Study of a dipping method for flip-chip flux coating
Flow process is analyzed by using two indicators including reflective area ratio and flow velocity. Stably reflective area ratio of glue is associated with gluing speed instead of viscosity. Different gluing speed changes the amount of the glue transferred to the groove. Flow velocity of glue is related with gluing speed, a greater gluing speed leads to greater maximum flow velocity. Larger gluing speed gives greater inertial force to the glue.
