Solder paste (or solder cream) is a material used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through hole pin in paste components by printing solder paste in/over the holes. The paste initially adheres components in place by being sticky, it is then heated (along with the rest of the board) melting the .

How does a circuit board get made? Maybe you have a rough idea of the steps involved: someone designs a schematic, which is made into a layout for the physical design, which then gets exported into the machine-readable files. Somewhere after this, those files are sent to a printed circuit board (PCB) manufacturer, or the “board house”, who manufactures the boards somehow and then ship them .
