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.

The chip's electrode thickness and land thickness must

also be taken into consideration.

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).
