Development has happened!
MicroSd cards are backed up by removing the paint layer on the back of the card, and then soldering the “hair-thin” copper wire (s) on the visible points of attachment and using the copper wires to fit the reading unit. The real development lies in the fact that we do not need to bake now, which – in truth, in many cases is not easy – so we made different slots that we made our work faster and more accurate.
