Abstract
A printed circuit board (100) includes a plurality of through-holes (140) defined therein, a plurality of first solder pads (110) defined to surround the through-holes respectively, and a second solder pad (190). Each of the first solder pads includes a first soldering zone (112) for accommodating solder used in a soldering process and a second soldering zone (114) for receiving excess solder overflowing from the first soldering zone. The second soldering zone is in communication with and extends outward from the first soldering zone. The second solder pad is located on a tail end of the printed circuit board for receiving excess solder of the tail end during the soldering process.

9. An assembly comprising:
-
a component with a plurality of pins symmetrically distributed at one side of said component with respect to a central line of said side; a circuit board configured to electrically mount said component thereon and abut against said side of said component, a plurality of through-holes defined in said circuit board to allow said plurality of pins correspondingly passing therethrough, a plurality of first solder pads defined on a side of said circuit board facing away from said component to respectively surround said plurality of through-holes, each of said plurality of first solder pads comprising a first soldering zone surrounding a corresponding one of said plurality of through-holes for accommodating a desired amount of solder thereon in a soldering process, and a second soldering zone extending out of said first soldering zone along a direction perpendicular to said central line of said side of said component for accommodating excess solder from said first soldering zone thereon in said soldering process. - View Dependent Claims (10, 11)

12. A printed circuit board, comprising:
-
a plurality of through-holes defined therein; a plurality of first solder pads symmetrically distributed at a side of the printed circuit board about a central line of the side to surround the through-holes respectively, each of the first solder pads comprising a first soldering zone for accommodating a desired amount of solder thereon in a soldering process and a second soldering zone for receiving excess solder during the soldering process, the second soldering zone in communication with and extending outward from the first soldering zone, an axis of each of the second soldering zone and the central line cooperatively defining an angle; and a second solder pad located on a tail end thereof for receiving excess solder of the tail end during the soldering process; wherein the angle of the second sildering zone of each of the first solder pads arranged in one column adjacent to the second solder pad is different from the angle of the second sildering zone of each of the first solder pads arranged in other columns. - View Dependent Claims (13, 14)
