I have one mobile phone board. Probably it was buyd from our Gypsy`s "store" in our country.

The old microusb plug was almost gone. Maybe some pieces were left, but i removed them.

Have put rosin

on the pins of the plug and now only have to "catch" the plug to the board.

the solder i use is Solder Wire High Pure No-clean Active Soldering Bright 63% Tie Pen Thread 2%Flux

Thanks

 

So what's the problem then, set the temperature to 380C ???

 

63-37 melts at 183C
