just subscribed to your channel
Thank you bud, I appreciate the support 😁
Your technique is good dude! I just would use a different tip, something like a knife which can be pointier and draggy at the same time, but the jumpers look excellent.
Thanks bud. I don't get along well with knife tips for some reason. Just doesn't feel natural to me. I use my bevel tips for pretty much everything lol
Nice 1
Cheers mate :)
Where do you get jump wire 0.17mm
What tip temp do you use for this work?
which uv glue is that? and which uv lamp? Thx
I've come to like boards with lead free solder. In a situation like this you can use hot air on the chip you're replacing with lead solder without much worry about desoldering the components held in with lead free solder.
That's very true, lead free is just a lot more difficult to work with because pf the higher melting temps
Hi TheCod3r , nice tutorial! One question: Can putting a new soldered trace cause any lag/clock skew if not 100% aligned on the old trace, or does the increased width of the new trace compensate for that perhaps? Not meaning to question your work at all, just wondering how important the placement of the new trace is. Thank you, and keep making good content! =)
Hey mate, as a general rule it shouldn't make any difference to timings, or at least not a noticeable difference at least. For something like a BGA trace repair on RAM or an APU it may make a difference but I've never personally noticed anything at all like that. I could be wrong but generally i just keep jumpers as short as I can because increased length could technically cause increases in voltage drops
@@TheCod3r Alright, thank you! Also, have you tried any other solder masks than the UV curable one? The UV one seem a little difficult to apply. I like using electrical tape whenever possible myself.
Sir... I'm really enjoying your videos, and I have seen many other RUclipsrs. You are very thorough, calm, articulate and always to the point. Thank you very much!
Question please... when pushing down on the chip and applying hot air to finalize soldering, just before you touch up on the pins... I'd be worried that the middle ground pad might have too much solder on it, and some would come out and bridge with one or several of the pins... yet it does not seem to happen to anyone. Should I be worried that it might happen to me as a beginner? Could it ever happen? What can I do to void it if it can happen?
Thanks again!
Hello, do you livestream on Twitch? If so, could you link your channel? Great video!
I need a proper microscope like yours!
How did you get started? School or practice?
What kind of jumping wire
I just got a sun tan from the UV rays from this video. Its just as bad on Northridgefix channel, he is notorious for giving us a suprise tan and trying to blind us.
fantastic vid cod ? ill be subscribing next week the £1.99 thanks matthewbain
Thank you mate, I appreciate the support. Don't feel like you have to though mate, the content will always be free 😃
@@TheCod3r no i want too ? i get alot enjoyment out watching yu and £1.99 well worth it ! and get vids early
@@matthewbain2408 awesome 😁 I haven't released an early video for a couple of weeks because of pushing new content every couple days but next week I'll be uploading early for members again 😁
I don't get why you wouldn't put the chip down first then run the jumper's seems like your making this a lot harder than it need's to be
It's less likely to cause a bridge under the chip that way.
@@daevildriller How would it cause a bridge "under" the chip
@@alexkay1874 by running the jumper first the wire will make a good contact with the pad on the chip. Sk8rat has a point, it's very hard especially for a beginner to run a jumper with the chip in situ because it ends up bridging with the pads next to it
@@TheCod3r Ok but with the thick piece of wire under the leg of the chip this will force the nearby legs to not sit flush on the flat solder pads requiring you to force down on the chip or raise the leg out of position . I f you put the chip down first every thing is flat and flush . I get you want it to be like the circuit board but it's not and if it's not in the exact right place Problems .

Haha I'm sure you won't be, the trolls aren't here yet 🤣
Second 😂
