  • Apparatus and method for depositing solder material onto a circuit board
    Patent number: 6273327
    Abstract: A stencil (34) facilitates application of solder material (48) to a circuit board (10) carrying a through-hole component (14, 16, 18, 20, 22) and to which a surface mount component is to be mounted. The stencil (34) has a first surface (38) and a second surface (40). The second surface (40) is engageable to a surface (28) of the circuit board (10) having a plurality of electrically conductive pads (30, 32). At least one first aperture (42) is formed between the first and second surfaces (38, 40)of the stencil (34). The stencil (34) has a first thickness (T1) adjacent the first aperture (42) for depositing a first amount of solder material (48) within the first aperture (42) and around a component lead (24) extending from the through-hole component (14, 16, 18, 20, 22) into the first aperture (42). At least one second aperture (44) is formed between the first and second surfaces (38, 40) of the stencil (34).
