Assembly of Cards and Boards
As an example for the circuit card and board assembly of a computer, in most of this chapter we shall describe the IBM 9370 card enclosure system  and its structural analysis features. The length, height, and depth (L × H × D) dimensions of the assembly are 38 × 30 × 27 cm (15 × 12 × 11 in.). The major structural elements (Fig. 14.1) are 1) the frame, 2) planar boards, 3) card-to-board connectors, and 4) the cards.
