    Abstract: A lead frame assembly of indefinite length having a pair of spaced parallel carrier strips, collapsible rungs extending between the strips at regular intervals along the length of the assembly and a number of leads extending inwardly from the opposed edges of the strip between the rungs. The rungs are collapsed inwardly to seat the ends of the leads against the sides of circuit modules previously positioned between the ends of the leads. The lead ends are seated in recesses in the circuit modules and are subsequently soldered to metalized surfaces on the modules. Following the bending of the leads, the carrier strips and rungs are cut away.

    Abstract: A printed circuit board (100), PCB, comprises a top surface (101), a bottom surface (107), a series of M castellated orifices (102) on at least one of the edges of the PCB, and a series of N conductive pads (103) on the top surface (101) connecting to the M orifices (102) at respective connection edges (104), wherein M and N are integers greater than 1. Each of the pads (103) on the top surface (101) is partially covered by a respective spacer (105) such that an area between the connection edge (104) and a border (106) of a remaining pad area (103′) is completely covered by the spacer (105), and the connection edge (104) and the border (106) of the remaining pad area (103′) have a minimum distance of D, wherein D is a positive number. A solder leaking is prevented between the pads (103) on the top surface (101) and the castellated orifices (102) by the spacers (105).
