2. Adhesive Application
1. Thin or insufficient adhesive can cause the chips to
loosen or become disconnected during flow soldering.
The amount of adhesive must be more than dimension c,
shown in the drawing at right, to obtain the correct
bonding strength.
a=20 to 70µm
b=30 to 35µm
c=50 to 105µm

2. Low viscosity adhesive can cause chips to slip after
mounting. The adhesive must have a viscosity of
5000Pa • s (500ps) min. (at 25°C).
