So I have this router Xiaomi router 4c
And in many online forums I have seen that the router has usb capabilities which I confirmed from OPENWRT forum

But the problem is the d+ and D- point are so small I tried to solder but I had no experience with it and had old tools, so it wasn't working out

So I was looking for someone who have tools like
Pointy soldering iron or maybe microscope or something like that tools which are used for this purpose

The soldering point too small

I live near katraj, Pune 46
Maybe I can come to your workshop

if you have no experience in soldering, bhai don't do anything , i am also looking for learning these type of soldering , hope someone helps

there are Microscopes available that have clips to fix the board that is to be soldered and that is what most people use to solder these types of small points.
Also, my soldering is not the best when it comes to such points.

Well there's no need of microscope or like
But only require that pointy soldering iron

I tried with one that looks like angled chopped
But the problem was it was not heating at the end point it was old and cheap one without any temperature control

Any pointy one would do just need to heated

Does robu Pune have any services like this, workshop and like

Haa, Service to nahi at least Basic guide
"How to" ,
"Precaution",
"Tool required" ,and
"How to Use"

Video ya Forum post thru steps With image/Video with their parameter, ho to achha hoga

i hope someone upload guide and tutorial about soldering like these,

bhai services, workshop hogi to Local's ko hi benefit milega

It looks like the micro soldering on the vias, also known as "Filled Via."

Via hole that is completely closed using a conductive or non-conductive epoxy material or copper plating. The practice of filling vias is a PCB manufacturing technique that serves to enhance the reliability of the circuit board by reducing the probable occurrence of trapped air or liquid in the via, which can lead to failures during the assembly process or during application.

Microvias, buried vias, and plated through-holes are filled with conductive or non-conductive materials for the following benefits-
1. Tighter BGA pitches
2. EMI reduction
3. Increased heat dissipation and electrical conductivity
4. Reduced layer count or board size, which translates to overall cost reduction
5. Boosts routing density
6. Fast signal traces

Filled vias offer many benefits for PCBs; however, hand soldering increases the risk of damaging traces and layers on the PCB. I recommend avoiding hand soldering of vias. Instead, consider reaching out to a local assembly service for machine soldering, as it is safer and more reliable.

I hope this information is helpful to you *:)
