    Abstract: A printed circuit board includes a plurality of lands thereon. The size D2 of the outer land 3 in the direction along the outside array is less than the size D1 of the inner land 1 in the direction along the inside array. Therefore, it is possible to pass the pattern 4 with enough clearance against the outer land 3. The outer lands 3 are formed with an oval, elliptical or oblong shape. Namely, the size D3 of the outer land 3 in the direction perpendicular to the direction of the outside array is greater than the size D2. Then, it is possible to ensure a sufficient reliability of a soldered part. Preferably, the connected area 5 between the inner land 1 and the pattern 4 and the connected area 7 between the outer land 3 and the pattern 6 are formed as a shape of a tear-drop. Then, the patterns 4, 6 cannot be easily cut by a thermal stock or a heat cycle. The solder resist 8 is coated, around the outer land 3, from an outer area to an inner area of the outer land 3, except for the central area 3A. The resist 8 is further coated, around the inner land 1, from an outer area to an inner area of the inner land 1, except for the central area 1A. Then, each area 5, 7 is reinforced by the resist 8. Further, since a clearance between exposed areas 1A and a clearance between exposed areas 3A are widened, a bridge of solder does not easily occur.

    Abstract: A heat transfer apparatus is carried on a substrate (204) having top and bottom surfaces (212, 214). The heat transfer apparatus includes a pad (220/222), at least one via (224/226), and a plurality of pads (302). The pad (220/222) is carried on the top surface (212) of the substrate (204) to electrically connect to an electronic component (228/230). The via (224/226) intersects the pad (220/222) and extends between the top and bottom surfaces (212, 214) of the substrate (204). The plurality of pads (302) are carried on the bottom surface (214) of the substrate (204) beneath the pad (220/222). The via (224/226) intersects one of the plurality of pads (302) to transfer heat generated during operation of the electronic component (228/230) thereto.

    Abstract: A method and an apparatus align and attach a leadless surface mount component (402) including a termination at each end of the component (402). The termination has bottom (704) and end (702) portions for attaching to a corresponding pad on a substrate (102) by a reflow solder process (1200). A pad arrangement (100) is formed including two opposite pads (108), each pad (108) occupying a tri-oval-shaped area. The tri-oval-shaped area includes an elliptical area (110) substantially centered under the bottom portion (704) of the corresponding termination of the component (402) when the component (402) is aligned with the pad arrangement (100), and an arcuate area (112) contiguous with the elliptical area (110) and extending towards the opposite pad (108) in a central lengthwise direction. A solder paste (202) is applied to the elliptical area (110), and thereafter reflowed, whereby solder (302) in the solder paste (202) liquefies and flows onto the arcuate area (112), thereby facilitating alignment of the component (402) with the pad arrangement (100).
