My first experience with anything like surface-mount technology.

The microUSB charger input for my grand-son's BeeWi blue-tooth amplifier had come completely adrift. I found that only 3 PCB traces went anywhere - 2 at one side and 1 at the other. The little lugs at the sides of the microUSB socket had both snapped off so I needed to solder-suck those remains from the PCB.

I scraped the top of the socket and soldered a piece of tinned copper wire to the top, then bent the ends round underneath so they were able to go through the original lug PCB holes. Having soldered those in place I found that all I had to do for the microUSB pins was to heat (& therefore reflow) the relevant connections using my not-very-small Antex.

Happy to report this all works fine now and the lad is delighted.

This might be relevant for other microUSB devices such as phones, RaspberryPi etc.
