What is the repair procedure for a USB port that has ripped off the PCB and can't just be replaced ? I can pick up the tracks on the pcb and solder wires directly to the 5v + and gnd to a new port ?

I'm looking at it through a x40 lens and its still a fiddly job, what kind of micro soldering set up would i need for this super fine work ?

What type of USB connector is it?
Post a photo of the PCB and tracks so that we can see the damage.

 

A fine-tip temperature controlled iron is needed. I use a Thermaltronics at home. https://www.thermaltronics.com/tmt-9000s.php

A fine-tip temperature controlled iron

Out of curiosity, what temperature do you use for those curved tips? Obviously, the 670°F I use for the larger tips is way too high... I have to repeatedly use tip cleaner on them to keep them holding solder. That and I wish I could find some smaller diameter extremely thin solder. .031" looks huge under the scope and IS for those fine jobs. I normally use Kester 245 no clean. I also keep a couple small tubes of Kester 44 in .020" & .015" have to remember them next time I'm putting down SSOPs.

Bright light and magnification will help too.

It's a RF curie tip. Set temp per each insert.

I'm using the HakkoFX-888 iron but I suspect the big problem is using some off brand tips... Seems that the tip temp is not that far off from what your using.

This is the tip I'm using for most SMD boards.

UFTC-Ultrafine Solder Tip Cartridges are the standard soldering tip range for the Metcal MX-500, MX-5200 and MX-5200 series soldering systems. UFTC cartridges are available in temperature 700-series nominally 380 ˚C. The temperature/series is designated by the first digit following the dash in the part number. Metcal recommends the 700-series UFTC cartridges for small components or high density packed PCB’s. Can be used with leaded and lead-free solder. The Metcal "SmartHeat®-Technology" automatically adjusts power levels during each soldering operation.

Time to get a new tip but it still works great.

40W soldering iron is defacto standard for 1 oz copper PC board. Helps prevent lifting/separation of the trace from the PCB. Anything hotter can damage the trace. Be aware, you can only remove/replace a limited number of times before the trace will begin to separate.

 

"Tinned with Lead Free alloy;NOT OEM, But of High-quality" I think the NOT OEM says a lot more about them than the High Quality... They look good new and are copper plated and tinned (lead free) but I've retinned them and using with Kester 243. But as you can see the tip is burning off without much use @670°F and as I said I'm having to fairly often use retinning compound on them to get them to hold solder. I will use the Kester 44 smaller stuff next time as I am still putting some SSOP chips on DIP adapter boards for breadboarding.
Hard to see in the picture but the used one still has the copper plating but solder not sticking to it.

I also had some straight fine tips From Amazon that I sent back years ago because they simply burned up the first time I used them. Burnt a good 1/8" off on first use. Went from fine to blunt fast. Pure Junk! You get what you pay for...

Been there, done that and wired in the bodges to fix it when possible. Sometimes not...

The nice thing about the RF irons is the almost instant heat to correct temperature. The iron holder has a idle magnet that changes the curie point to lower heat automatically with physics instead of electronics. It's already back to stable working temp in the few seconds from the holder, to cleaner, to board. Clean the tip and tin before it goes back to the holder for irons that stay hot if it will be while before next use. High quality tips (tools in general) are a must, no-matter the type of iron. Repeatability is the key as you build muscle memory for automatic good joints, every time.

I never use a wet pad on fine tips.

 

I just did another SSOP and turned the iron down to 650F and used a fine straight tip with .015 Kester 44 and it went much better. Those curved tips I have are junk. I like the shape, but those tips are trash. I'll be looking for some better ones.
