TITLE: CIRCUIT BOARD CONNECTIONS
FIELD OF THE INVENTION: This invention relates to circuit board connections and methods of connecting circuit boards to provide circuit boards of a desirable format and to provide such boards with a xigid structure.
BACKGROUND OF THE INVENTION: Circuit boards or cards provide the essential circuitry for many electronic products, including micro computers.Thus, the boards may bear printed circuits connecting microprocessors, transistors etc. These boards are often arranged in stacks which may be electrically connected.
It may be necessary to disconnect a board and replace it if some component on ~eboard proves faulty.
Personal computer cards are of great interest ~o designers of equipment for technical, industrial or professional applications because of the broad range of cards available, the great variety of software and, typically, the a~ailability of more than one source of supply. The electronic equipment on such cards is generally very good, it is only the mechanical side which causes problems.
A particular problem which has developed over the years relates to variatior.s in dimensions, for example, of personal computer cards from different sources, withrespect to carrier boards so that the cards cannot be mounted in well-defined positions on the boards. This can, for example, result in mechanical instability if the computer cards carmot be attached rigidly to any brackets provided.
Another serious problem which has developed relates to the lack of mechanical stability of stacks of certain circuit boards, particularly personal computers and microcomputers. For example, a personal computer card bearing printed circuits and electronic components may be "attached" to a carrier board. The "attachments"
AM~D~3D SH~Er IPEAJAU
PCI~AU 9 3 /' O 0 1 4 4 21328~2 RECEI~D 2~ MAY1994 ' .
may comprise, for example, a single, vertically-oriented bracket mounted at one edge of the computer card and the electrical connections either between individual boards or to individual boards from external power sources or peripheral items of equipment. Neither type of "attachment~' is satisfactory. Thus, the computer card may shift up and down around the point or points of attachment. Furthermore, theelec~ical connectors are not designed to provide~ stability to the structure.
Another problem which occurs relates to loose cables in compartments holding circuit boards. If the circuit boards are misaligned or relatively free to move within the compartment, this looseness in. itself increases the difficulty of maintenance.
Even "maintenance"causes problems where the "repairer" makes wrong connections. It is another object of this invention to eliminate the need to connect or disconnect individual cables when inser~ng or removing a circuit board.
A considerable number of inventions relating to plug-in modules have been published in the patent literature. Many of these inventions incorporate rail guidance systems. The present invention is not related to such plug-in modules.
In Australian patent no. 609017 (36746/39) Teknekron Infoswitch Corporation a plug-in card module is described. A printed circuit board forming part of the module is provided with elongate rail means to receive an electronic circuit board "slidably supported in each pair of elongate guide rails". The present invention is not concerned with such a plug-in card module or with such slidable support means for electrical circuit boards.
This invention has three principal objects, firstly, to provide a carrier for circuit boards of differing dimensions so that a circuit board in one format may be converted to a different format and, accordingly, be usable in a modular form, A~D~D SHET
IPEA/AlJ
PC~/AU 9 3 / O O 1 4 4 21328 RE~ 20 MAY199 secondly, to improve .he mechanical stability of stacks of circuit boards and thirdly, to make maintenance of circuit boards easier and less prone to errors.
In this specification the word "format" is llsed to refer to the size and shape of a particular circuit board and also to refer to the placement of connectors in standardised positions.
Furthermore, in this specification the term "wafer assembly" refers to structures in which some of the original connectors to electronic components cards are free for access, for example, the edge connectors on such cards.
BRIEP SUMMARY OF THE INVENTION: This invention, therefore, provides a circuit board which comprises a carrier board, which functions as a base structure and does not itself support any electronic components, to which is attached rigidly an electronic components card to form a wafer assembly, the card being attached to the carrier board by at least two rigid, mechanical connectors as defined herein, the electronic components card being provided with an edge connector for electrical connection to electronic components and the carrier board being provided with anedge recess sufficiently large to allow convenient electrical access to the edgeconnector, which is of such dimensions that it fits within an area defined by a geometrical projection of the edge recess.
This invention further provides an array or stack of such circuit boards which comprises a plurality of circuit boards attachable movably or irremovably with respect one to another~
This invention further provides a method of constructing a circuit board according to the invention, which comprises the steps of:

BRIEF DESCRIPTION OF THE DRAWINGS: Embodiments of the invention are illustrated in the accompanying drawings in which:-Figure lA is a plan view, Figure lB is an exploded perspective view of oneexample of a circuit board according to the invention and Figure lC is a detail of a component shown in Figure lA and lB; and Figure 2A is a perspective view of a single circuit board according to the invention with an attached front panel and Figure 2B is a perspective view of a stacked set of the circuit boards of Fi~re 2A.
DETAILED DESCRIPTION OF THE INVENTION:
This invention has ~articular reference to personal computer cards, more particularly computer cards made to comply with IBM PC physical format.
It is desirable to have carrier boards of a standard size which are sufficientlyextensive in area to accommodate electronic components cards of various sizes.
Thus the standard-sized carrier boards may be arranged in stacks housed in standard-sized racks.
The "rigid, mechanical connectors" are connectors which do not provide electrical connection between electronics components. They are, for example, fasteners of asuitable inert plastics material which may be glued to the carrier boards and cards to A~D~D SHE~T

maintain them a~ a selected separation. Alternatively the connectors may comprise screws or nuts, bolts and spacer means, the spacer means being adapted to maintain the carrier boards and cards at a selected separation. The essen~al criterion is that the connection between the carrier boards and cards must be such that the components are substantially rigidly connected given normal usage over the life-span of an item of equipment comprising ~e carrier board/card components.
If the card is generally rectangular in shape, as is usually the case, it is convenient to position the connectors at each corner of the rectangle. Alternatively or in addition it may be desirable for greater rigidity to position one or more connectors at a point or points along each side of the rectangle.
Turning to the construction of an array or stack of a plurality of circuit boards, it is convenient to slot the edges of such circuit boards into an arrangement of elongated apertures, positioned to receive the edges, in a suitable rack, for example, to comply with existing international standards. The circuit boards themselves can, of course, be arranged horizontally or vertically.
Wi~h respect to ~e method according to the invention, a card may be aligned withdesignated regions of the carrier board by use of a jig or template. Thus, where a numt~er of cards and carrier boards are to be assembled to form a circuit board, the operation may be automated by any suitable means.
Turning to the drawings, in Figure lA and lB a circuit board 1 comprises two principal components, a carrier board 2 which is attached, to form a wafer assembly, to a computer (electronic components) card 3 by means of a rigid, mechanical connector 4. This connector 4 takes the form of a bolt 4A provided with a washer 4B
and nut 4C and is located adjacent one corner of card 3. Separator pads 5 are located AM~DE ;D SH~T
