Abstract
854,574. Printed circuit assemblies. LIEBSCHER, A. Nov. 24, 1958, No..37764/58. Class 37 A printed circuit board having printed conductors on one face, is characterized in that the conductors are solder adherent and have integral terminal portions offset laterally substantially towards to same edge of the board to provide solder trapping portions. A printed circuit panel as shown in Fig. 1 has conductors 11 with enlarged off-set terminal portions 15. Holes 14 drilled through the board and the terminals take the leads 12 of components 13 (Fig. 2), mounted on the opposite face of the board. Connections between the component leads and the printed conductors are made by immersing the side of the board, on which the printed conductors are mounted, in a bath of molten solder and then raising one edge (e.g. the one shown at the top in Fig. 1) so that the solder flows along the conductors 11 to the terminals 15. A droplet of solder 16 is thus formed to bond the lead to the terminal.
