This invention is a method of manufacturing printed circuit boards using a contact block packaging to provide and support electrical contact blocks relative to a printed circuit board panel. The contact block packaging is situated adjacent to the printed circuit board panel, so that electrical contact blocks of the contact block packaging are aligned with circuit boards of the printed circuit board panel, but breakaway stems supporting the electrical contact blocks are offset from webbing of the printed circuit board panel. The electrical contact blocks are then soldered to the printed circuit boards. Thereafter, the breakaway stems of the contact block packaging and the webs of the printed circuit board panel are broken, so that the electronic contact blocks are decoupled from the rest of the contact block packaging and the printed circuit boards are decoupled from the rest of the printed circuit board panel.
