B3 is Ground so you can connect it to any ground point. One of the adjacent caps (C1552) will do just fine.

I have not had to run this jumper before, but this is where I would go if I had to. Or scratch to the ground plane (Or anything in Red) and use Solder Mask after running it :) Hope this helps...

UPDATE TO FOLLOW UP QUESTION

Congrats on the repair! :) Good Job...

I found a link on Amazon for the one I am currently using:

And the Pics below show the difference in the basic jumper wire to the wire I pulled out of a vibrator motor in a Iphone 5C (as well as the solder mask I use)

Working a jumper on a 01005 pad, directly next to the CPU seems a little overcomplicated :>)

por

True...didnt think about that. Just looked the closest and I was looking through my scope at a 6 board trying to decide and it looked easier with a micro pencil and Vibrator motor wire to me but didn't think about tools that may be available to him.

por

That's what happens when you get so good that you think..."01005, pffft easy!" Welcome to the big leagues :>).

Thanks a lot Guys.. I solved it.. I follow Michael suggestion. I m a beginner.. so the jumper doesn't look like perfect.. but the phone works perfectly.

Tomorrow i post the pic.. because i want to asked something about solder mask..

Michael cuold u plz tell me which micro pencil you use for soldering.. because i use the simple tips, but sometimes its very hard to work on phone boards, and tell me also plz the about vibrator motor wire..if possibile plz upload the pic..??? i use the finest jumper wire. Thanks a lot both of you :)

Lol @refectio ... Not quite there yet but have been having a lot of success at 99% of the jobs sent my way. I added the information to my original answer, You are most welcome

Thanks Michael.. I m practicing on the same board and i broken some pads (check the images plz) I make some jumpers.. and the phone is in half light condition :) I m not particularly interesting to repair the board, because i use it for learn reparing, I want to know is the jumper is right ( i mean to say jumper points :) The quality is so bad :):) i know ..

My second question is in this case how can i use the soldering mask, After reparing, if the board is function perfectly, i can put it on u1502 or only where the jumper wire running?? thanks

yes they are the correct points but you dont need to jump the 3 components you only need to jump to 1 component

I use the solder mask to cover my jumpers after running them to keep them still so they don't accidentally shift and cause shorts. Did you pull pad on C1597, C1552? just curious to what happened there...But you did a good job :)

por

Thanks both of u. So in this case i can jump c1597 with c1552 and c1552 with l1503 right??? (because the pad missing are 2 c1597 and also c1552.

Yes Michael.. unfortunally i pulled both pads. Probably the solder isn't melt and i pulled the capacitor :(

But Suppose if i pulled both pads... in a same capacitor....?? is there any solution in this case?

por

In theory, yes...but the capacitor is held to the board with solder, otherwise there's nothing holding the capacitor in place other than jumper wire...so maybe a good use of solder mask or proper glue. But have never had it happen

por

Thanks a lot guys.. your segguestions were vere helpful :)
