Compliant Mounting Mechanism

       A mounting mechanism is shown and described for a
thermode blade used in reflow processes or the like without inducing
lateral pressure effects in component leads.  Lateral movement of
thermal blades during contact with leads of TAB devices or the like
is to be avoided.

      In the figure, guide 2, including crossarm 4, is slidingly
supported by a bracket (not shown) and a spring biased into position
in pivot block 6.  Crossarm 4 includes in its extremities cam members
8 and 10 which ride on the angular rims of openings 12 and 14.

      When an out of parallel contact condition occurs, for example,
with first contact at only one corner of blade 20, pivot block 6 will
pivot about this point aligning crossarm 4 to angular planes of
openings 12 and 14.  This condition allows a straight pressure to be
exerted at blade 20 contact surface without lateral force.
