Assembly of Cards and Boards,and its structural analysis features. The length, height, and depth (. × . × .) 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.

Analytical Theory and Experimental Work in Compliant Leaded Systems Subjected to Twisting,In the previous chapter we discussed an approximate engineering approach founded on the premise that corner leads alone carry stress between module and card. The validity of this idealization deteriorates with decreasing lead spacing and lead stiffness and with increasing module stiffness.

Plated Holes in Cards and Boards,Plated-through holes (PTH) provide a current path between internal and/or external conductive patterns across the depth of a multilayer interconnection card or board (MIB). A (programmable) via connects two inner-plane (IP) copper layers for signal conduction (Fig. 13.1).
