초록 ▼

A printed circuit board assembly which is capable of being inserted and removed from the system to which it is electrically connected, even when fully populated with connected printed circuit cards, comprises a multilayer structure. A middle layer printed board is sandwiched between a nonconductive base on the bottom and a stiffener disposed on the top. The stiffener is preferably electrically conductive to provide an EMI (electromagnetic interference) shielding function. The base support and stiffener together support a mechanism for insertion and removal of the entire board via an edge connector disposed along a back edge of the board.

대표청구항 ▼

1. A circuit board assembly, which is especially effective for insertion and removal from a cabinet or an enclosure even when fully populated with printed circuit cards, said circuit board assembly comprising: a printed circuit board, having a first side and a second side, and also having a circuit board edge connector disposed along one edge of said board and further including at least one printed circuit card connector disposed on said first side of said board; a nonconductive planar supporting base substantially coextensive with said printed circuit board and disposed on said second side of said printed circuit board; and a stiffener disposed on another edge opposite to said one edge and also on said first side of said printed circuit board, said stiffener also being substantially coextensive with said printed circuit board. 2. The circuit board assembly of claim 1 in which said stiffener is metal. 3. The circuit board assembly of claim 1 in which said base is a polymeric material. 4. The circuit board assembly of claim 1 in which said printed circuit board further includes electrical connectors disposed thereon for insertion of printed circuit cards, said connectors for insertion of said printed circuit cards extending through apertures in said stiffener. 5. The circuit board assembly of claim 4 further including a plurality of guides having slots therein with said slots being aligned with and disposed adjacent to said printed circuit card connectors, said slots extending substantially parallel to one another and to said printed circuit board, whereby cartridges, which contain said printed cards and which have ridges matching said slots, may be slidably engaged with said printed circuit board. 6. The circuit board assembly of claim 5 in which said guides comprise an integral polymeric structure. 7. The circuit board assembly of claim 1 in which said stiffener comprises metal and includes apertures therein for the insertion of a flexible conductive strip. 8. The circuit board assembly of claim 7 further including said flexible conductive strip. 9. The circuit board assembly of claim 1 in which said base includes at least one recessed slot therein so as to accommodate a mechanism for insertion of said board.
