1. A concrete panel pre-pour marking system comprising:
a portable stand with means at the lower end of said portable stand for supporting the stand in an upright orientation from a generally level floor surface;
said portable stand having at its lower end a reference member configured to generally point to a designated starting point on said generally level floor surface;
an upper end of said portable stand having programmable processing means for processing software related to desired features of concrete wall panels to be formed and poured, a computer medium device for reading previously saved data on a recordable medium related to said concrete wall panels to be formed and poured in electrical communication with said programmable processing means, a display screen in electrical communication with said programmable processing means for viewing inputted information and said previously saved data from the recordable medium, keypad means for inputting said information in said programmable processing means and for initiating operational features of said system;
means for directing a laser light beam to one or more desired reference points on said generally level surface to mark said one or more desired reference points prior to forming and pouring concrete to make a desired concrete wall panel, wherein said one or more desired reference points are in relation to said designated starting point and said one or more desired reference points are selected from the saved data for a selected concrete wall panel to be formed and poured.
2. The system according to claim 1, wherein said system is powered electrically with an AC source, a DC source or a combination of said AC and DC sources.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A printed substrate comprising:
a plurality of pads provided in a mounting area, and having a polygonal shape, in which an electronic component is mounted; and
a hole facing and extending along at least two adjacent sides of the polygonal shape.
2. The printed substrate of claim 1 wherein the hole at least comprises:
a first hole extending along a first side and a second side of the polygonal shape; and
a second hole extending along a third side and a forth side of the polygonal shape and being apart from the first hole.
3. The printed substrate of claim 2 wherein the first side and the third side oppose to each other in the polygonal shape, and the second side of the forth side oppose to each other in the polygonal shape.
4. The printed substrate of claim 2 wherein the hole comprises:
a third hole extending along the first side and the forth side of the polygonal shape and being apart from the first hole and the second hole; and
a forth hole extending along the second side and the third side of the polygonal shape and being apart from the second hole and the forth hole.
5. The printed substrate of claim 1 wherein: the electronic component comprising a plurality of solder bumps connecting with the plurality of the pads and being mounted in the printed substrate; and the hole faces an edge of the electronic component.

7. An electronic device comprising:
a printed substrate comprising:
a plurality of pads provided within a mounting area, having a polygonal shape, in which an electronic component is mounted; and
a hole facing and extending along at least two adjacent sides of the polygonal shape; and
a housing housing the printed substrate.
8. A printed substrate comprising:
a plurality of pads provided in a mounting area, having a polygonal shape, in which an electronic component is mounted; and
a hole facing a corner portion of the mounting area.
9. The printed substrate of claim 8 wherein:
the electronic component comprising a plurality of solder bumps connecting with the plurality of the pads and being mounted in the printed substrate; and
the hole facing a corner portion of the electronic component.
10. An electronic device comprising:
a printed substrate comprising:
a plurality of pads provided within a mounting area, having a polygonal shape, in which an electronic component is mounted; and
a hole facing a corner portion of the mounting area; and
a housing housing the printed substrate.
