I've assembled countless pcb boards but never a breadboard. how do components connect together?

prototype boards have through hole vias spaced 0.100 inches appart in a rectangular grid. the components are soldered. not the same as a breadboard.

are these boards lead free? do they use a lead free tinning process?

Sorry.PCB board is not lead free.Using lead-containing tin plating process.
