The micro USB connector was designed to use only 40-50% of the PCB space of a mini USB connector.

This makes it hard to hand solder without the correct tools and are best installed with automation.

A preheater makes the connectors much easier to solder because the preheater provides most of the thermal energy to solder the connector.

The hand tool provides the tiny bit of remaining energy to melt the solder.

Solder paste melts much easier than solid solder.

An IR wand is great because it does not create an air draft to inadvertently move the components around.

Hello everybody.

I am trying to repair a not-so-well-known tablet, Allview Viva H10 HD.

I need to replace the micro usb connector.

Problem is I don't know model name for it.

I've been searching the internet "by eye" and found nothing useful since now.

Your picture of the usb connector matches with the one I need.

Please, tell me where to buy it (link) and what is the name of it.

Thank you very much.

Make sure you pretin the connectors and the board pad.

when you add a little flux, you will get both ends of the solder to flow together more easily.

By hand it takes me too long to solder a single microUSB to want to do many of them. That is with a soldering iron; presumably much, much easier with reflow but I've not tried that with such connectors. Part of the time is testing the thing too. 200 would be a nightmare to hand-solder with an iron. I still didn't trust my work, and used epoxy on the two sides.

MiniUSB or the larger USB-B would be a far better choice if you need to solder many by hand with just a soldering iron.

Hi!

Hot air gun, solder paste and good cleaning before soldering.
