use of broad signal conductors which may result in a wave impedance of 50 W or
less should be avoided in TTL circuits, as the IC may be damaged due to large
negative voltage spikes. Also, very high impedance lines ( ≥ 200 W) should also
The joint is not at acceptable, if the side joint lengthD is less than the lead width.
The lead width is measured from the toe to mid-point of the heel bend radius as
shown in Figure 13.41. The joint is acceptable if minimum side joint length (D) is
It needs to be mentioned here, that with the increasing track density of the boards
, the spacing between the tracks becomes much less than the diameter of the nail
. Hence there is a question mark in the industry about the bed-of-nails method ...
