ABSTRACT:
Leadless chip carriers (LCCs) are pretinned using wave soldering equipment. A magnetic fixture having a coating of material which is non-solderable provides a plurality of LCC retention locations. The LCC retention locations are configured to ensure free solder-wave access to all edges of the chip carriers disposed thereon and to substantially prevent the dislodging of the chip carriers by the forces of the solder wave.
