ROLL SOLDER COATING DEVICE

摘要

PURPOSE:To simultaneously coat both sides with solder while horizontally feeding a lead frame by forming a package passage groove larger than a package, and increasing a gap between a coating block and a coating roll. CONSTITUTION:A package is formed in a sufficiently large size at package passage grooves 43, 45 so as not to be brought into contact with melted solder 32. A lower surface of a lead frame 1 is coated with the solder 32 adhered to the surface of a coating roll 37 and raised. Excess melted solder 32 is fed upward from a hole formed at the gap between a lead and a lead, retained in a gap to a coating block 44 to coat the upper surface of the frame 1. Accordingly, the frame can be simultaneously coated on both side surfaces while horizontally moving the frame.
